Hi Guys,
As I understand it (and I may be wrong) the theory behind a dairy free diet is as follows:
We don't know exactly why some of us develop cancers while others do not. The precise causes remain a mystery, however there is circumstantial evidence that suggests diet might have something to do with it?
Following on from Jane's Plants observation that there is much less breast and prostate cancer in east asian cultures that enjoy dairy free diets, we look at dairy food as a possible culprit?
What is apparent is that humans have evolved to grow relatively slowly, in a wild world at times of danger our mothers would pick us up and run, so we didn't need to be too heavy. However four legged animals cannot do this, a calf needs to be on its feet and ready to run away under its own steam as fast as possible.
Consequently cows milk contains many more growth hormones than mothers milk, and a calf will double in weight twice as fast as a human baby.
So when you consume dairy products from cattle you are consuming a supercharged product with lots more growth hormones that your human body was designed to deal with.
It might, and it is a big MIGHT, be these extra strong growth hormones that cause cancer to develop in the first place, or allow tumours to grow so fast once established. Especially when we know that elimination of hormones in Hormone therapy stops, or at least delays, growth of the cancer.
So far as I know this theory applies equally to goats, sheep and cows milk.
