A practical, low-FODMAP diet chart for Indians living with IBS — foods that are usually well tolerated, common trigger foods, a sample day plan and tips to manage flare-ups.
If certain everyday Indian foods — dal, onions, wheat, milk — seem to set off bloating, cramping or unpredictable bowel movements, you may be dealing with Irritable Bowel Syndrome (IBS). This guide explains what IBS actually is, how a low-FODMAP approach works with Indian food, and gives you a realistic sample day to reduce flare-ups without giving up your favourite meals for good.
Irritable Bowel Syndrome (IBS) is a common functional gut disorder — meaning the gut doesn't work quite right, even though standard tests usually don't show any structural disease or damage. It is diagnosed by a doctor based on recurring abdominal pain that is related to bowel movements, along with a change in stool frequency or form, occurring on average at least once a week over the past three months. IBS is different from conditions like ulcerative colitis or celiac disease, though your doctor may run tests to rule these out.
Common symptoms include abdominal pain or cramping (often relieved after passing stool), bloating and visible abdominal distension, excess gas, and changed bowel habits. IBS is generally grouped into three types based on the predominant pattern:
| Type | Main pattern |
|---|---|
| IBS-C | Constipation-predominant — infrequent, hard stools |
| IBS-D | Diarrhoea-predominant — frequent, loose or urgent stools |
| IBS-M | Mixed — alternating between constipation and diarrhoea |
FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides And Polyols — short-chain carbohydrates that are poorly absorbed in the small intestine. In sensitive people, these carbs get fermented by gut bacteria, drawing in water and gas, which can trigger the pain, bloating and irregular bowel habits typical of IBS. A low-FODMAP diet temporarily reduces these foods to calm symptoms, then reintroduces them one group at a time to identify your personal triggers — it is not meant to be a permanent, ultra-restrictive diet.
These foods are generally better tolerated and can form the base of your meals, especially during a flare-up.
You do not need to avoid these forever — the goal is to identify which ones actually trigger your symptoms during a supervised reintroduction phase.
Not everyone reacts to every high-FODMAP food. Many people with IBS tolerate small portions of trigger foods just fine — it is usually the quantity and combination, not one single ingredient, that causes a flare.
This is a general low-FODMAP-style template for a calmer gut day — adjust portions and specific foods based on what you personally tolerate.
| Meal & time | What to eat |
|---|---|
| Early morning · 7:00 AM | 1 glass warm water; ginger tea if preferred |
| Breakfast · 8:30 AM | Plain poha or rice-flour dosa with light tempering (no onion-garlic), small portion |
| Mid-morning · 11:00 AM | 1 small ripe banana or a few orange segments |
| Lunch · 1:30 PM | Rice or 1 roti + small portion moong dal + carrot-cucumber salad + boiled potato sabzi |
| Evening · 4:30 PM | Ginger tea + a few rice crackers or roasted makhana |
| Dinner · 7:30 PM | Rice or khichdi with light vegetables (no onion-garlic), grilled fish or egg if non-vegetarian |
A structured low-FODMAP approach has three phases. First, an elimination phase of about 2 to 6 weeks where high-FODMAP foods are reduced to calm symptoms. Second, a reintroduction phase where each FODMAP group (like onion-garlic, or dairy, or certain legumes) is tested one at a time to see what actually triggers your symptoms. Third, a personalisation phase where you build a longer-term diet that avoids only your specific triggers rather than everything. This process works best with a dietitian's guidance, since doing it alone often leads to unnecessarily restrictive eating.
For IBS-C, gradually increasing soluble fibre (oats, isabgol if advised) and fluid intake, along with regular movement, often helps with constipation; insoluble fibre like wheat bran can sometimes worsen symptoms, so introduce fibre slowly. For IBS-D, smaller meals, limiting caffeine and very fatty or fried food, and staying hydrated with electrolytes during loose motions can help. For IBS-M, tracking your food and symptom pattern in a diary is especially useful, since triggers and helpful foods can vary week to week. In all types, a qualified dietitian can help fine-tune fibre type and quantity to your specific pattern.
See a doctor to confirm an IBS diagnosis before starting a restrictive diet, since other conditions can cause similar symptoms. Seek prompt medical attention if you notice red-flag symptoms such as unintentional weight loss, blood in the stool, persistent fever, anaemia, symptoms starting after age 50, or a family history of colon cancer or inflammatory bowel disease — these need proper medical evaluation rather than self-managed dietary changes alone.

Explore the Diploma in Nutrition →IBS (Irritable Bowel Syndrome) is a specific, doctor-diagnosed functional gut disorder involving recurring abdominal pain linked to changes in bowel habits over at least 3 months. General gut health issues can include occasional bloating, acidity or irregularity without meeting these criteria. If symptoms are frequent or affect daily life, see a doctor to confirm an IBS diagnosis before starting a restrictive diet.
Dal is not inherently bad, but many dals and legumes are high-FODMAP in large portions because they contain fermentable oligosaccharides that can trigger gas and bloating in sensitive people. Smaller, well-cooked portions of dals like moong dal are usually better tolerated than large servings of rajma or chana.
Yes. Rice is low-FODMAP and is one of the most IBS-friendly staples in an Indian diet. Plain rice, rice-based idli, dosa and poha are usually well tolerated and are a good base for meals during a flare-up.
A low-FODMAP diet is meant to be short-term: typically 2 to 6 weeks of elimination, followed by a structured reintroduction of foods one group at a time to identify your specific triggers. It is not meant to be followed strictly forever and is best done with guidance from a dietitian.
It depends on the person. Curd contains lactose, a common IBS trigger, but its live cultures can help some people. Many with IBS tolerate a small bowl of fresh curd better than milk; if symptoms worsen after dairy, a lactose-free or plant-based alternative may help.
Common Indian food triggers include large portions of onion and garlic, excess oil and fried food, very spicy dishes, carbonated and caffeinated drinks, large helpings of certain dals and legumes, some fruits eaten in excess, and artificial sweeteners in sugar-free products.
