Yes, the mandate from the nutritional guidelines is 60% of the diet to be carbs. That's what is safe. What's a carb? Molecules of glucose liked together. When the links are broke you end up with 60% of your diet being sugar.

Fun fact: This guidelines didn't change since 1974, with the creation of the food pyramid. Who created the food pyramid? Look it up! A cooperative of supermarkets in Sweeden with the mandate of reducing inflation.

Since the instauration of this guidelines all chronical desises skyrocketed: diabetes, heart attacks, overweight, metabolic syndrome etc etc. If they recognize their mistake, they will be recognizing the biggest crime against humanity in history.
