To begin with, diabetes is a condition where the body can't control the amount of glucose (or sugar) in the blood, and if left untreated, it can cause many complications like heart attack, stroke, kidney failure and blindness.
Diabetes International Federation, which is in Belgium, says that an estimated 415 million people have diabetes worldwide. In fact, in Mexico sugary drinks have decreased in sales because of the sugar tax, measure which has actually worked so far.
