this fear mongering is not kosher, warren buffet has 5 cokes a day.
he has the best health care in the world and doesn't suffer like the poor from diet coke, but he still drinks 5 cokes a day and is healthy as a horse for a 90 year old man.
the lesson here is if you eat and drink bad, you must take personal responsibility.
for example, if you eat a lot exercise a lot to manage it.
