A friend just sent me this article
Dirty Secrets of the Food Processing Industry: http://www.westonaprice.org/modernfood/dirty-secrets.html
Scariest article I read in a long time. I hope it's not all true. "The rats that received the whole wheat lived over a year on this diet. The rats that got nothing but water and vitamins lived about two months. The animals on water alone lived about a month. But the company's own laboratory study showed that the rats given the vitamins, water and all the puffed wheat they wanted died within two weeks---they died before the rats that got no food at all. It wasn't a matter of the rats dying of malnutrition. Autopsy revealed dysfunction of the pancreas, liver and kidneys and degeneration of the nerves of the spine, all signs of insulin shock."
and "But the rats receiving the corn flakes and water died before the rats that were eating the box! (The last corn flake rat died the day the first box rat died.)"
Also there was a good article on cod liver oil from the same web site.
