Gut Health, the Indian Way
The Supplement I Almost Bought
A shop assistant once tried to sell me a probiotic capsule for eleven hundred rupees a month. Forty billion cultures, eight strains, imported.
I went home, opened my fridge, and looked at a bowl of homemade curd.
Our food culture has been doing this for centuries — curd with every meal, idli and dosa batter left to ferment overnight, kanji in winter, pickles, buttermilk in summer, dhokla, appam. We were eating live cultures long before anyone thought to put them in a capsule and price them accordingly.
I am not against supplements. But before spending on one, it is worth knowing that the tools are already in the kitchen — and they come with fibre, protein and actual meals attached.
Why the Gut Matters More Than I Realised
There are roughly as many bacterial cells in your gut as there are human cells in your body — something like 38 trillion organisms, collectively weighing about 2 kg.
What they do reaches further than digestion.
They produce vitamins, including vitamin K and several B vitamins.
They influence how much you extract from food. Two people eating the same meal do not necessarily absorb the same amount from it.
They regulate a large share of immune function — roughly 70% of immune tissue sits around the gut.
They affect mood. Around 90% of the body's serotonin is produced in the gut, and the gut-brain axis is now a serious field of research rather than a fringe idea.
They affect appetite and fat storage. Gut composition differs measurably between lean and obese people, though the direction of cause and effect is still being worked out.
What this meant practically for me: bloating, irregularity and the general heaviness I had accepted as normal were not inevitable. They were feedback.
Probiotics and Prebiotics — the Difference
These two words get used interchangeably in marketing and they are not the same thing.
Probiotics are the bacteria themselves. Live cultures you eat.
Prebiotics are what those bacteria eat — specific fibres that feed the good bacteria already living in you.
Probiotics without prebiotics is like releasing fish into a tank with no food. Most people focus entirely on the first and ignore the second, which is why the expensive capsule often does less than expected.
Indian probiotic foods
- Fresh homemade curd — the most reliable one available to us
- Buttermilk and chaas
- Idli and dosa batter, naturally fermented overnight
- Dhokla and khaman
- Kanji — the black carrot drink made in winter
- Traditional oil-and-salt pickles, genuinely fermented rather than vinegar-based
- Appam, and fermented rice dishes from the south and east
Indian prebiotic foods
- Raw and cooked onion and garlic — among the richest sources anywhere
- Bananas, especially slightly underripe
- Whole pulses and legumes
- Oats, barley, jowar, bajra and ragi
- Flaxseed
- Cooked and cooled rice or potato — cooling creates resistant starch, which is excellent prebiotic material. This is the quiet advantage of curd rice and of yesterday's rice eaten cold with curd.
The Fibre Problem
If probiotics get all the attention, fibre is where the actual gap is.
The recommendation is around 30-35 g a day. Average urban Indian intake has fallen to somewhere near 15 g, largely because of the shift from whole grains to refined flour and polished rice.
When I counted mine, I was at about 14 g. Correcting it did more for my digestion than any other single change.
How I got from 14 g to 32 g
- Switched from maida-based breakfasts to oats — 4 g
- One extra katori of dal or whole pulses daily — 6 g
- Bajra or jowar roti in place of wheat, three days a week — 3 g
- A salad with lunch and dinner — 5 g
- Fruit with the skin on, rather than juice — 4 g
Two warnings, both learned the hard way. Increase fibre gradually, over two to three weeks — going from 14 g to 35 g overnight produces spectacular bloating and will convince you that fibre disagrees with you. And fibre without water makes constipation worse, not better. If you increase one, you must increase the other.
What Damages the Gut
Worth knowing, because adding good things while continuing the damage does not get you far.
Antibiotics. Necessary when they are necessary, and genuinely disruptive — a single course can alter gut composition for months. The problem in India is how casually they are taken for ordinary viral fevers, where they do nothing at all. If you must take a course, curd and fermented foods afterwards help recovery, though the evidence on timing is still developing.
Highly processed food. Emulsifiers and artificial sweeteners in particular appear to affect gut bacteria unfavourably in the research so far.
Chronic stress. The gut-brain axis runs both ways. Sustained stress measurably changes gut composition and motility.
Too little sleep. Gut bacteria follow a daily rhythm too, and irregular sleep disrupts it.
Eating the same five things forever. Diversity of plants is one of the strongest predictors of a healthy gut in the research. The often-quoted target is 30 different plant foods a week — and that counts every grain, pulse, nut, seed, herb and spice, so it is far more achievable in an Indian kitchen than it sounds. Rotating dals alone gets you a good part of the way.
What I Actually Do
Nothing exotic, and nothing that costs eleven hundred rupees a month.
Curd or buttermilk daily, homemade where possible. Set at home it costs almost nothing and has no added sugar, unlike most flavoured shop varieties — which frequently contain more sugar than a biscuit.
Onion and garlic in most cooking, which I was doing anyway and did not realise was doing double duty.
Dal or whole pulses every single day, rotated through the week rather than the same one repeatedly.
Millets several times a week — bajra, jowar and ragi in place of wheat.
Fruit whole, never as juice. Juice removes the fibre and leaves the sugar.
A ten-minute walk after dinner, which helps motility more than people expect.
Jeera, saunf, ajwain and hing in normal cooking. Our traditional digestive spices are not folklore — they have measurable carminative effects, which is presumably why they ended up in the food in the first place.
A closing caveat: persistent bloating, pain, or a real change in bowel habits is a reason to see a doctor, not to add more curd. This is my experience and my reading, not medical advice. But for the ordinary sluggishness that many of us have quietly accepted as normal, the fix was mostly fibre, water and food we already know how to make.
