Fibre Guide: Dietary fibre is essential for healthy digestion, balanced blood sugar and heart health. Dr Saurabh Sethi, a gut health specialist, has highlighted top fibre-rich foods such as chia seeds, flax seeds and lentils. These foods nourish beneficial gut bacteria and support overall wellbeing. White bread ranks poorly due to the refining process, which removes much of its fibre. Prioritising whole, plant-based foods is an effective way to increase daily fibre intake.
