Mis thats insane. All Dr. who prescribe veg diets arent worth their weight in salt...

The average CUP of cooked lentils has 18 gr of protein. The human body needs .45 grams pf protein per kilogram of body weight, with the maximum being 0.8 grams per kilo. Average weight is lets say... 70 kilos. Your protein requirment is between 30 and 40 grams a day up to about 70 grams a day. 5 oz of tofu have 11 grams, throw in a protein shake, some oatmeal, nuts and you are well over your RDA. Iron is another story all together and meat is not the best source, green leafy vegetable are.
