Protein requirements overrated. There is one other argument that the meat-eaters put forth that I feel should be answered here. This just isn't true. In the first place the body only needs 20 to 30 grams a day, not 50 or 100. Secondly, too much protein and undigested proteins are a major cause of toxemia in the body.
Body can convert.
This too, is unfounded. In the first place, we are not recommending a vegetarian diet but a frugitarian diet which besides fruits and vegetables, includes nuts and seeds, many of the latter having a goodly supply of proteins. Furthermore, the body is capable of manufacturing the essential proteins it needs though they may not be in the diet itself. An example of this process is the cow, which eats nothing but grass, yet is the best example of producing hundreds of pounds of protein on the hoof. Whereas the human body is not as efficient in converting vegetable matter into protein as is a beef, nevertheless it, too, has this ability, and the process is the same.
