Years ago I met with some people who had studied, I think it was called macrobiotics?, anyways, DNA, genetics, and food.
I am Anishnaabe/Lakota and my ancestors relied on meat consumption, fresh fruit, greens, never drank milk from other animals, etc.
For a short period of time I had the money to be able to eat strawberries, blueberries, rasberries, moose meat, turtle, elk, caribou, bear, several types of greens, etc. All plants and animals indigenous to my area. I swear that is the one time in my life I felt like Superwoman! :LOL No allergies, no colds, no flus, my muscle mass increased without much work on my part(never had a gym membership), I built my own canoe and paddled and paddled, tapped for maple syrup, walked everywhere, etc. That was the best two years of my life.
