Excessive protein according to Cheng et al. (2012) plays a role specifically in the woman’s body. It was shown that children with the highest intakes of animal or vegetable protein experience pubertal onset up to 7 months earlier. This is of particular importance because early onset of puberty is considered an intermediary factor to a number of adulthood diseases and hormone-related cancers.
What do you think of this? Is this a reason to go vegan (naturally consume less hormone loaded animal protiens)? How many beans would it take to “overload” on protein? – is this a reasonable consideration? Were the vegans consuming excessive amounts of protein powders and other unnatural non whole foods to achieve comparable protein percentages? How much protein do we really need? What is the protein percentages in other cultures that are known for their Health (countries that maintain lower rates of diseases)?
