You decide to eat more fibre, so breakfast becomes bran cereal, lunch becomes a large bean salad and dinner gets an extra helping of vegetables. Then your stomach feels different, and you wonder whether the new foods are the problem.
Sometimes the pace of change matters. A sudden increase in fibre can bring gas, bloating or other digestive discomfort. That doesn’t mean every fibre-containing food needs to disappear from your meals.
Change one part of the day Start with a manageable addition, such as some oats at breakfast or a small serving of beans with a meal. Give yourself time to see how it suits you before changing several other things.
This is easier to understand than adding a cereal, a supplement and several new foods on the same day. If you feel uncomfortable, you’ll have a clearer idea of what changed.
Include a range of foods Wholegrains, vegetables, fruit, beans and nuts can contribute fibre. Choose foods you enjoy and can prepare regularly, taking allergies and any dietary advice into account.
You don’t need to rely on one heavily promoted ingredient. Ordinary foods can play a part, and packaged products can be compared using their labels.
Keep fluids in the picture Fluids help fibre work in the digestive system. Keep drinks available during the day rather than adding more fibre and forgetting to drink.
If you have been told to limit fluids, follow your care team’s instructions. Ask for advice that takes both your food and fluid needs into account.
Don’t explain away ongoing symptoms Fibre isn’t the answer to every digestive problem. Get medical advice for persistent symptoms, and seek prompt care for severe abdominal pain, vomiting or blood in your stool.
A clinician or dietitian can help you decide what amount and types of food suit you, including whether a supplement has any role. For your next meal, focus on one reasonable change rather than trying to make up for everything at once.
