The Return Of Desi Cooling Foods And Why Your Gut Prefers Them

As

supermarket shelves fill up with probiotic drinks, kombucha cans, and 'gut-friendly' snacks, something far quieter is happening in Indian kitchens. The humble glass of chaas is back on the table and so is kanji. So are soaked sabja seeds, sattu, fermented rice, kokum sherbet, and bowls of cooling daliya. Foods once dismissed as 'old-fashioned' are suddenly being rediscovered by a generation struggling with bloating, acidity, poor digestion, and constant fatigue. And according to doctors and nutrition experts, this return to desi cooling foods is not nostalgia, actually, it is biology.

What Nutritionists Say

“There is a quiet but telling shift happening in how patients are relating to food again,” says Dr. A. Sangameswaran, Consultant - Gastroenterology & Hepatology, Apollo Speciality Hospitals, Vanagaram Chennai. “Traditionally, Indian households never needed a probiotic supplement. They had kanji, buttermilk, raw mango, kokum, and fermented rice doing that job every summer.”

For centuries, Indian households instinctively adjusted their diets with the seasons. Summer meals became lighter, more hydrating, and easier on the stomach. Buttermilk replaced heavy gravies. Water-rich fruits appeared on every plate. Fermented foods quietly nourished the gut long before the microbiome became a wellness buzzword. Now, modern science is beginning to validate what traditional food wisdom already understood. “What we are now understanding through microbiome research is that these weren’t just comfort foods; they were functional,” explains Dr. Sangameswaran. “The gut microbiome is deeply sensitive to heat stress, and many of these desi-cooling foods, high in natural prebiotics, live cultures, and anti-inflammatory compounds, actively buffer that response.”This matters more than ever in today’s eating landscape. Highly processed foods, refined sugars, preservatives, and irregular eating habits are increasingly linked to digestive issues. Many people live in a constant cycle of acidity, sluggish digestion, bloating, and inflammation without realising how disconnected their diets have become from their body’s natural rhythms. That is where traditional cooling foods seem to step in almost effortlessly.Dr. Anshul Singh, Team Lead- Clinical Nutrition & Dietics Dept, Artemis Hospitals, says these foods work because they are naturally aligned with what the body needs in extreme heat. “Desi cooling foods like curd, buttermilk, coconut water, soaked sabja seeds and seasonal fruits like watermelon and cucumber help in naturally regulating the body temperature,” he says. “But more importantly, they promote intestinal health.”

Curd and chaas, for example, are rich in probiotics, beneficial bacteria that support digestion and strengthen the gut lining. Ingredients commonly added to them, like cumin, mint, coriander, and black salt, do more than improve flavour. They actively reduce acidity, aid digestion, and help the body retain hydration. “They are light, hydrating and easy to digest compared to processed, heavy foods,” says Dr. Singh. “They help maintain healthy gut bacteria balance which is vital for overall health, including immunity and even mental health.”

What Research Says

That connection between the gut and the rest of the body is now impossible to ignore. Research increasingly shows that gut health influences not only digestion but also inflammation, immunity, mood, sleep, and energy levels. A disturbed gut microbiome can affect everything from skin health to stress response. Perhaps that is why many people feel unexpectedly better when they return to foods they grew up eating. Dr. Sangameswaran believes the body remembers. “What concerns me clinically is how quickly this knowledge gets displaced by packaged ‘gut health’ products that the body often doesn’t absorb as efficiently,” he says. “The gut has a memory, it responds better to foods it has co-evolved with over generations.”In hospitals too, he says the effects are visible. “When patients, especially those recovering from illness or on long-term medication, return to these traditional foods, we consistently see improvements in gut motility, reduced bloating, and better microbiome diversity. Science is finally catching up to what grandmothers already knew.” But the revival of traditional eating also comes with a modern complication.Mr. Prateek Rastogi, Co-Founder & CEO, Better Nutrition, points out that while the wisdom behind these foods remains strong, the nutritional quality of the ingredients themselves has changed over time. “India’s grandmothers did not call sattu and daliya ‘cooling foods.’ They simply called them dinner,” he says. “Seasonal eating was never a trend; it was ecology. The summer harvest and the body’s summer needs were, for centuries, in quiet agreement.” That agreement, however, has been disrupted by decades of soil depletion and intensive farming practices.

“The daliya on your morning table may look identical to your grandmother’s, but it delivers measurably less nutrition per bowl,” Rastogi explains. “Decades of intensive agriculture have left India’s soils deficient in zinc, iron, and other essential minerals. When the soil is depleted, so is the crop.” The consequences often appear subtly: constant tiredness, hair fall, low energy, dull skin, or nutrient deficiencies despite eating seemingly healthy meals. “The result is hidden hunger,” he says. “Not from eating badly, but from eating food that has quietly become weaker.” Still, experts insist the answer is not abandoning traditional foods in favour of imported superfoods or expensive supplements. Instead, it is about strengthening those traditions with better awareness and better-quality ingredients.“The fix is not to abandon tradition but to reinforce it,” says Rastogi. “Biofortified grain varieties bred to restore higher iron and zinc levels carry the same taste and cooling properties while closing the nutritional gap.” In many ways, the return of desi cooling foods reflects something bigger than a wellness trend. It signals a growing fatigue with overcomplicated health culture. After years of being sold powders, pills, and processed “health foods,” many people are rediscovering that the simplest answers were often sitting in steel tumblers and clay pots all along. Your gut, it turns out, may not be asking for the latest imported probiotic drink. It may simply want the foods it has understood for generations.Expert inputs by:Dr. A.
