Re: IQ and vegetarianism
that is awesome link.
of course, more scientific research will conclusively show that it is true.
bio-chemically, the animal proteins, need fiber to metabolize.
as a diff species, we are similar in digestive systems to fauna. but, even four footed animals, much larger than us -elephants, giraffes, etc., with the exception of felines, thrive on vegetables and not dead meat of their preys.
for our biology as we know it, as humans, we definitely need flora as a regular and preferred content of our diet, to keep ourselves functioning at optimal levels.
furthermore, nutritional studies, and the food pyramid, shows that we must have a proportionate intake of meat, and not over eat meat for health reasons.
cognition and mental alertness comes with practice as well. but, intelligence theory does include the study of environmental and developmental growth factors including the positive effects of adequate diet as nourishment and the negative ones of mal nourishment, on the human brain to functioning
being a vegetarian, i can say, it makes a huge difference in one’s health.
