21st century's epidemic.

This is obscene in so far as still so many people die by starvation.
I think it is not so much a problem caused by eating too much, but by eating too damaging kinds of nutrition, and industrially ruined ("refined")food. having become a bordelrine case of index 25 myself over the last couple of years, I found a diet focussing on avoiding hyper-glycaemic carbonhydrates and trying to focus on hypoglycaemic carbonhydrates instead to be - by far - the most effectice and least fun-killing way to eat.
Which does not mean that I do not accept to occasionally "sin".
The follow-up costs of this epidemic for the health care system will reach stellar dimensions, and will make it bending.
