medical testing proved a man can live on 12 ounces of any food....meat sandwhiches, pizza, etc.....they didn't care what food it was. one doctor lived many/many years in perfect health and weighed his food every day, not to exceed 12 ounces.
you will find food is all about fear, little more.
the oldest author i had a book on was age 110 and he never mentioned he changed his bad diet. walker i understand lived past age 110 and lived on fruit/vegetable juices...but when it is all over with, it will be "fear" that determined what foods were bad or good for people.
the problem is all with the "mind"
eating food is a brain washing affair that effects us all.
