Hello Amadeus! <<>>This made for me-70kg 500 grams cow-muscle per day >>OR 550g almonds OR 400gs sunflower seed. We can choose or mix. >Nut and plant proteins really are inferior to meat protein in relation to >amino acid profiles. Well, meat also hasn't all that good profile. It's significantely worse than simple egg, for example. Bader than a grain/legume combination. And much bader than potatoes with a little egg added >> What is the standard for comparison? The use of eggs as the "gold standard" for ideal protein is archaic, based on a study that was used by the egg industry as a marketing campaign at the beginning of this century. << Aren't there some studies of connections between protein (or meat) consumption and kindey deseases? Anybody here knows? >> The answer is very simple -- based on volumes of research. Any person with kidney disease or failure is advised to go on a low protein diet. Since Todd has posted on the use of protein as helping kidney disease, perhaps he can put things in perspective -- how many research results in favor of additional protein for kidneys versus less. I suppose it is always possible that some unique pathological condition may exist where additional protein is beneficial, but to draw of a general conclusion from that would be fallacy. Cases of protein deficiency in the US are unknown unlesss the person is anorexic or starving. Amadeus -- wo leben sie? Mahesh
