I cut back my sugar intake for half a year (bread, chocolate, sodas, etc.) and felt worse, my digestion becoming more erratic and irregular. Right now, I am enjoying a couple of pieces of delicious chocolate while laughing about the people who demonize certain classes of food. We know embarrassingly little about our digestion. Who knows, in 30 years we will say proteins are the devil and then we go back to hating fats. You have to go absolutely crazy on sugars to cause diabetes. We are talking about 'regularly skipping meals and then compensating by eating a couple of chocolate bars' crazy.
