“For humans, too much animal food is toxic.”
Eat to Live (p 83)
Dr. Joel Fuhrman
“Today the link between animal products and many different diseases is as strongly supported in the scientific literature as the link between cigarette smoking and lung cancer. For example, subjects who ate meat, including poultry and fish, were found to be twice as likely to develop dementia (loss of intellectual function with ageing) than their vegetarian counterparts in a carefully designed study.
The discrepancy was further widened when past meat consumption was taken into account. The same diet, loaded with animal products, that causes heart disease and cancer also causes most every other disease prevalent in America including kidney stones, renal insufficiency and renal failure, osteoporosis, uterine fibroids, hypertension, appendicitis, diverticulosis and thrombosis.”

‘… subjects who ate meat, including poultry and fish, were found to be twice as likely to develop dementia (loss of intellectual function with ageing) than their vegetarian counterparts in a carefully designed study.’
Well, this is radical.Every where I look, I see articles about how good fish is for brain and heart.This theory is based, as far as I know, on the health of people who eat mostly fish.
This statement, as far as I am aware, is based upon the results of T. Colin Campbell’s long term study in China when he correlated chronic health conditions with foods consumed in different regions. You can hear him answering questions on these topics at http://www.tcolincampbell.org/courses-resources/home/webinars/
He also covers this in full in his book, “The China Study”.

The study referred to in Dr Joel Fuhrman’s book “Eat to Live” when he states “subjects who ate meat, including poultry and fish, were found to be twice as likely to develop dementia (loss of intellectual function with ageing) than their vegetarian counterparts in a carefully designed study” is Glen, P.
