Acutally,food problems come from Industrialization, GMF,chemical additive etc. Our ancestors never heard of that.

I believe diabetes is a disease from sugar imbalance. Many foods in industrialized countries are processed and have sugar added which can cause health problems when eaten in excess. Obesity is probably the biggest health problem as far as America goes. There is a large push in recent years to get children to eat more healthy foods instead of junk food.

Yes many people suffer from lactose and wheat intolerance due to all the chemicals added to milk and bread. Others have fructose malabsorption which means they can't tolerate foods containing too much sugar like pears, apples, beetroot, green beans etc.Some little kids are allergic to peanuts or eggs. Takeaway food often contains bacteria because it has been handled incorrectly or handled by people who are ill or haven't washed their hands. Companies have been fined for adding harmful ingredients to their products which have poisoned many people.
