If cane sugar is the worst “natural” sweetener, why was diabetes so rare before the sudden increase of diabetes in the 20th century?

Answer 1

Explanation for a 5yr old: it isn’t that cane sugar is always bad. It’s the amount of cane sugar, or other sugars, that can be bad. Eating a little cane sugar won’t give you diabetes or cause Type 1 to give you problems, but a lot and often can.
