Your ancestors were meat eaters and we’re not just talking about Grampa on the farm 50 years ago. Scientists date meat consumption by our human ancestors to somewhere around 1.5 million years ago. The Paleo Diet, Atkins Diet, and most other nutritionally complete eating plans all include meat. “Don’t you want to know why”, to quote Strother Martin in Butch Cassidy and the Sundance Kid? Those guys were all meat eaters, by the way. If you’re a millenial and haven’t seen this movie, you need to. Order up a pepperoni and sausage pizza (with lots of veggies, too), invite your friends, and sit back and enjoy a classic flick this weekend.
Now, back to the subject at hand…. why we need to eat meat. Humans are not able to synthesize all of the necessary amino acids required to build proteins in our bodies. We get those essential nutrients from eating meat. Plant based diets just aren’t complete in our amino acid requirements. Taking it a step further, a study of our monogastric stomach system proves that we are not capable of digesting high fiber plant foods like ruminants do (i.e. cows, buffalo, deer, sheep, goats, antelope, for examples). We aren’t designed to graze! If you, or someone you know, is following a current vegetarian eating plan, we hope you will delve deeper into the nutritional soundness and not just be a follower of a modern day food fad. 1.5 million years of bbq just can’t be all wrong.
