Why do I need to drink more water if I eat more fibre?

fibras2Soluble fibre dissolves in water a lot easier than insoluble fibre, for this reason it needs more water for its consumption. Soluble fibre forms several types of viscous gels which regulate the intestinal transit, but if excessively consumed, it may cause flatulence. On the other hand, insoluble fibre swells up as a sponge in order to absorb water, it enlarges faecal matter and favours intestinal transit.

If we increase our fibre intake, we should drink at least 1 or 2 litres of mineral water throughout the day, whether we are thirsty or not, between meals but never right after a meal. We also add water to our diet when we eat fruits or fruit juices, as well as vegetable soups, milk, yogurts, tea, infusions, etc.

Nevertheless, excessive water consumption may be harmful to our health, since it may cause our potassium and salt levels to drop, originating dizziness and fatigue. If our urine is light yellow in colour, it is a good sign that we are drinking the right amount of water.
