Is meat really the problem here?...
Yes and no. the "problem" with animal protien today is a product of the food industry,not nature. animals fed corn, wheat and soy and kept alive( because they are toxic to animals too) by hormones and antibiotics just long enough to make slaughter. So in it's current form(your corner market) Animal protein and farmed fish are not healthy.
That said, Range -free poultry grass fed beef and other protien sources are perfectly fine.(i didn't say easy to find)
The enemy here is not food, it's "food Products". Eat real food.
Our paleo ancestors didn't pick "vegan tofu burgers" from a tree. they ate plants, insects and animals-probably in that order, not because they preferred it but because that's what was available. Our genetic blueprint is omnivore.
While the Agricultural revolution is unquestionably responsible for our cultural advances a a species, our poor genes never adapted to the changes. Egyptian mummies show the first known cases of Diabetes and Tooth decay
Michael Pollan has two brilliant books on the subject -"the Omnivore's dilemma
and " In Defense of Food: An Eater’s Manifesto"
Michael Pollan - In Defense of Food
Some tips that come to mind: If your Great Grandmother wouldn't recocgnize it as food, don't eat it.
If it doesn't go bad--don't eat it( for instance, you could will a box of Twinkies to your children and the expiration date would still be good)
If it has More than five ingredients..stay away
If it contains high fructose corn syrup...welcome to hell..I mean the western diet.
Eat Food.-REAL food (see above)
Mostly plants. Not too much
My experiences show me that works
