Based on research and experience, I would say that the average diet in this country is a death sentence for millions of people. If you attempt to get all the vitamins and minerals you need from a normal American diet, you will not only suffer diseases needlessly, you will die several years before your time. To begin with, food derives its nutritional strength from the soil. But the mineral content of much of the nations's arable soil has been vastly reduced over the years by various factors, chief among which has been the continuous destruction of the land by insecticides and chemicals. The nutritional losses from modern methods of feeding livestock and poultry are even greater.
Washing food takes away many valuable minerals and vitamins which are on the skins and outer layers.
We must now consider the way we prepare the food after it comes home. The Cheraskin study show, that to get the nutrients your grandparents had, you would have to eat three or four times the amount of food they did, if supermarket food is your only source of nutrition.
