I don’t claim to know the underlying science but if we could get away with having that much sugar in our diets, I would be surprised. It seems the big sugar companies have been putting pressure on the World Health Organization not to preach that sugar should be no more than 10% of one’s diet. Mind you, I can’t see how an ordinary person can tell just what percentage sugar is in anything you eat – apparently this means “don’t eat sugar more than four times a day” – but what about fizzy drinks? What about food that contains some sugar but isn’t sweet per se?
Anyway, it seems from the subsequent WHO press release they were not intimidated.
