The last to be concerned about with the American diet is the amount of meat.
It is the high sodium, high sugar and highly processed franken-food.
That is what is killing everybody, what has caused such dramatic increases in diabetes and heart disease.
Actually the amount of meat eaten is a factor in heart disease
Not nearly too the extent of high sodium/sugar.
Our bodies are designed to process meat. Sure, it was never meant to process two big macs for lunch, a steak for dinner and bacon for breakfast, and then sit around and watch TV all day - but that is not a reasonable amount.
Diet is about moderation and balance... including meat. As well as caloric intake, and how active you are.
Look at the folks who live in the extreme north, they live on a high-high fat diet with a LOT of meat. And they have less problems than we do. But they are also 3 times as active and their bodies burn a ton calories staying warm.
Actually we are far closer to gorillas in our digestive system than to lions.
And if you want to talk about evolution then you have to take into account that humans ate far less meat than they do today and that meat was all wild game and nothing like the overly fattened, steroid and antibiotic ridden meats of today
Bu the fact remains that meat is not a neceesary part of a healthy diet
Wrong again.
Humans would never have evolved to be what we are if we maintained a plant based diet.
The fact we evolved with vastly superior intelligence is because we ate meat.
The more intelligent a being is, the more protein and carbohydrates it needs to function properly.
Again, that doesn't mean one needs to eat 2000 calories of meat a day by any stretch, but the fact is meat is an outstanding source of protein as well as the pleasure of eating it is scientifically proven to improve our moods.
Meat is good for you. In moderation, and combined with a healthy balance of vegetables and fruits.
Saying otherwise is just dumb.
