Why Can’t Indians Digest Dairy Like Before? Expert Explains This Changing Gut Story

For generations, India has been a land of milk lovers. A glass of milk before bed, curd with every meal, ghee on rotis, paneer in celebrations - dairy wasn't just food; it was comfort, culture, and calcium. But somewhere between our grandparents' childhoods and today's busy metros, something has changed.

More and more Indians now say, "Milk doesn't suit me," or "Curd gives me bloating," or the dramatic classic: "Paneer betrayed me." Why is our gut suddenly protesting the very foods we grew up eating?

We spoke to Dr Akash Chaudhary, Clinical Director and Senior Consultant Medical Gastroenterology, CARE Hospitals, Banjara Hills, Hyderabad, who explained why some people cannot digest dairy products.

Your Gut Has Changed - Literally

"Our digestive system is not a fixed machine. It shifts depending on our lifestyle, environment, antibiotics, and even stress levels. One of the key players in this process is lactase, the enzyme that helps break down lactose in milk, explained Dr Chaudhary.

He added, "In many Indian adults, lactase production naturally declines after adolescence. Earlier, this decline didn't bother us much because our traditional diets supported good gut bacteria that helped compensate. But today's lifestyle has other plans."

What Changed? More Than You'd Think

Here are some quiet disruptors that have altered how Indians digest dairy:

Antibiotics (especially childhood courses)

Repeated antibiotic use wipes out gut bacteria that aid lactose digestion. Many parents don't realise how much this can affect their child years later.

Modern, processed diets

Chips, packaged snacks, sugary drinks feed the "bad" bacteria; they are not the ones that break down dairy.

Sedentary lifestyle

Less movement slows down digestion overall, making heavy dairy feel harder on the gut.

Change in milk quality

Urban families often consume milk from mixed breeds, long-storage packets, or ultra-pasteurised cartons, all of which taste fine but digest differently than fresh, local milk.

Stress (yes, stress hits digestion too!)

High cortisol weakens gut motility and enzyme production. A stressed stomach is a sensitive stomach.

It's Not Always Lactose - Sometimes It's Inflammation

For some people, it's not lactose intolerance at all. It's low-grade gut inflammation, often driven by:

  • Irregular meal timings
  • Late dinners
  • Fast-food-heavy weeks
  • Lack of fermented foods
  • Poor sleep

When the gut lining is irritated, even a simple glass of milk can feel like a burden.

The North-South Difference

"Interestingly, many South Indians tolerate curd but not milk, while many North Indians tolerate milk but struggle with curd. Regional food traditions shaped gut bacteria over generations, and modern diets are disrupting that balance," explained Dr Chaudhary.

What Actually Helps?

You don't have to 'give up milk forever.' A few small resets often fix the problem:

  • Switch to curd, chaas, paneer, and ghee; they're easier to digest.
  • Try smaller servings instead of big glasses of milk.
  • Add fermented foods like idli-dosa batter, homemade pickles, and kanji to rebuild gut bacteria.
  • Give your gut a breather by avoiding dairy on days your stomach feels off.
  • Move a little after meals to improve digestion.

Your Gut Isn't Weak - It's Adapting

Dr Chaudhary concluded, "India's dairy story is not ending; it's simply evolving. As our lifestyles shift, our gut microbes shift with them. Tuning in to these changes and adjusting our habits can bring dairy back into our lives; maybe in smaller, smarter, more traditional ways."
