While we may be familiar with the dangers of a poor diet, in particular eating too much sugar, the actual effects of this may be far more frightening than previously imagined. Certainly, science supports the idea that excess sugar consumption leads to weight gain, increasing our chances of becoming obese as well as developing diabetes and heart disease. But now, new data shows that sugar can harm us in a place we didn’t expect, by actually attacking our DNA. Majority of the world’s population will average around 13-14% of calories a day from pure added sugar. It would seem we’re destined to harm our DNA.
