Which may explain why vegans are often mentally *off*! But no, really, with regard to how our brains "grew" to their present size, it is known that any mammal fetus requires protein for the development of the brain cells, and ONLY protein. The higher the protein content in a pregnant mammal's diet, the larger the brain of its offspring. Theoretically, when our ancestors "split" from chimps or apes and our diet changed to one of high protein (as in, meat!), pregnant females started "building" fetuses with larger brains.
Today, when you come across the very STUPID vegan woman who insists on keeping to a vegan diet while pregnant, what her body will do is to rob from her nutrients to "build" the baby. Hence pregnant vegan women are debilitated and weak during their pregnancies, and their babies are often underweight.
Makes sense. Very interesting -- "split from chimps." Didn't realize this.
Also read that our brain size is limited due to the size of the birth canal. And our brains might be much larger if it weren't for the fact that it would kill both mother and child during birth if the child's head were much larger.
Ask any mother -- it is tough enough as it is. :)
Vegans also have serious vitamin deficiencies, especially IIRC B12, which are directly related to brain function. Such deficiencies have symptoms similar to early onset senility.
Sounds like practicing veganism during pregnancy could be considered child abuse.
All we need to create some serious mischief are a few peer reviewed studies and someone to introduce the legislation.
; )
I'm vegan. I'm not stupid at all. Don't think all vegans are the way that PETA fanatics are.
