The trouble with Michael Mosley and his ilk is that they make their dough out of making us a bit more anxious about our diet and our gut. Anyone who is heading for gut trouble should consult their doctor. The telly doctors and the pushers of fad diets know nothing about you and your particular circumstances. Much of Michael's advice is undoubtedly good, but it can't be prescriptive for you. Overall good advice about healthy eating, the Mediterranean diet, etc., can't be bad, but the obstinate fact is that he doesn't know you and your condition.   We should always beware of any medical or dietary "advice" proffered by members of internet forums. Interesting reading is one thing, and can inform us. Generic advice is entirely a different matter.
