Foreigners

Eat like the French or Japenese or Greeks or Italians. Most foreign traditional food cultures eat healthy than Americans.
The traditional western diet is the most unhealthy of all food cultures. That says alot when we are so diverse in our food in America.

Once other countries are invaded by our fast foods, either in resturants or food markets they start having all the health problems of the United States.

So adopt one foreign food culture.
