Now, he’s shared what happens to the gut if not enough water is consumed when eating fibre.
And it could “wreck” your body completely, reports What’s The Jam.

“However, if you don’t drink enough water with it, it makes a concrete-like substance in your colon and can make your constipation worse.”
He urges people when eating fibrous diets to consume at least eight cups of water per day, otherwise there’s a risk that digestion will slow down.
Dr Sethi added, “A good rule? Your wee should be pale yellow.
