8. Humans aren’t built to eat meat
The film’s narrator, Kip, and Dr. Milton Mills attempt to make the case that humans are frugivores, animals that eat mostly fruit, based on anatomy. A major argument was that the canine teeth are useless at ripping and tearing animal flesh. Kip demonstrated this by playfully nuzzling his cat and it didn’t die. :/
If you lick your pet and it survives, you didn’t exactly prove you can’t kill an animal. There’s plenty of anthropological evidence that we’re meant to hunt in groups and use tools to get the job done. People have dextrous hands, weapons, and hunting buddies. We don’t need huge fangs.
Plus, humans have the digestive features of an omnivore:
- Your digestive tract lacks the enzymes and digestive structures of an herbivore, but our intestines are longer than those of a carnivore. Its structure indicates humans break down quick energy foods like plants and can also handle the longer breakdown requirements of animal proteins and fats.
- Your body doesn’t neutralize phytic acid from grains and legumes like herbivores do. This is a problem because phytic acid binds to minerals and keeps you from absorbing them. In this case, that means you aren’t getting much of the iron, zinc, and calcium from the grains and legumes you eat. Phytic acid will also bind to those three nutrients in any other veggies you eat alongside grains.
- Several nutrients are more bioavailable to humans from animal sources, such as protein, vitamin K, and omega-3 fatty acids.
Dr. Mills also supports his claim that we are natural vegans by pointing out that fish smoothies are unappetizing. Seems legit.
