"Gut health" has become a popular phrase, often attached to expensive supplements. Yet many traditional Indian foods already support the gut: curd, buttermilk, idli and dosa, kanji, dhokla, pulses, millets and a wide variety of vegetables. Research on the gut is still developing, so it is wise to be cautious about big promises. What is well established is that a diet rich in fibre and varied plant foods supports regular digestion and overall health.

What we mean by gut health

The gut, especially the large intestine, is home to trillions of bacteria and other microbes, often called the gut microbiome. They help break down fibre and produce substances the body can use. A varied diet with plenty of fibre gives these microbes a range of foods, and fibre is closely linked to better bowel health.

Pillar 1: Fibre from many plant foods

Fibre is the main food for gut microbes. Indian sources include:

  • Pulses: rajma, chana, moong, masoor, toor, lobia.

  • Whole grains and millets: whole wheat, brown rice, jowar, bajra, ragi, oats, dalia.

  • Vegetables: leafy greens, beans, bhindi, gourds, carrots, cabbage.

  • Fruit: guava, banana, papaya, apple, orange.

  • Nuts and seeds: peanuts, almonds, flax, til.

Pillar 2: Fermented foods

Fermentation is old Indian kitchen wisdom. Many fermented foods contain live microbes when freshly made, and fermentation can also make some nutrients easier to absorb.

  • Curd and buttermilk: set at home from milk.

  • Idli, dosa, appam and dhokla: made from fermented rice and lentil batters. Cooking reduces live microbes, but fermentation changes the food in useful ways.

  • Kanji: a fermented drink, often made from black carrots in North India.

  • Pickled vegetables: traditional fermented pickles, eaten in small amounts because they are usually high in salt and oil.

Curd and buttermilk are the easiest daily options. Evidence for specific health effects of each fermented food varies, so treat them as part of a balanced diet rather than as medicine.

Pillar 3: Variety

Different plant foods feed different microbes. Aim for variety across the week:

  • Rotate dals and legumes.

  • Change vegetables with the season.

  • Mix grains: wheat, rice and millets.

  • Add herbs and spices such as jeera, ajwain, ginger, turmeric and coriander, which also add flavour without extra salt.

A simple goal is to eat many different plant foods each week, counting each vegetable, fruit, pulse, grain, nut and seed.

A gut-friendly day

  • Breakfast: idli with vegetable sambar, or vegetable dalia with a bowl of curd.

  • Lunch: rajma or chana with brown rice, a mixed vegetable sabzi and salad.

  • Snack: a guava or banana and a glass of buttermilk.

  • Dinner: millet roti, moong dal and a leafy green sabzi.

This one day includes pulses, two kinds of whole grain, several vegetables, fruit and a fermented dairy food.

Habits that support digestion

  • Eat at regular times.

  • Chew well and eat slowly; see mindful eating.

  • Drink enough water, especially as you increase fibre.

  • Stay active; walking after meals helps many people feel comfortable.

  • Get enough sleep.

  • Keep highly processed foods, sugary drinks and fried snacks occasional.

Food safety with fermented foods

Home fermentation should be clean. Use clean utensils, keep curd and batters covered, and discard anything that smells unusual, grows coloured mould or tastes very off. Clean handling is what prevents illness.

Probiotic and prebiotic supplements

Supplements may help in some specific situations, such as after certain illnesses or treatments, but they are not needed by most healthy people eating a varied diet. Ask a doctor before using them, especially if you have a weakened immune system.

A note on safety

Persistent bloating, pain, changes in bowel habits, blood in stools, unexplained weight loss or ongoing diarrhoea or constipation need a doctor's assessment. People with irritable bowel syndrome may need a specific plan from a dietitian. See our medical disclaimer.

Frequently asked questions

Is curd good for gut health?

Curd is a traditional fermented food that is easy to include daily. It also provides protein and calcium.

Do idli and dosa contain probiotics?

The batter is fermented, but cooking reduces the live microbes. They are still nourishing, easy-to-digest foods.

Should I take a probiotic supplement?

Most healthy people do not need one. Ask a doctor if you have a specific reason to consider it.

Key takeaways

Support your gut with plenty of fibre from pulses, whole grains, vegetables and fruit, include curd or buttermilk daily, enjoy traditional fermented foods, and aim for variety. For a varied weekly plan, try the free assessment.
