While the lifestyle of veganism is on the rise, there is still a large number of people who do not relate the reasons behind people becoming vegans.

So why is the veganism hype not affecting those who do not want to cease consuming meat? One, because humans evolved to eat meat and two, because it is unhealthy to not consume animal products.

Christopher Wanjek, an editor from The Washington Post has a lot to say about why calling vegan diets “natural” is an overstatement. “In terms of evolution, being able to cooking food is what made us human.” The argument that is made in terms of evolution is that it would have been unlikely for humans to have evolved a large brain on vegan diet alone and that meat consumption was an essential part of human evolution since millions of years ago. National Academy of Sciences posted a study where they examined the brain size of several primates. The study came to a conclusion that larger bodies equalled to larger brains; however, humans had large, neuron-rich brains for their body size. The big conflict of this study was why humans had bigger brains compared to gorillas, that are three times bigger than humans. The study concluded that it was because of gorillas’ raw, vegan diet. “Adding neurons to the primate brain comes at a fixed cost of approximately six calories per billion neurons. For gorillas to evolve a humanlike brain, they would need an additional 733 calories a day, which would require two more hours of feeding.”

Why is plant-based diet unrealistic? Humans are omnivores, meaning humans thrive by eating both animals and plants. Not consuming meat can come with a few consequences such as vitamin B12 deficiency, weak bones and muscles, and lack of creatine. Vitamin B12 is only found in meat and is critical for life. According to Authority Nutrition, B12 is the most important nutrient that vegans should be concerned with, yet 92% of vegans struggle with obtaining this vitamin. Healthy muscles and bones come from obtaining essential amino acids in the correct ratios and animal protein is what aids in healthy muscles and bone development/maintenance. Creatine is a protein compound that helps form energy reservoir in cells. A study suggests that lack of creatine can cause harm on muscle and brain function.
