How should this fibre drink be taken, and how much liquid do I need to drink? — Fiber Health cocktail (turmeric/Jerusalem artichoke) 150g

Dietary fibre — including fibre from the wheat grain husk and inulin from Jerusalem artichoke — absorbs water and swells in the gastrointestinal tract. That is why drinking enough fluid throughout the day is not just a recommendation but a condition for the product to work properly. Without enough water, fibre can leave you feeling heavy rather than light.

If you have not eaten much fibre before, introduce the product gradually: start with a small amount and increase the portion over several days. This gives your gut time to adapt and reduces the likelihood of bloating or discomfort at the start.

The mix can be stirred into water, kefir or yoghurt, or added to porridge and smoothies — the main thing is that the total amount of liquid is sufficient. It can be taken at any time of day: some people prefer the morning so they stay full for longer, others take it before a main meal to reduce their appetite.

If you have sensitive digestion or a chronic gastrointestinal condition, or are pregnant or breastfeeding, it is worth consulting a specialist before use. The mix is based on wheat grain husk, so the product is not suitable for people with coeliac disease or a wheat allergy.
