Humans are physiologically, mentally, and physically made to eat meat. If you are a vegetarian, I hope you think twice before trying to change a meat eater’s mind about their steak dinner. These are just the facts – believe them or not. Humans, in general, are omnivores, and I can prove it.
Historically, humans have been natural meat eaters. Why do you think meat tastes so good to us? It’s because our species has evolved to eat it. According to National Geographic, “We have an improved ability to process cholesterol and fat.” Ninety-eight percent of the world eats meat, and it tastes good to most of us because chemicals are released in our brain that tell our body it’s good.
Switching to meat gave our ancestors an advantage. Researchers at the University of Southern California have found that when ancient humans began to consume meat 2.5 million years ago, they gained access to a new source of protein that helped produce larger brains and superior intelligence. Where would we be if we hadn’t discovered the first steak?
Secondly, humans are physiologically designed to eat meat. We need the protein, iron, and nutrients that only meat can provide. Without it, we face the risk of inadequate vitamin and mineral levels. As omnivores, our bodies are designed to process both meat and plant matter. According to TIME online, “a quarter-pound of meat stimulates almost twice as much gastric juices as does a quarter-pound of carbohydrates, and is correspondingly better for normal digestion.” We may not have teeth like a cat that can shear a deer, or an intestinal track that allows us to eat raw meat, but we have the single-chambered stomach common to carnivores and omnivores. Herbivores, on the other hand, have multiple stomach chambers. Humans find cellulose (the main component of plant tissue) totally indigestible, while we digest meat quickly and efficiently.
Lastly, people who choose not to eat meat do not reach their physical peak. UK Cohort hosted a study of 3,086 meat-eating women and 593 non-meat-eating women. The non-meat eaters had significantly lower levels of energy, protein, zinc, and fats than meat eaters. In the TV series “The Truth About Food,” professional athletes (both vegetarians and meat eaters) were studied as they changed their regular diet. The vegetarian athletes ate meat two times a day, while the meat-eating athletes consumed only carbs and vegetables. Colin Jackson, a former world-champion sprinter and hurdler, said that he felt “physically weaker” after not eating meat for a month.
Eating meat is what people are supposed to do. We as a species are smarter, healthier, stronger, and more developed since we began to eat meat. Why would you want to change that?
