It’s time to get back to my 44 pages of notes from the McDougall Advanced Study weekend. I totally need to refresh my mind on everything. So where shall we start…? Oh, yes, proteins!
Much of the discussion on protein came from my nutrition idol, T. Colin Campbell, PhD. As you all know, I think everyone should read “The China Study”, and you will never look at animal protein quite the same. And for those of you more science-minded, there’s his book “Whole” that gives you the science behind why animal protein is bad for you.
In “The China Study”, the largest ever nutritional study (hundreds of thousands of people in the study), Dr. Campbell proved the link between animal protein and cancer. By adding and removing animal protein, he could turn cancer cells on and off. This was the key reason why I gave up eating meat (and am working on removing all dairy and eggs).
There are more details in the books, obviously, but in a nutshell, animal protein impacts the initiation of cancer, as well as the promotion of cancer cells. It lowers natural killer cell activity, increases cell replication, and increases oxygen radicals, to name a few of the impacts. When the animal protein level is too high, it causes a lot of things to go wrong.
The first study linking animal protein to heart disease occurred in 1905!!! That’s over 100 years ago! Incredible that it is taking us all so long to learn this message (well, I guess we aren’t really learning this still). There have been many more studies since then proving this linkage, but the power of advertising is apparently stronger than the power of scientific evidence.
The minimum daily requirement for protein is 6-7% of daily calories, the recommended daily allowance (the “optimal” amount) is 8-9%, and the average American is consuming 17-18%.
The nutrient composition of animals versus plants is also an issue. Plants contain antioxidants, complex carbohydrates, and vitamins and minerals. When you eat animal protein instead of plant protein, it’s a double whammy. You get too much protein and not enough of the nutrients that you need.
