Is sugar a drug?
Is sugar a drug? Most of us will say no. You get it from grocery store, put it in your food (or get them from food unknowingly) and it seems much more harmless than drugs.

Our brains are hardwired to prefer sweet food for evolutionary reasons. But we are facing the opposite problem now. Overdose on sugar can cause weight gain, diabetes, heart disease, cancer, etc. And they are hidden everywhere, pasta sauce, milk, granola, you name it!
