This is fascinating. I live in the U.S. and I can't drink any kind of alcohol, nor consume any processed foods, whatsoever without getting an autoimmune reaction which, until I figured out what was going on, almost killed me. The only thing which saved me from dying was going on a 100% raw food diet -- NOT vegan or vegetarian, but similar to raw ketogenic or raw paleo diets.
A friend of mine recently went to Spain and she said she was shocked that the people there were not overweight and sickly looking as they often are in the U.S. ...even though it appeared to her that they ate the same foods.
