“Funny, they never mention that the protein in a good protein powder is higher-quality and CHEAPER than the protein you get at the grocery store by buying milk, eggs, poultry, beef, etc.”
Absolutely. These kinds of articles are pure garbage. Also, the notion that 1/2 gram of protein per pound of body weight is sufficient is also nonsense. This nugget of misinformation has been floating around for a long time, and stems from paranoia about the effects of too much protein. Anything over 2 grams/pound is probably overdoing it, and may be risky, but most serious lifters are going to be in the 1 to 2 g/lb range, with no ill effects.
The anti-protein hysteria is overflow from the anti-steroid hysteria, which is, I am convinced, a kind of emanation from the penumbras of male-hatred. I.e., feminazism.
