"SIBO is not a life sentence of dietary restriction. It is a temporary condition that requires a structured elimination phase, targeted treatment, and a systematic reintroduction - not permanent fear of food." - Dt. Trishala Goswami, MSc Clinical Nutritionist

The short answer: a SIBO diet for Indians is a temporary low-FODMAP version of normal Indian food, followed for about 4 to 8 weeks alongside the treatment your doctor prescribes. Rice, poha, jowar, eggs, chicken, fish, ghee, gourd vegetables and most spices are usually fine. Onion, garlic, wheat, rajma, chole, milk, cauliflower and mango are paused, then brought back one at a time. Diet eases the symptoms; it does not clear the overgrowth on its own.

"I cannot eat dal. I cannot eat onion or garlic. Roti makes me bloat. Rice makes me bloat. What exactly am I supposed to eat?" I hear some version of this from almost every client who arrives with a SIBO diagnosis and a generic low-FODMAP list written for Western kitchens. They look at the "avoid" column and see most of what they cook.

It does not have to be that way. Indian food has more SIBO-friendly options than most lists suggest, and the restrictive phase is short. Below is the food list I use with clients, the swaps that keep meals recognisably Indian, a sample day, and the order in which foods come back.

The Indian SIBO Food List

Use this during the low-FODMAP phase. "Usually fine" means most people with SIBO tolerate a normal portion. "Small portions" means a measured amount is usually tolerated but a large one may not be. "Avoid for now" means pause it until you reach reintroduction.

The guidance follows Monash University's published FODMAP testing where a food has been lab-tested. Foods marked with an asterisk (*) have not been lab-tested; their guidance comes from clinical experience. Monash updates serving sizes as it re-tests foods, and your own tolerance may differ, so treat this as a starting point.

Grains and starches

Food	During the low-FODMAP phase	Notes
Basmati rice, white or brown rice	Usually fine	The safest grain for most Indian SIBO clients
Poha*	Usually fine	Skip the onion; use peanuts, curry leaves and lemon
Jowar (sorghum) flour, bajra (millet), buckwheat (kuttu)	Usually fine	Good roti alternatives to wheat
Oats	Small portions	Up to half a cup of rolled oats
Quinoa, potato, sabudana (tapioca)	Usually fine	Sabudana khichdi without onion works well
Sweet potato	Small portions	About half a cup
Idli, rice dosa	Small portions	The urad dal in the batter contains fermentable carbohydrates; 2 idlis are usually tolerated
Ragi, besan	Small portions	Not lab-tested; start with one ragi roti or a thin besan chilla
Wheat roti, paratha, naan, bread, biscuits	Avoid for now	Wheat is high in fructans; reintroduce later

Dals, pulses and protein

Food	During the low-FODMAP phase	Notes
Eggs, chicken, fish, mutton	Usually fine	Protein foods contain no FODMAPs; watch the onion-garlic masala
Firm tofu, tempeh	Usually fine	Silken tofu is high in FODMAPs
Paneer	Small portions	About 40 g a serving; paneer has more lactose than hard cheese
Moong sprouts*	Small portions	Long-tailed bean sprouts are lab-tested as low FODMAP; home-sprouted whole moong is not, so start with a small bowl, lightly steamed
Masoor dal, split moong dal*	Small portions	A few spoonfuls, well rinsed and well cooked; cooked red lentils are low FODMAP only in small amounts
Toor, chana dal, urad dal	Avoid for now	Higher in galacto-oligosaccharides
Rajma, chole, lobia, roasted chana	Avoid for now	Among the last foods to reintroduce

Dairy, fats and oils

Food	During the low-FODMAP phase	Notes
Ghee, butter	Usually fine	Almost no lactose
Mustard, coconut, groundnut, olive oil	Usually fine	Garlic-infused oil gives garlic flavour without the fructans
Hard cheese	Usually fine	Cheddar and parmesan are very low in lactose
Curd (dahi)	Small portions	1 to 2 tablespoons, or use lactose-free curd; a full bowl carries a lot of lactose
Chaas (buttermilk)*	Small portions	One small glass of thin, well-diluted chaas
Coconut milk (canned)	Small portions	About a quarter cup (60 g) per serving; larger amounts are high in sorbitol. Skip brands with added inulin (chicory root)
Milk, khoya, most mithai	Avoid for now	Lactose-free milk is a good swap for chai

Vegetables

Food	During the low-FODMAP phase	Notes
Lauki, tori, parwal, tinda*	Usually fine	The backbone of SIBO-friendly sabzis
Spinach, carrot, tomato, cucumber, capsicum	Usually fine
Brinjal (baingan), green beans, pumpkin (kaddu)	Usually fine
Cabbage (patta gobhi)	Usually fine	Common cabbage is low in FODMAPs at about three-quarters of a cup
Methi leaves*	Usually fine	Cooked into sabzi
Bhindi, broccoli florets, sweet corn	Small portions	About half a cup
Green peas (matar)	Small portions	About 2 tablespoons; larger amounts are high in galacto-oligosaccharides
Spring onion greens	Usually fine	Only the green tops; the white bulb is high in fructans
Cauliflower (phool gobhi), mushrooms	Avoid for now	High in polyols
Onion, garlic	Avoid for now	Replace with hing, ginger, spring onion greens and garlic-infused oil

Fruits

Food	During the low-FODMAP phase	Notes
Papaya, orange, kiwi, grapes, pineapple, strawberries	Usually fine	One portion at a time, not a fruit platter
Banana	Small portions	One firm, just-yellow banana; a ripe, spotty banana is low FODMAP only at about a third, as fructans build up
Pomegranate	Small portions	About a quarter cup of seeds
Mango, apple, pear, watermelon	Avoid for now	High in fructose or polyols
Dates, figs, raisins	Avoid for now	High in fructans at usual portions

Nuts, seeds and snacks

Food	During the low-FODMAP phase	Notes
Peanuts, walnuts	Usually fine	A small handful
Pumpkin, sesame, chia and flax seeds	Usually fine	1 to 2 tablespoons
Almonds	Small portions	Up to 10
Makhana*	Small portions	Not lab-tested; a small bowl, roasted in ghee, is usually tolerated
Cashews, pistachios	Avoid for now	High in fermentable carbohydrates

Flavourings and drinks

Food	During the low-FODMAP phase	Notes
Ginger, turmeric, jeera, coriander, mustard seeds, curry leaves, black pepper, green chilli, mint, lemon	Usually fine
Hing (asafoetida)	Usually fine	A pinch; many brands contain wheat flour, so choose a gluten-free one if you have coeliac disease
Ready masala mixes, garlic or onion powder	Avoid for now	Check labels for onion and garlic
Weak tea, black coffee	Usually fine	Make chai with lactose-free milk
Coconut water	Small portions	One small glass; large glasses carry more sorbitol and fructans
Honey	Small portions	One teaspoon at most; larger amounts are high in excess fructose. Plain sugar is better tolerated

What Is SIBO?

Small intestinal bacterial overgrowth (SIBO) means too many bacteria are living in the small intestine, which normally holds relatively few. These bacteria ferment carbohydrates before the body has absorbed them, producing hydrogen, methane or hydrogen sulfide gas. The result is bloating, abdominal pain, gas, and diarrhoea, constipation or both. Over time, SIBO can interfere with the absorption of vitamin B12, iron and fat-soluble vitamins.

SIBO overlaps heavily with irritable bowel syndrome (IBS). An early study by Pimentel and colleagues (2000) found abnormal breath tests in 78% of 202 IBS patients. A larger 2018 meta-analysis of 50 studies (Chen and colleagues, Journal of Gastroenterology) put the pooled figure at 38%, which is still more than a third of people with IBS. If you have been told you have IBS and diet changes have not helped, SIBO is worth asking your doctor about. Our IBS diet plan for Indians covers the overlap.

How SIBO Is Diagnosed and Treated

Diagnosis. The standard test is a glucose or lactulose breath test. You drink a sugar solution and breathe into tubes every 15 to 20 minutes for about 2 hours. A rise in hydrogen or methane points to bacterial fermentation in the small intestine. In India, breath testing is available through gastroenterology departments and specialty labs in most large cities.

The breath test also tells you which type you have:

Hydrogen-dominant SIBO usually causes diarrhoea and gas soon after eating.
Methane-dominant overgrowth, now called intestinal methanogen overgrowth (IMO), usually causes constipation.
Hydrogen sulfide SIBO is newer, needs a specialised three-gas breath test, and is linked with diarrhoea and very foul-smelling gas.

Treatment. SIBO is treated by your doctor. The American College of Gastroenterology's 2020 guideline suggests a course of antibiotics for people with symptoms; rifaximin is the one most often used. The low-FODMAP diet runs alongside treatment to reduce symptoms; it does not clear the overgrowth by itself. Because SIBO often returns, the underlying cause (slow gut movement, previous surgery, some medicines) also needs attention.

See a doctor promptly if you have blood in your stool, unintended weight loss, symptoms that wake you at night, persistent vomiting, or new gut symptoms after the age of 50. These need investigation before any diet plan.

Why Indian Food Is Tricky With SIBO

FODMAPs are fermentable carbohydrates, and they are the fuel the overgrown bacteria use. Many Indian staples are rich in them:

Fructans: wheat (roti, paratha, naan), onion and garlic, which go into almost every Indian dish.
Galacto-oligosaccharides: rajma, chole, lobia and most dals.
Lactose: milk, khoya and most mithai.
Polyols: cauliflower, mushrooms, apples and pears.
Excess fructose: mango, honey and watermelon.

The low-FODMAP diet itself is well studied in IBS. In a randomised crossover trial of 30 people with IBS by Halmos and colleagues (2014, Gastroenterology), symptoms were clearly lower on a low-FODMAP diet than on a typical Australian diet. The work for an Indian kitchen is translation: keeping the flavour and structure of the meal while changing the ingredients that carry FODMAPs.

Indian Swaps That Keep Meals Familiar

Instead of	Use during the low-FODMAP phase
Onion and garlic in the tadka	Hing, ginger, spring onion greens and garlic-infused oil (fry garlic in oil, then remove it)
Wheat roti	Jowar or bajra roti, rice, or a rice-flour roti
Rajma or chole	Eggs, paneer, firm tofu, or a few spoonfuls of masoor dal
Milk chai	Chai with lactose-free milk, or black tea with lemon and ginger
Cauliflower or mushroom sabzi	Lauki, tori, cabbage, beans or palak
Mango or apple	Papaya, orange, kiwi or a firm banana
Store-bought masala	Whole spices you grind yourself

A Sample Indian SIBO Day

Early morning: warm water with lemon and a pinch of ginger.

Breakfast: 2 idlis or a rice dosa with coconut chutney made without onion (fresh coconut, roasted chana dal, ginger, green chilli, curry leaves). Or poha with peanuts and curry leaves, or a 2-egg bhurji with tomato and ginger.

Mid-morning: a bowl of papaya with a spoon of pumpkin seeds.

Lunch: one katori of basmati rice, lauki or tori sabzi with a hing and jeera tadka, a few spoonfuls of masoor or split moong dal, and a cucumber, tomato and carrot salad with lemon.

Evening: a small glass of thin chaas with roasted jeera, or a small bowl of makhana roasted in ghee.

Dinner: jowar roti with palak sabzi and 1 to 2 tablespoons of curd (or a bowl of lactose-free curd), or egg curry in a tomato and ginger base with rice.

It is not festive food, but it is familiar, filling and nutritionally complete. If you also have diabetes, the rice and fruit portions need adjusting; our guide to managing a low-FODMAP diet with diabetes explains where the two plans conflict and which rule to follow.

Bringing Foods Back: The Reintroduction Plan

The low-FODMAP phase usually lasts 4 to 8 weeks, matched to your treatment. After that, foods come back one group at a time so you learn your own limits. This is the order I use with clients:

Weeks 1 to 2: wheat. Start with half a small roti. If you feel fine after 48 hours, try a full roti, then two.
Weeks 3 to 4: dals. Begin with a larger serving of masoor or moong dal than you had during the low-FODMAP phase, then try toor and chana dal. Rajma and chole come last.
Weeks 5 to 6: onion and garlic. Start with a little cooked onion. Raw onion is usually the last to be tolerated.
Weeks 7 to 8: the rest. Cauliflower, mushrooms, milk, mango and apple.

Test one food group at a time and leave 48 hours between tests. Tolerance depends on the amount, so you may handle a little onion but not a lot. The goal is the widest possible diet with the fewest symptoms. Most people with treated SIBO eventually eat most foods in moderate amounts, and staying on a strict low-FODMAP diet long term is neither necessary nor good for your gut bacteria. Our guide to the best Indian foods for gut health covers what to rebuild with afterwards.

The Elemental Diet: For Severe or Recurrent SIBO

When SIBO keeps returning despite treatment, a doctor may suggest an elemental diet: a pre-digested liquid formula taken instead of all food for 2 to 3 weeks. Because it is absorbed high in the small intestine, it leaves little for the bacteria to ferment. In a study by Pimentel and colleagues (2004, Digestive Diseases and Sciences), 74 of 93 patients (80%) had a normal breath test after 14 days on an elemental diet.

It is hard to follow and is not a first step. In my practice I reserve it for clients who have not responded to two or more rounds of treatment. It should only be done under the supervision of a doctor or dietitian experienced with SIBO; homemade versions from online recipes can leave you short of nutrients.

Key Takeaways

A SIBO diet for Indians is a temporary low-FODMAP version of normal Indian food, used for 4 to 8 weeks alongside medical treatment.
Rice, jowar, bajra, eggs, chicken, fish, ghee, gourd vegetables, papaya and most spices are usually fine.
Onion, garlic, wheat, rajma, chole, milk, cauliflower and mango are paused, not banned.
Curd, dal, coconut milk, paneer and almonds work in measured portions.
Diet eases symptoms; treatment from your doctor clears the overgrowth.
Bring foods back one group at a time to find your own limits.

Frequently asked questions

Is rice good for SIBO?

Yes. White and brown rice are low in FODMAPs and are the most reliable grain for most people with SIBO. Basmati rice is usually the easiest to tolerate. Poha is generally fine too; keep idli and rice dosa to small portions, because the batter contains urad dal. Eat rice with a protein and a gourd vegetable rather than on its own, and keep portions measured if you also have diabetes.

Is curd (dahi) good for SIBO?

In small amounts. Fermentation lowers the lactose in curd, but a full bowl still contains enough to trigger symptoms in many people. During the low-FODMAP phase, keep curd to 1 to 2 tablespoons, choose lactose-free curd, or have a small glass of thin chaas. If lactose is not a problem for you, you can bring larger portions back during reintroduction.

Is ghee OK for SIBO?

Yes. Ghee is almost pure fat with negligible lactose, so it contains no FODMAPs. It is a good way to add flavour once onion and garlic are off the menu. Keep the overall amount moderate, as very fatty meals can worsen symptoms in some people.

Is coconut milk good for SIBO?

In moderation. Monash University's current testing puts canned coconut milk as low FODMAP at about a quarter cup (60 g) per serving. Larger amounts contain more sorbitol, which can cause symptoms, and brands with added inulin (chicory root) are high FODMAP, so check the label. Coconut chutney made from fresh coconut without onion is usually well tolerated.

Can I eat dal with SIBO?

A few spoonfuls of well-rinsed, well-cooked masoor or split moong dal are usually tolerated; cooked red lentils are low FODMAP only in small amounts, so keep it a side, not the main dish. Toor, chana and urad dal, and whole pulses like rajma and chole, are higher in fermentable carbohydrates and are best paused until reintroduction. Eggs, paneer, tofu, chicken and fish can cover your protein in the meantime.

Are jowar, bajra and makhana low FODMAP?

Jowar and bajra, yes. Monash University lists sorghum flour and millet as low FODMAP, so jowar and bajra rotis are good alternatives while wheat is paused. Ragi and makhana (fox nuts) have not been lab-tested, so start with one ragi roti or a small bowl of makhana and see how you feel. Our [guide to ragi, jowar and bajra](/blog/ragi-jowar-bajra-indian-millets-guide) explains how to cook with them.

Is papaya good for SIBO?

Yes. Papaya is low in FODMAPs and usually well tolerated, which makes it one of the best fruit choices during the low-FODMAP phase. Orange, kiwi, grapes and a firm banana are also good options. Have one portion of fruit at a time rather than several fruits together.

Which vegetables and spices are safe with SIBO?

Lauki, tori, parwal, brinjal (baingan), spinach, carrot, tomato, cucumber, capsicum and green beans are all usually fine, and common cabbage is fine at about three-quarters of a cup. Most whole spices, including black pepper, jeera, turmeric, ginger and a pinch of hing, are low in FODMAPs. Onion, garlic, cauliflower, mushrooms and ready masala mixes are the ones to pause.

How long should I follow a SIBO diet?

Usually 4 to 8 weeks, alongside treatment, followed by a structured reintroduction over the next 6 to 8 weeks. A strict low-FODMAP diet is not meant to be permanent. If symptoms persist after treatment and reintroduction, go back to your doctor, as SIBO can recur and the underlying cause may need attention.
