Passing wind is a normal part of digestion, although that does not make it any less awkward when it is painful or happens at the wrong moment. Gas comes from swallowed air and from gut bacteria fermenting parts of food that we don't fully digest. Portion size, eating speed, fizzy drinks and sudden changes in fibre can all influence it.
Beans, lentils, whole grains and brassica vegetables often get the blame, but removing them all can make constipation worse and reduce the variety in your diet. Try smaller portions first, rinse tinned pulses and increase fibre gradually. Eating more slowly and noticing whether fizzy drinks or chewing gum add to the problem can help too.
Please speak to your GP if wind comes with persistent pain, blood in your stool, unexplained weight loss or a lasting change in bowel habit. If IBS is suspected, a dietitian can guide any elimination and reintroduction rather than leaving you with an unnecessarily narrow diet.
Begin with a smaller serving of beans or lentils and increase it gradually. Rinsing tinned pulses removes some surface salt and liquid, and some people find it improves comfort.
Dried beans should be soaked and cooked according to their instructions. Undercooked pulses can cause illness as well as digestive discomfort, so this is not a place to shorten the cooking time.
Start with a small portion of a pulse you enjoy; tolerance varies by type and amount.
Try a smaller serving of hummus if a full portion feels uncomfortable.
Increase pulse portions gradually rather than following a fixed timetable.
Broccoli, cabbage and other brassicas can increase gas, particularly in large raw portions. Smaller servings cooked until tender may be easier while still keeping useful vegetables in the diet.
Onion and garlic are also common triggers for people with IBS. Garlic-infused oil can provide flavour during a supervised low-FODMAP phase, but broad restriction is unnecessary for people who tolerate them.
Cook broccoli and cabbage thoroughly - raw brassicas bother some guts more.
Onion and garlic are common triggers - garlic-infused oil may help in IBS under dietitian advice.
Portion size: a mountain of cauliflower rice is not the same as a side serving.
Fizzy drinks and eating speed
Fizzy drinks add swallowed gas directly, while chewing gum, rushing meals and talking with food in the mouth can increase swallowed air. These habits are worth testing before removing several nutritious foods.
Try sitting for one meal, slowing the first few mouthfuls and replacing one carbonated drink with still water. This is a mechanical experiment, not a mindfulness performance.
Swap one fizzy drink for still water or squash and see whether symptoms change.
Slow down one meal and notice whether swallowing less air helps.
A short gentle walk after a meal may feel comfortable for some people, but it is not a guaranteed remedy.
IBS sometimes responds to a short dietitian-led low-FODMAP process, but that should include reintroduction. Many people can bring back smaller portions of pulses or other foods once their individual tolerance is understood.

Keep fibre in the budget plan
Removing beans entirely may reduce fibre, fullness and affordable protein. Adjust the portion and frequency before deciding they cannot be part of your diet.
Combine a smaller amount of pulses with rice, frozen vegetables and another tolerated protein. This keeps the meal satisfying while the digestive system adapts.
Increase portions at a pace that suits your symptoms.
Rinse tinned pulses if you prefer, while remembering that portion size may matter more.
Keep tolerated fibre foods in the week rather than cutting every possible trigger.
Seek medical advice for a persistent change in bowel habit, blood in the stool, unexplained weight loss, anaemia, fever, significant pain or symptoms that wake you at night. New symptoms later in life also deserve assessment.
A brief food and symptom diary can help, particularly when it records portion size and timing. Wind after an unusually large bean meal is different from a lasting unexplained change.
