For generations, Indian households intuitively understood the value of fermented foods. Curd, buttermilk, kanji—these were not dietary trends but daily habits. Modern science has now given these traditions a name: gut health.

What is less widely known is that the gut plays a central role in immunity, metabolism, and even mental well-being. Disturbances in gut microbes—caused by poor diet, excessive antibiotics, and stress—are increasingly linked to lifestyle disorders such as diabetes and obesity.

As educators, we often tell students that prevention is better than cure. Probiotics represent exactly that philosophy. However, not all probiotic products are equally effective. Many fail to survive the harsh conditions of the stomach.

Recent advances in biotechnology, including protective formulations, have improved the survival and effectiveness of beneficial microbes. These developments are especially relevant for India, where non-communicable diseases are rising at an alarming rate.

Institutions such as Indian Council of Medical Research have repeatedly emphasized the importance of nutrition-based preventive strategies. Yet, public awareness remains limited.Gut health should not be viewed as an alternative or fashionable concept. It is mainstream science. Strengthening it through informed dietary choices and evidence-based products could reduce long-term healthcare burdens significantly.

Sometimes, progress does not come from new medicines but from understanding the body better—and working with it rather than against it.
