Wow; a new step in pseudoscience right there. Next they will be telling me that vegan-ism is super healthy. Check out the 4th source. That study specifically destroys the implication/agenda this article is trying to push.
To Quote:
"The purpose of this review is to evaluate the scientific validity of AHA Nutrition Committee's statement on dietary protein and weight reduction (St. Jeor ST et al. Circulation 2001;104:1869–1874), which states: "Individuals who follow these [high-protein] diets are risk for ... potential cardiac, renal, bone, and liver abnormalities overall. Simply stated, there is no scientific evidence whatsoever that high-protein intake has adverse effects on liver function. Relative to renal function, there are no data in the scientific literature demonstrating that healthy kidneys are damaged by the increased demands of protein consumed in quantities 2–3 times above the Recommended Dietary Allowance (RDA)."
There is absolutely no friggin way a high protein intake does anything but good to your system if your kidneys aren't shot. It's an absolutely fallacious claim. Period.
