Re: IQ and vegetarianism
Human beings are supposed to be herbovires. Look at the construction of their teeth..do they resemble with those of dogs, big cats/small cats or hyenas who sink their teeth into raw meat and rip it apart ?.
*Because of smart mental faculty humans devised ways of softening meat by roasting or boiling so that it becomes soft and hence easier to eat. *
Yet to meet a person who eats meat like a carnivore.
Like Fraudia said, we are OMNIVORES (Meat and Plant eaters).
Herbivores have flat teeth for grinding veg, we also have some sharp teeth for tearing into beef steak and beef burgers, if we don't eat meat we are denying ourselves essential proteins which are very hard to get from veg, our stomachs are perfectly capable of digesting both veg and meat, even certain uncooked meats such as rare beef steak for example.
