Insights and observations from 16 years of beekeeping.
Apoorva BV is on a mission to protect some of the world’s smallest, yet most important, creatures: honey bees. His journey started with a childhood curiosity, one that grew with the guidance of his mentor, Shanth Veeraiah S M. Over time, that interest turned into a mission to reconnect people with nature.
Sixteen years ago, he left his career in engineering to pursue his passion for beekeeping. Today, as the founder of Kodagu Bee Farm and the Hive Trust, he leads India’s urban beekeeping movement.
During peak season, his phone rings constantly, sometimes up to 200 times a day. But these calls aren’t panicked requests to remove bees. People now want to learn how to live with them!
In Bengaluru, he’s helped hundreds of people turn their rooftops into bee-friendly spaces. But Apoorva’s mission goes further. He’s raising awareness about the global decline in insect populations and what that means for our food. He’s also challenging the honey industry to clean up its practices and promoting beekeeping as a vital part of small-scale farming.
As Apoorva looks back on his journey, it’s clear how far he’s come from that first spark.
Q. How did you get into beekeeping?
A. In my third year of engineering, I started beekeeping as a hobby. After that, I travelled across the country to study successful beekeeping models. I returned to Bangalore and started both a beekeeping and supplies business in 2014.
Q. Can you explain the misconceptions people have about bees and beekeeping?
A. The main misconception is fear, and that’s something we need to address. Beyond fear, there are other aspects of bees that we have overlooked for ages.
We live in a subtropical country, surrounded by bees and snakes. Right now, there are about 300 pairs of eyes watching me, but I’m not watching them. Just because we haven’t observed them doesn’t mean they aren’t there.
There are some minor misconceptions too. For example, people say that during full moon nights, bees will come, and on Amavasya (new moon), they will leave. In reality, bees migrate to specific ecosystems whenever they need food, mating opportunities, shelter, and nesting habitats.
Q. What does a day with bees look like for you?
A. By 5.30 am, they start foraging, around the same time birds begin to chirp. They collect nectar, pollen, and water, which are essential for the colony’s sustainability. Around noon, they return because when the sun is directly overhead, it affects their navigation.
After 12 pm, they assess natural conditions—if it’s too hot, they won’t venture out. If the temperature exceeds 33-35 degrees Celsius, the foragers stay back and fan their wings to control the temperature.
They instinctively know which trees and plants blossom in the morning and evening and where they can collect more nectar. They use natural instincts to tell time and even use pheromones to navigate.
At night, they don’t sleep like us. When there’s no navigation or foraging outside, they stay busy with other tasks like wax production, organising food for easy access, and converting nectar into honey. Bees never sleep, which is why they’re called busy bees.
Q. In your experience as a beekeeper, can you emphasise how important bees are for our ecosystem?
A. Bees are considered keystone species. When bees are present in an ecosystem and are able to pollinate, everything else begins to flourish. Bees are responsible for about 86% of pollination on earth, which is why we have such a variety of fruits, vegetables, and even wild plants. This is why we say pollination is a primary service. The presence of bees signifies the sustainability, and biodiversity of an ecosystem.
For a farmer, integrating bees into their farm ecosystem is crucial because it’s the only way to ensure reliable pollination.
Q. What are some key characteristics to look for when identifying high-quality honey?
A. Honey is one of the most contaminated foods in the world because it’s difficult to collect and harvest. Worker bees require suitable conditions to convert nectar into honey.
We have the Western Ghats, Eastern Ghats, Deccan region, Himalayan biosphere, desert flora, and a coastline. With this diversity, we have over 3,000 varieties of honey.
There are plants in the Western Ghats that bloom during the monsoon, producing honey so bitter that even a spoonful is difficult to eat. Some varieties of honey from wild flora are naturally sour, while sunflower honey is very sweet.
When I offer sunflower honey to people from the Western Ghats, they often reject it as impure, assuming I’m trying to cheat them. To them, their local honey is the only pure honey.
I’ve tasted many varieties of honey and have memories of all those flavours. I can judge honey to a certain extent. But what about the average consumer who has only tasted the honey available in stores?
Consumers need to understand how honey is made and should participate in the process. They should step out of their comfort zones and learn about the efforts farmers make to harvest honey. Adulteration is widespread, and only scientific laboratory tests can identify impurities. It can’t be tested in the kitchen.
Q. Can honey truly last forever if stored properly, or is this just a myth?
A. Honey contains high concentrations of sugars, which prevent bacterial growth. While you may observe some bacteria under a microscope, they remain dormant and cannot multiply or function. However, if honey is exposed to moisture, there is a risk of yeast cells multiplying. After use, make sure the lid is tightly closed to avoid exposure to atmospheric moisture, as it may cause fermentation.
In Egypt, edible honey was discovered that was more than 1,000-2,000 years old. This indicates that honey has no fixed shelf life and can be consumed if properly maintained and stored.
Q. Is there any difference between wild honey and the honey we get from boxes?
A. Wild or forest honey is considered a tribal right. Tribals are gatherers who climb trees and hunt for honey, a process known as honey hunting, not beekeeping. They use smoke, cut the entire comb, and extract honey predominantly from a species called Apis dorsata. They also collect honey from Apis cerana, but in very small quantities.
During harvesting, if the comb falls and touches the soil, it may be handled with bare hands. Due to these factors, it is called wild honey. To access it, we must purchase it from their society. We should not casually use terms like ‘wild’ and ‘forest’ for honey.
Some brands market their products as forest honey, but this practice is not sustainable due to climate change and competition. When you visit a store, you may find jars labelled as forest honey alongside others. Naturally, you may be inclined to choose the forest honey. Increased demand leads tribals, who once collected only minimal quantities of honey for their sustainable lifestyle, to collect more.
Moreover, there is no system to monitor how bees are treated in the forest. Tribals are the primary custodians of the forest. They were protecting it long before departments and ministries were established.
Q. Is there a noticeable difference in taste or consistency in wild honey?
A. Yes, because Apis dorsata can forage up to six to eight kilometers, while Apis cerana can forage up to 500 meters to one kilometer. This difference in foraging range results in variations in floral sources, which in turn affects the taste of the honey.
Another factor is that when honey is collected by these gatherers, it is often squeezed rather than centrifuged. Sometimes they squeeze out stored pollen, which may be slightly fermented, or laurel water gets mixed up. These factors also influence the taste.
Q. Can you provide some numbers on the decline in honeybee populations compared to previous years?
A. Forty percent of insect biomass on Earth is on the verge of extinction, including indigenous and solitary bees. However, imported bees can be bred and multiplied more easily using twin-rearing techniques and other methods.
In South India, we practise indigenous beekeeping methods. We do not force bees to breed; instead, we allow them to breed naturally, much like other animals. There is no captivity in beekeeping; bees are free to leave if they don’t like the environment or the beekeeper.
We employ specific methods only during their natural breeding season. Before they naturally divide, we separate them into another beehive and provide a nesting habitat. Beekeeping in India is a different story compared to the West.
Providing space for bees is a form of conservation.
When people say we are saving the wrong bees, they are usually referring to the US, not India. In urban areas like Bengaluru, I rescue colonies that have taken up residence in chimneys and bathrooms. There are hundreds of urban beekeepers in Bengaluru who practise beekeeping on their terraces, balconies, and in their compounds. Providing space for bees is a form of conservation.
Q. Can you highlight some common adulteration practices?
A. Traditional adulterants include jaggery, sugar, and molasse. Now, advanced adulteration technologies from other countries are introducing high-fructose syrups made through hydrolysis (a chemical process that breaks sucrose into fructose and glucose). Laboratories need the competence to test these, but many lack this capability.
Adulterants are increasing day by day, and new technologies are emerging to detect them. It’s crucial for consumers to be vigilant. My point is that adulteration will happen.
As consumers, understanding how products are grown and reach the market is vital. If you rely solely on the label, you’re taking a significant risk.
Q. What is the average income of a farmer keeping honeybees? Could this be a side income for smallholders?
A. In 2021, the Agricultural Ministry and the Indian Council for Agricultural Research (ICAR) released an official statement highlighting that beekeeping is as important as soil for agriculture. This means that without pollination, farmers cannot expect yield or productivity.
In some farm ecosystems, integrating beekeeping can increase the income of small-scale farmers, not just through schemes and policies. For example, the productivity of oilseeds and even coconuts can increase by 25%. In the case of sunflowers, you can expect 50% more produce. Beekeeping can also boost areca nut harvests by one to two quintals, adding around one lakh rupees per acre. The increase in productivity isn’t just about the number of seeds but also the oil content, size, and weight.
Pollination is an ecological service—it’s not just for your benefit.
In beekeeping, the direct income comes from honey, while the indirect income comes from pollination. Pollination is an ecological service—it’s not just for your benefit.
Some farm ecosystems can yield 5 kg of honey per year, while others may only produce 2-3 kg. The yield depends on where you’re beekeeping and the number of plants and trees within a 500m to 1km radius.
The global economic value of pollination is estimated at around 400 billion dollars. In India, we lack specific data on how much crop production results from animal pollination and the number of natural and domesticated colonies.
There is a device called a pollen trap used to collect coconut pollen, which contains 28-30% more protein—a ‘gold’ for athletes. We need case studies comparing the yields of farmers who have integrated bees and those who haven’t.

Meet the superfood that's been right under our noses all along
"Try the fish. It's cooked in a multivitamin leaves gravy," urges Jaywant Chowgule, the owner of Mangaal Farmstay, as he nudges me towards a special item on the day’s lunch menu. We were there celebrating a friend’s birthday, enjoying a wholesome, delicious set lunch, when Jaywant mentioned the leaves—something I'd never heard of before. My curiosity piqued, I eagerly served myself a generous helping of the forest green dish.
After lunch, we walked over to a short tree where Jaywant reached up and plucked a few leaves. The leaves spread symmetrically from a central stalk, with the largest, around 4 cm in length, at the base, and smaller ones, about 1.5 cm long, higher up the stem. They resembled the Star Gooseberry plant, which I mistakenly assumed they were. But Renuka Vijairaghavan, a 66-year-old sustainable lifestyle coach from Pune, corrected me.
"Multivitamin leaves plant is Sauropus Androgynus and Star Gooseberry plant is Phyllanthus Acidus. They look similar, but they're entirely different. Even some scientists make this mistake in their reports," she explained. Renuka grows the plant herself and regularly includes the leaves in her diet, sometimes eating them raw after pruning to get those extra nutrients.
Sauropus Androgynus, known as sweetleaf or Multivitamin leaves, among other names, is usually found in Southeast Asia—particularly in India, Bangladesh, and the Guangxi, Guangdong, Hainan, and Yunnan provinces of China. This easy-to-grow plant thrives in warm, tropical climates and can reach up to 6 metres if left unattended. Widely known as Katuk or Cekur Manis in South East Asia, the sweet leaf is known to have a nutty flavour profile with a taste between peas and asparagus. In India, it’s also called Chakramuni or Thavasi Keerai.
One of the most striking aspects of sweetleaf is its protein content, comparable to that of soybeans, making it especially appealing to vegetarians and vegans. It’s also rich in antioxidants, provitamin A, carotenoids, and vitamins B, C, and D. In fact, it has more phosphorus than a banana and is loaded with calcium. Dr. Hock Eng Khoo’s research highlights the plant's abundance of both macro and micronutrients, nearly all our bodies need.
Sweetleaf has long been used in folk (unani) medicine for treating coughs, wounds, urinary disorders, and fevers, thanks to its anti-inflammatory and antibacterial properties. Dr Maryanne Lobo, an Ayurveda physician and agroforestry consultant, says, "Though not widely mentioned in Ayurvedic texts, these leaves are known to lower cholesterol, strengthen bones, alleviate cancer symptoms, and cure infections." In Indonesia, the leaves were traditionally used to increase breast milk supply. Their high lutein content benefits eyesight and digestive health.
Though not widely mentioned in Ayurvedic texts, these leaves are known to lower cholesterol, strengthen bones, alleviate cancer symptoms, and cure infections.
In Tamil Nadu, Thavasi Keerai (another name for sweet leaf) is used for its detoxification properties. Its flavonoids and carotenoids boost the plant’s ability to act as an anti-carcinogen, anti-diabetic, anti-inflammatory, and antioxidant. It’s also an excellent wound healer, featured in various gels and creams. Folklore even claims it can reduce snoring and teeth grinding—a remedy many wives might be eager to try on their husbands!
Given its robust nutritional profile, it’s surprising that sweetleaf isn’t a culinary star. This herb has been used for decades in traditional recipes across China, India, and Thailand. Shruti Tharayil, a forager who educates others about wild greens through her Instagram, Forgotten Greens, regularly picks and eats these leaves. In Goa, Tanya, the owner of Edricia Farms, grows and sells them. Most of her customers, including chefs, eat them raw in salads or lightly stir-fried.
In South India, Sweetleaf is commonly used in Thambli, a chutney made by grinding the leaves with curry leaves, mustard seeds, cumin, lentils, and grated coconut. Many South Indians also fry the leaves until crispy, enjoying them as a side with rice and dal. The younger leaves can be eaten raw, added to salads, or blended into smoothies for a nutritional boost. The mild, slightly sweet flavour pairs well with a variety of ingredients.
Chef Sandeep Sreedharan was "adventurous enough" to combine multivitamin leaves with clams. He says, "We used to call it Madura Cheera in my hometown in Kerala - it means sweet leaf. The most common preparation we had was with half-cooked lentils. I grew up eating this."
But he cautions against eating it everyday, saying, "It is a very strong leaf. And once the plant fruits, the taste of the leaves changes and they are not very nice."
While the leaves offer numerous benefits, overconsumption can lead to health issues. The compound papaverine, which helps relieve constricted blood flow, can cause lung damage if consumed in excess, leading to a condition known as bronchiolitis obliterans.
I found a consistent supply of these leaves through a friend’s garden. Although they don’t cook with them, they’re happy to share. I’ve sneaked these leaves into various recipes. My north Indian roots led me to attempt a version of palak ka saag with these leaves. With a dollop of fresh cream, it tasted divine—knowing it was more nutritious than the traditional spinach or mustard leaf version made it even better. Yet, given the potential side effects, I resist the temptation to cook it too often.
With its ease of growth, medicinal properties, versatile flavour, and impressive nutrient profile, it’s puzzling that Sweetleaf hasn’t gained more culinary recognition. Perhaps it’s time for this humble leaf to step into the spotlight.
How India's second smallest state went 100% organic in just 13 years
In 2016, Sikkim became India’s first 100% organic state. Spanning approximately 7,000 km², it is the country’s second smallest state. However, this transition was not without its challenges.
The story begins in 2003 when chief minister Pawan Singh Chamling pledged to transition the state entirely to organic farming. Over 13 years, the hilly state eliminated chemical fertilisers and pesticides from its 76,000 hectares of agricultural land.
Sikkim had a head start with its minimal reliance on chemicals—its fertiliser use was only 5.8 kilos per hectare, significantly lower than the national average, thanks to its remote location.
Even as the rest of India embraced the green revolution of the 1960s, Sikkim’s isolation kept its soil relatively free from synthetic chemicals. This geographical advantage meant that the state’s agricultural output lagged behind more industrialised regions.
Bharati Rai, a farmer from Gaucharan village near Ranipool in Sikkim, said “Moving towards organic farming and restricting the use of chemicals and pesticides was done while keeping in mind the health of the people and the environment, including the health of the soil.” But the challenge was to implement this transition without putting the livelihoods of Sikkim’s thousands of farmers at risk.
Sikkim’s government opted for a gradual transition, learning from Sri Lanka’s mistake of an overnight ban on chemical fertilisers that led to a collapse in agriculture.
In 2003, Sikkim provided a 40% subsidy on urea, reducing it by 10% each year until 2008, when it was completely removed. This allowed farmers and the land to gradually adapt to organic farming. “The slow change towards organic farming over the years was ideal as it allowed us to prepare for the change, along with allowing the soil and land to slowly adapt to the new mode of farming,” Rai said.
Farmer and politician Dwarikanath Sapkota developed a transitional programme to help train farmers in getting accustomed to methods of growing crops without the use of chemicals. Training sessions were conducted by several agencies such as Sikkim Organic Mission (SOM), the state’s horticulture department, Krishi Vigyan Kendras, the Agriculture Technology Management Agency and the Indian Council of Agriculture Research (ICAR). The government established nurseries to cultivate earthworms, which were then distributed free of charge to farmers to initiate vermicomposting.
The government continued its earlier practice of distributing quality seeds at a cheap rate, but with a renewed emphasis on seeds for high-value fruits and vegetables that are suitable to grow in the particular climatic and geographic conditions of the region.
When chemical fertilisers and pesticides are completely phased out, it takes a while for the soil to recover its nutritional value for effective organic farming to be possible. During this period, government rations helped farmers survive. The government also gave cows to many families, ensuring a steady income from dairy farming. Another scheme was launched at this time, giving one government job to each family, making salaried income a means of survival for a lot of farmers. Bharati said the government tried to incentivise farmers with awards and monetary prizes for their achievements in organic farming.
The overwhelming popularity of Chamling, who won 31 out of 32 and 32 out of 32 seats in the 2004 and 2009 assembly elections respectively, meant that there was no sizable opposition to speak of. This allowed the government to push through these reforms and implement them in a timely manner.
As the state moved to organic farming, its cropping pattern started looking different. Rice, integral to the Sikkimese diet, has been reduced almost to half of what its yield used to be. Contrarily, there has been little change in yields of maize, another important crop. Acreage under wheat, finger millet, barley, pulses and oilseeds has been seeing a decline. Unsurprisingly, fruits and vegetables have seen steady growth.
"Since the change, farmers have been benefiting from the increased demand for organically grown crops. The prices of these crops are also high, and combined with the increased demand, the farmers are not negatively impacted by the changes. This demand comes from tourists, foreigners, and even locals who can afford them.” said Rai.
In 2014, legislation was introduced completely banning the use of all chemical fertilisers and pesticides. It was made a punishable offence with a hefty fine of Rs 1 lakh, up to 3 months in prison or both. Two years later, Prime Minister Narendra Modi declared Sikkim as India’s first, fully organic state. The state saw a 50% boost in the number of tourists between 2014 and 2017, owing to its newly found ‘organic’ reputation.
The vast majority of Sikkim still depends on food exports from Siliguri in West Bengal for its sustenance. Its organic produce is consumed by a minority within the state, and largely accrues profit through exports.
Reduced yields after the transition meant the government had to bolster prices to cover for the incurred losses, disincentivizing local customers from buying the organic produce.
Much of Sikkim's organic food is not marketed under the official ‘Sikkim Organic’ brand. This, combined with the lack of regulations on food imported from outside the state, means that organic products from Sikkim have to compete with exports from West Bengal. Grains, fruits and vegetables that come from West Bengal are cheaper and thus, preferred by the consumers in Sikkim.
In the fruit market, many prefer the exported, conventionally-grown fruits as they are bigger and more colourful. This has resulted in a significantly reduced market for the state’s own organic produce. “It is cheaper to buy food from outside states, and people do tend to prefer the more affordable option. However, farmers are still seeing an increase in demand for organically grown crops.” said Rai.
The state’s geographical isolation is another major issue. Any export has to travel about 80 kilometres by road to the nearest airport at Bagdogra, before it can reach anywhere else in the country. Given the short shelf life of organic produce, this is a difficult endeavour. Small and marginal farmers, who live in parts of Sikkim that are difficult to access, depend on middlemen to take their produce to towns and cities, lowering their profit margin. The initial promise of ‘higher prices despite low yield’ has not entirely come true.
Government support has been severely lacking in some areas. Many farmers have not been provided bio-fertilisers and biopesticides from the government and have suffered losses as a result. Between 2010 and 2014, only 5 percent of the total expenditure of SOM was allocated to farmer training. Therefore, efforts to help the farmers generate their own inputs have also not seen much success. Despite pest attacks being a huge concern among the farmers, there has been no attempt by the government’s agencies to collect data on this matter.
A major underlying cause of this government neglect is the lack of funds, which have been disproportionately directed towards getting the state ‘organic’ certified through Third Party Certification for international export. From 2010 to 2016, SOM has spent approximately 78 percent of its total expenditures on certification-related procedures. The government’s preoccupation with certification has meant that less funds are allocated to providing farmers with essential organic inputs and training.
Despite these challenges, Sikkim remains the sole example in the world of a complete transition to organic farming at its scale. Hence, it serves as a case study for governments, scientists and environmentalists looking to transform agriculture into a sustainable industry and make the food we eat nutritious and healthy.
Voluntary group promotes natural farming and water conservation
Balchandra Ahirwar, a Dalit farmer from Lidhoratal village in Madhya Pradesh's Tikamgarh district, owns just two acres of land. Despite limited resources, he has successfully implemented low-cost, local resource-based natural farming methods. His efforts have increased production and improved food quality, earning him a government award. He now trains other farmers in natural farming techniques.
He has developed a multi-layer vegetable garden and a small fruit orchard, cultivating up to 44 different crops in a typical year.
Balachandra entirely avoids use of any chemical fertilisers and pesticides from the market. Instead, he makes organic liquid and soil fertiliser and pest repellants on his farm. He has also established a natural farming centre, producing bio-fertilisers using only local resources. These are available to other farmers at a modest price.
His wife, Guddi, has significantly contributed to these efforts. She says, "The benefits of natural farming are clear, especially in terms of the money we used to spend on frequent medical treatments. By eating food grown naturally, we are much healthier now."
Phulbai Chadaar, a farmer with just one acre of land in Digaura village, also in Tikamgarh district, has similarly embraced natural farming. By growing high-quality fruits and vegetables, she has reduced costs and increased income, finding a ready market for her produce. “Earlier I was often pleading before someone for a small loan, now I can give one to you if you need it”, she says with a broad smile.
These success stories are among many emerging from the efforts of SRIJAN (Self-Reliant Initiatives through Joint Action), a voluntary organisation working in Bundelkhand, a region spread across 14 districts of Madhya Pradesh and Uttar Pradesh. SRIJAN's initiatives focus on three main areas:
SRIJAN’s initiatives often begin in Tikamgarh district and are then expanded to other parts of Bundelkhand through collaborations with grassroots voluntary organisations under the BIWAL (Bundelkhand Initiative for Water, Agriculture, and Livelihoods) program.
In Lapaanv village, Chitrakut district, a young woman named Kiran tends to her multi-layer vegetable garden, often chasing away monkeys. Despite challenging conditions, her family has created an organic vegetable garden of exceptional quality, attracting buyers to their remote location. Kiran says her father-in-law, Braj Behari, who was scheduled for eye surgery, experienced significant improvement in his eyesight after regularly consuming amaranth, a leafy vegetable.
In Elha, activist Gajendra reports significant increases in wheat and fodder yields, improved grain quality, and reduced costs in fields cultivated under SRIJAN's initiatives.
In Sakrauhan, Sarita has started a natural farming centre that also focuses on preserving traditional seed varieties. The introduction of multi-layer vegetable gardens has boosted both productivity and the quality of vegetables, which are easily sold in local markets.
In Churiyari of Mahoba district, Keshkali's natural farming centre has brought new hope to farmers. Vipin Tewari, a farmer from the village, has nearly doubled his yield in some fields.
In Thurhat, Ramesh Dada, who runs a successful natural farming centre, says even when his yield does not increase, the superior quality of his wheat allows him to command higher prices. Ghashyam, another farmer, takes pride in his bumper crop of high-quality watermelons.
In Khemkhara, a lotus pond known for its nutritious makhanas (fox nuts) was revitalised through desilting, greatly benefiting the village.
The cooperation achieved during these community conservation efforts has improved the prospects for such cooperation in future. In Markhera village, Tikamgarh district, the digging of doha water saving pits and check dam repairs has led to collective afforestation efforts and substantial contributions of voluntary labour (shramdaan).
The next phase of these initiatives involves food processing and marketing to increase income through value addition. A women's farmer producer organisation in Tikamgarh district has begun local extraction of groundnut and mustard oil, grading groundnuts, and producing desi ghee, among other products. Subsequently, the Ken-Betwa Women Farmer Producer Company was formed, named after the two main rivers of the region, which has 2300 rural women as its shareholders. Though still in its early stages, the company has already received promising orders for its natural farming-based products.
While these efforts have yielded significant benefits, there is even greater potential ahead. Combining these agricultural initiatives with social reforms, such as reducing the high consumption of liquor and tobacco (especially smokeless tobacco and gutkha) in the region, could further enhance the health benefits.
Doesn't taste much like sugar, and its safety remains uncertain.
Sugar is a common ingredient in many Indian dishes, but it has long been criticised for its negative impact on health. Consuming excessive amounts of sugar can cause dental decay, weight gain, increased risk of diabetes, and heart disease.
Unfortunately, popular fast-food chains and cold drink brands often incorporate sugar in their products, making it difficult to avoid this harmful ingredient.
Potato chips, tea, coffee, sweets, and many Indian dishes often contain added sugar, which can be unhealthy in large quantities. However, the prospect of giving up sweets may not be very appealing to the average consumer. Hence, many are turning to artificial sweeteners, which offer the sweetness without the negative effects. These sweeteners are made from plant extracts or chemicals and can be found in many sugar-free products.
But what are these artificial sweeteners? How did we discover them? What are they made of? Are they entirely safe? Let’s find out.
"Table sugar, also known as sucrose, is high in calories but low in nutritional value. Natural sugars found in fruits and vegetables are digested slowly and provide a steady source of energy, which is generally considered healthy. But when sugar is added to food and drinks as a sweetener or preservative, it’s probably bad news. According to the NHS, adults shouldn’t consume no more than 30 grams of added sugar per day.
Artificial sweeteners work by providing the same level of sweetness as sugar, or even more, with almost no calories. This is why they are called non-nutritive sweeteners (NNS). The Food Safety and Standards Authority of India (FSSAI) has approved the following artificial sweeteners for use in food: saccharin sodium, aspartame, acesulfame potassium, sucralose, neotame, and isomaltulose.
Saccharin is the oldest artificial sweetener on the market. It comes in granule and liquid forms and is made by chemically modifying o-toluene sulfonamide or phthalic anhydride through the process of oxidation.
Saccharin was discovered in 1879 by Constantin Fahlberg at Johns Hopkins University, Baltimore, while he was experimenting with benzoic sulfimide. The discovery was allegedly accidental, as Fahlberg noticed a sweet taste on his hand and named the compound after this observation. Fahlberg and his colleague Ira Remsen later developed a way to synthesise saccharin from o-sulfamoylbenzoic acid.
Saccharin is about four to five hundred times sweeter than table sugar, and hence required in far smaller quantities to do its job. This high sweetness and stability, as well as its long shelf life, make it an ideal choice for food manufacturers. Common applications include sugar-free sodas, candies, jams, jellies, and cookies.
According to the US Food and Drug Administration (FDA), the acceptable daily intake (ADI) of sodium saccharin is 5 mg per kilogram of body weight.
Artificial sweeteners, despite their widespread use, remain controversial due to concerns about their safety and benefits. While many people believe that switching to artificial sweeteners can aid weight loss, scientific evidence is inconclusive. The World Health Organization (WHO) does not recommend their use for weight loss, noting little to no reduction in body fat based on a 2022 review. Instead of relying on artificial sweeteners, it might be better to incorporate more nutrient-rich fruits and non-sweetened foods into one's diet.
A review published in the Indian Journal of Pharmacology highlights a lack of randomised controlled studies assessing the efficacy of artificial sweeteners across various population groups. Observational studies yield inconsistent and contradictory findings. Moreover, consumers are generally unaware of the potential dangers associated with the use of artificial sweeteners.
Aspartame, an ester derived from the amino acids L-aspartic acid and L-phenylalanine, is a good case in point. This dipeptide is combined with methanol to form the compound aspartame, which is around 200 times sweeter than sugar. Aspartame is extensively used in various food and beverage products and is generally considered safe for human consumption.
However, some potential risks have been identified.
The International Agency for Research on Cancer (IARC) has classified aspartame as ‘possibly carcinogenic to humans’, although the evidence is limited.
The Joint FAO/WHO Expert Committee on Food Additives has established the acceptable daily intake (ADI) of aspartame at 40 mg per kg of body weight. However, more research is needed to better understand the possible mechanisms by which aspartame may cause cancer.
Some research suggests that aspartame may pose a risk for people with Type-2 Diabetes. This is because it can increase cortisol levels in the body, potentially leading to weight gain and insulin resistance.
The widespread marketing and government approval of artificial sweeteners have contributed to their widespread use. However, due to the limited evidence of their benefits and potential health risks, consumers, particularly those with diabetes, need to exercise caution when consuming these products.
Unusually high temperatures in the second fortnight of February and March were responsible for the low crop yields.
Bhupen Singh, a farmer in Punjab's Bathinda district, witnessed his wheat harvest shrivel in 2022 due to unusual heat, peaking at a scorching 44.1°C during critical growing months. “Unusually high temperatures in the second fortnight of February and March were responsible for the low crop yields. It affected the wheat during its critical milking stage, resulting in smaller grains. Crops also experienced browning, premature maturation and shrivelled grains. Farmers, like me, suffered heavy losses,” said Singh.
According to the Indian Council of Agricultural Research (ICAR), average wheat yields in the district plummeted from 58.2q/ha in 2021 to just 41.6q/ha in 2022. Heatwaves in 2023 and 2024 have also affected wheat crop yields in the region, although specific data on the losses is not yet available.
Our planet's temperature has been steadily rising. Since 1880, Earth's temperature has been rising by 0.08°C per decade. But since 1981, it's more than doubled to 0.18°C per decade. Globally, hot days are increasing while cold days are declining. Research published in Science Advances shows that heatwaves are becoming longer and slower, particularly in North America and Eurasia. From 1979-1983, the world averaged about 75 heatwave events. Fast forward to 2016-2020, and the number had increased to 98.
While a warmer planet poses severe health risks for humans, it also significantly impacts agricultural output. For India, home to over 1.4 billion people and ranked 111 out of 125 countries in the Global Hunger Index, this presents a serious problem.
Most India Meteorological Department (IMD) stations have recorded an increase in heatwave events from 1961 to 2020. This summer, the country faced its third consecutive year of severe heatwaves, with temperatures in northern India crossing 50°C. What's even more concerning is the trend of these heatwaves starting earlier, lasting longer, and affecting larger areas – a troubling shift from historical climate patterns.
Studies project a temperature increase of 2.5 to 4.9°C across India, potentially leading to a decrease of 41%-52% in wheat yield and 32%-40% in rice production. This decline extends to most cereals, particularly in the Indo-Gangetic plains, where rising temperatures and reduced water availability are expected. Modelling approaches suggest a substantial loss in crop production, ranging from 10% to 40% by 2100.
“Some crops, vegetables, and fruits are more susceptible than others, depending on their genetic quality and agro-ecological needs,” said Anjani Kumar, senior research fellow at the International Food Policy Research Institute-South Asia.
Rain-fed crops: Crops, including sorghum, jowar, ragi, bajra, oilseeds, and vegetables, are particularly susceptible to longer dry spells, erratic rainfall patterns, and extreme heavy rain events. "These conditions could lead to lower yields per hectare or even crop failure, with a higher risk of pest infestations due to rising temperatures," said Shrinivas Badiger, PhD fellow at the Centre for Environment and Development, Ashoka Trust for Research in Ecology and the Environment.
Groundwater-irrigated crops: A warming climate accelerates groundwater depletion, threatening crops reliant on irrigation. "Higher temperatures elevate the water demand for evapotranspiration," said Badiger. "If this requirement isn't met, it will adversely affect yields even in irrigated regions." This could significantly impact water-intensive crops like sugarcane, rice, cotton, and wheat, making their cultivation increasingly challenging.
A 2019 United Nations report highlights the negative impact of climate change on staple crops, vital for global nutrition. While elevated CO2 levels may make vegetables like lettuce and tomatoes sweeter and increase yields, it comes at a cost. Studies show a decrease of 10 to 20% in protein, nitrate, magnesium, iron, and zinc content. Plants may lose up to 8% of their mineral content in these carbon-rich environments.

This translates to a rise in hidden hunger, a condition where people experience undernutrition due to a lack of essential nutrients despite consuming enough calories. A policy note from the Gender, Climate Change, and Nutrition Integration Initiative predicts 138 million more people could be at risk of zinc deficiency and 148 million more at risk of protein deficiency globally by 2050.
The most vulnerable regions include South Asia, Southeast Asia, China, the Middle East and North Africa, where many are already near nutritional deficiency and rely heavily on wheat and rice. In India alone, an estimated 53 million people could become newly protein-deficient, and 48 million could become zinc-deficient under higher CO2 levels.
“The precise impact of heatwaves varies according to the type of crop, soil conditions, and the local climate. So, more comprehensive research is required to fully understand and verify these effects and their implications for food security and dietary quality,” said Suvarna Sawant, chief dietician and HOD, clinical nutrition & dietetics, Nanavati Max Super Speciality Hospital, Mumbai.
Climate change demands a shift in dietary patterns, but the strategies differ across regions. In the West, reducing meat consumption is a major focus. However, meat and eggs remain essential protein sources in India, where consumption is already relatively low and these foods contribute significantly to meeting nutritional targets.
Substituting scarce items with readily available ones is another option, but challenges exist. No two foods are nutritionally identical, and even similar options can differ in calories, protein, and micronutrients.“For example, replacing whole grains with refined grains significantly reduces fibre and nutrient intake, while shifting from animal protein to plant-based alternatives requires careful consideration to balance amino acids and vitamins," said Sawant.
Here's where consumers can play a key role:
Reduce food waste: Globally, 931 million tonnes of food are wasted annually, contributing to 8-10% of carbon emissions. Reducing food waste lowers demand and mitigates further warming.
Prioritise fresh produce: Fresh, seasonal produce offers higher nutrient levels and fewer additives compared to processed foods.
Meanwhile, scientists and policymakers are working on equipping farmers with tools to manage losses:
Climate-resilient crops: Genome editing is making strides towards creating heat-resistant, nutritious crops. In 2021, Prime Minister Narendra Modi introduced 35 such varieties developed by ICAR, including drought-tolerant chickpeas and biofortified wheat, pearl millet, and maize. Biofortification is a process that increases the nutrient density of crops.
Weather information and agronomic practices: The IMD's Gramin Krishi Mausam Sewa scheme provides farmers with crucial weather and crop information to optimise production. "Farmers can adapt by diversifying crops, using resilient seed varieties, and modifying planting and irrigation practices," said Kumar.
For instance, in Uttar Pradesh this year, a 5°C rise in temperature resulted in mango flower drop and lots of jhumka problems in the fruit due to poor pollination. “To mitigate losses, we implemented ICAR-Central Citrus Research Institute (CCRI) and ICAR-Central Institute for Subtropical Horticulture’s advisories to initiate drip irrigation with organic mulching. Certain fungicides, such as copper oxychloride, were also recommended to control fruit infections that spike in rising temperatures,” said Uday Singh, a farmer in the Ayodhya district, where mangoes and guavas are the primary fruits grown.
There's no doubt that our planet is getting warmer, and heatwaves will only intensify. Only through informed, collaborative efforts at the community level and through government-led initiatives can India develop resilient food systems. Ongoing research and data collection can provide valuable insights, guiding effective interventions and policies aimed at preventing malnutrition, sustaining yields, and promoting overall health and well-being.
Antimicrobial resistance is making infections tougher to treat
Antimicrobial resistance, or AMR, is a fast-evolving threat to global health systems. According to the World Health Organization (WHO), AMR occurs when bacteria, viruses, fungi, and parasites no longer respond to antimicrobial medicines as they develop drug resistance.
In many wealthy countries, doctors frequently prescribe antimicrobials even when they aren't necessary, according to a paper published in the United States National Center for Biotechnology Information. Meanwhile, in developing nations like India, these drugs are often readily available over the counter, leading to rampant misuse.
A study in The Lancet Regional Health — Southeast Asia highlighted India's high consumption of broad-spectrum antibiotics, which should be used sparingly due to their wide-ranging effects. The journal JAC—Antimicrobial Resistance reported that antibiotic misuse varies significantly across India, with poorer states showing lower rates of consumption, likely due to limited access rather than prudent use. This misuse breeds superbugs—pathogens armed with resistance genes that render treatments ineffective. As a result, common infections become increasingly difficult, if not impossible, to treat.
According to a report published by the Indian Council of Medical Research, a big chunk of patients in India may no longer benefit from carbapenem, a powerful antibiotic used in critical care settings to treat pneumonia and septicemia. The resistance isn't limited to bacteria. Fungal pathogens like C. parapsilosis and C. glabrata are showing increasing resistance to common antifungal medicines such as fluconazole.
In 2019 alone, drug-resistant infections claimed 1.27 million lives globally. The United Nations warns that by 2050, this number could soar to a staggering 10 million annual deaths.
According to an article in the United States Centers for Disease Control and Prevention (CDC), antimicrobial-resistant infections that require the use of second- and third-line treatments can harm patients by causing serious side effects, such as organ failure, and prolonged care and recovery, sometimes for months.
The article further says that resistance also comes in the way of a person’s ability to fight infections using antibiotics during treatments/procedures, including joint replacements, organ transplants, cancer therapy, and chronic diseases like diabetes, asthma, and rheumatoid arthritis.
According to the United Nations Environment Programme (UNEP), AMR could shave off USD 3.4 trillion from global annual GDP and push 24 million more people into extreme poverty in the next decade. The UNEP also warns that by 2050, up to 10 million deaths could occur annually due to drug-resistant infections globally.
The misuse of antimicrobials extends beyond humans, affecting food-producing animals and aquaculture. The widespread use of these drugs to promote growth and prevent disease has led to resistant bacterial strains that can spread to humans through direct contact, consumption, or the environment.
While AMR drivers are universal, its impact is disproportionately severe in low- and middle-income countries, as noted by the WHO. Here, the overuse of non-prescribed drugs is more prevalent, exacerbating existing inequalities as healthcare costs rise and agricultural productivity falls.
Recognising the gravity of AMR, scientists and policymakers advocate for a multi-faceted approach. Improved surveillance is crucial, as highlighted by the United States Library of Medicine. Gaps in data on key microbes hinder our understanding of AMR trends, making it essential to establish standardised methods and definitions for tracking resistance.
Hospitals must improve infection control measures, while public education campaigns can help curb antimicrobial misuse. The Federation of European Microbiological Societies (FEMS) suggests that effective public awareness campaigns could cut antimicrobial prescriptions by 36%.
In agriculture, reducing antimicrobial use in livestock and developing new drugs to combat superbugs is imperative. The UNEP emphasises the environment's role in AMR's evolution and spread, advocating for a 'One Health' approach that recognises the interconnectedness of humans, animals, plants, and ecosystems.
For the 'One Health' strategy to succeed, global organisations and governments must prioritise AMR as an international concern. The time has come to place this threat at the forefront of the global political agenda, acknowledging that addressing AMR is not just a scientific or medical issue but a societal imperative that demands coordinated action from all sectors. Only by acting decisively can we hope to avert the looming health crisis and safeguard future generations from the devastating impact of drug-resistant infections.
The journey of Tilapia from miracle fish to ecological menace in Indian waters
Before becoming an aquaculture consultant and probiotic shrimp supplier, Apuchand Eluri farmed fish for 15 years on his 130-acre farm in Khammam district, Telangana. Today, an uninvited guest threatens to upend his livelihood.
"Tilapia feed much faster than the Carp because there are more of them, and they are very active feeders. They have robust spines on their fins, which prevent other fish from attacking them and eating the feed. They're more dominating and territorial. They eat the feed first, and the other cultured fish eat the rest," he said.
Tilapia, once hailed as a potential solution to global food security, has become both a blessing and a curse for Indian fish farmers and ecosystems alike.
In 1988, WorldFish and its partners started the Genetic Improvement of Farmed Tilapia (GIFT) project to develop a faster-growing strain of Nile Tilapia fit for small-scale and commercial aquaculture. According to the Consortium of International Agricultural Research Centers (CGIAR), GIFT has since become a lifeline for small-scale farmers, providing a sustainable source of income, food, and nutrition while helping them adapt to climate change.
A 2022 study by WorldFish and the Confederation of Indian Industry (CII) revealed a growing interest in Tilapia farming across India's eastern, western, and southern states. This trend is driven by rising prices of Carp and sea catch. India's current Tilapia production stands at approximately 70,000 metric tons, with 30,000 metric tons from aquaculture and 40,000 metric tons from wild catches.
The CII study projects India's Tilapia market to grow to over 0.766 million metric tons by 2027 and exceed 2.155 million metric tons by 2032. This aquatic chicken, as it's sometimes called, could significantly boost India's ambitious fish export goals.
Globally, Tilapia farming has grown much faster than the aquaculture sector and other farmed aquatic species categories over the last twenty years. But In Andhra Pradesh, India's aquaculture hub, the Tilapia boom feels more like a bust.
“Carps fetch anywhere between Rs 80 to Rs 100 per kg. But Tilapias fetch around Rs 10 to Rs 20 per kg, but their feed costs as much as the Carp. In Kerala, a fish called pearl spot or Etroplus, a close cousin of Tilapia, fetches almost 300 to 450 rupees per kg because of its taste,” said Eluri.
Eluri suffered significant losses due to the Tilapia invasion. To cut losses, farmers like Eluri have become creative, using dried and pulverised Tilapia as fish feed and soil fertiliser or selling it to Sea Bass farms.
Getting rid of Tilapia also proves challenging. “The bigger fish are caught in the nets; however, mid-sized and small fish hide in the soil at the uneven pond bottom. Even if the pond is dried, there will be some eggs or small fish in the slush. They start multiplying once the water fills the pond," he said.
India has a diverse palate. Proper planning is needed because a single species or strategy across the country may not be effective.
KK Vijayan, Former Director of the Central Institute of Brackishwater Aquaculture (ICAR-CIBA) Chennai and Former Head of the Marine Biotech Division, ICAR-CMFRI, Kochi, said Tilapia is not a one-size-fits-all solution. "India has a diverse palate. Proper planning is needed because a single species or strategy across the country may not be effective,” he said.
Tilapia that grows in brackish water are tastier and have more nutritional value as their bodies release a burst of antioxidants to counteract the salinity stress, he added.
A 2021 study found the Mozambique Tilapia to be the most extensively distributed invasive fish in the region. In just two years, their population in the Yamuna River jumped from a fraction to 3.5% of total fish species. In Rajasthan's Jaisamand Lake, they've reduced the average weight of major Carp and threatened endangered Mahseers. Tilapias have infiltrated biodiversity hotspots like the Andaman Islands and the Western Ghats and are thriving in the marine environment in Palk Bay, Tamil Nadu.
According to Smrithy Raj, a postdoctoral fellow at the University of Kerala and one of the study's authors, the Western Ghats contain more than 300 species of freshwater fish, of which nearly 70% are endemic. Roughly one-third are threatened by flow regulation, pollution, invasive species, climate change, and overexploitation.
“And among these, biological invasion is the most rapid and widespread. When there are a lot of new invasive species coming in, there is a higher chance that some species in the wild will die out,” he said. Raj said the number of non-native exotic species in the Western Ghats has doubled after the floods.
“Earlier, only the Mozambique Tilapia variety was found, but at present, Nile Tilapia has become dominant in the water bodies. They compete with native fish species for food and shelter. The Pearlspot Cichlid (Etroplus suratensis), Kerala's state fish, is at high risk due to the invasion of Tilapia, as both species share a similar niche,” he added.
Tilapia farming also has its own set of challenges.
An expert from the Indian Council of Agricultural Research (ICAR) said Tilapia can meet the protein demand and is very easy to grow, which is why it is being promoted worldwide. However, the highly contagious Tilapia Lake virus, which causes sudden mortality in Tilapia, is a cause for concern.
According to Vijayan, to achieve a blue revolution, the government should focus on various fish species instead of a single species. “Tilapia has its market niche, depending on various factors. We could take a holistic approach based on consumption patterns. Understanding these consumption patterns and marketing strategies is crucial,” he said.
Meanwhile, Eluri said the government intervention is unwieldy.
“Mozambique Tilapia is a wild species, but the government is promoting the genetically modified variety (GIFT), which grows to a larger size. However, because the Mozambique Tilapia has been around for decades, people have developed an aversion towards the fish. As a result, even if farmers want to culture GIFT, there are no buyers.” he said.
In the end, the Tilapia dilemma is more than just a question of fish farming—it's a test of our ability to balance progress with preservation, innovation with tradition, and short-term gains with long-term sustainability.
Find out which street foods might be dangerous and how to stay safe
In India, street food is more than just food; it’s an adventure. Whether you’re looking for a quick bite or an excuse to hang out with friends, these food stalls have you covered.
The famous Khau Gallis of Aamchi Mumbai are packed with hungry office workers and students ready to dive into a feast of pani puri, momos, and shawarmas. Meanwhile, Manek Chowk in Ahmedabad undergoes a nightly transformation from a bustling jewellery market to a food paradise, where scores of workers grate cheese with mechanical dedication, infusing it into everything from sandwiches to 'gotala' dosas. In Namma Bengaluru, the famous Rameshwaram Café takes pride in injecting its offerings with heart-stopping quantities of ghee.
The smells, the flavours, the sheer joy of eating something delicious right off the cart is what makes street food so irresistible. But beneath all that flavour, these snacks often conceal serious public health risks. Recent studies have given us more reasons to pause and reconsider our love for these quick bites.
{{marquee}}
Recent sampling in Karnataka found cancer-causing chemicals used as food colouring in many pani puri samples. Colours like sunset yellow, brilliant blue, and carmoisine, found in 19 out of 49 tested samples in Bengaluru, have raised health concerns. Officials are considering bans on these additives, but pani puri has long been a concern due to the water used, which is often contaminated and of uncertain origin. And it's not just pani puri. Kebabs were previously under scrutiny for artificial coloring use, while rhodamine-B, a dye found in Gobi Manchurian and cotton candy, caused health scares earlier this year. Shawarmas have also been flagged for safety concerns. A survey by the Food Safety and Standards Authority of India (FSSAI) across 10 districts in Karnataka revealed that 8 out of 17 samples contained harmful bacteria and yeast, which could cause severe illnesses like diarrhea, food poisoning, and pneumonia.
While many are aware of the risks associated with street food, the severity is often underestimated. Contaminants are not always visible, and one frequent yet overlooked danger is the use of newspapers to wrap food. Ink from newspapers can leach bioactive elements into food, posing serious health risks. If the newspaper is made from recycled paper, there’s the additional danger of metal contaminants and other harmful chemicals.
And then there is hygiene, a question almost entirely ignored in India’s street food culture. A 2023 study in Kolkata found that only a quarter of food vendors covered their food after preparation, leaving it vulnerable to airborne contaminants. Almost half reused leftovers from the previous day, increasing the risk of infection and foodborne illnesses.
While government authorities strive to regulate and enforce bans on harmful substances in street foods, these measures take time and are not always consistently applied. As consumers, it's essential to exercise caution. When indulging in street food, consider asking vendors about their water sources, consulting locals for trusted stalls, and opting for fried foods to minimize risk.
Alternatively, there are plenty of healthy snack options to enjoy. A mixed bowl of nuts like almonds, pistachios, cashews, and peanuts offers healthy fats, protein, and fiber without the risk of illness. Dark chocolate, rich in antioxidants, is another tasty choice. Fresh fruits also make a satisfying and nutritious addition to your snack repertoire.
