Diuretic effect: a substance that causes release of excess urine. High protein diet can strip bones of calcium and make them weaker. 9 essential amino acids not synthesized in the body. Complete protein: contains all the essential amino acids. Biological value: amount of nitrogen removed divided by the amount of nitrogen consumed. Legumes, soy, grains, vegetables, nuts, and seeds. Rarely find a person who is protein deficient alone ,if so usually energy depleted as well. Marasmus: muscle loss, increased infection, decreased work capacity.
