Been treated for skin cancer and given yeast-derived organic selenium (200 µg selenium per day) or a placebo for several years, selenium had no significant effect on skin cancer reoccurrence, but showed a remarkably large effect on the occurrence of lung cancer (46% reduction), colon-rectum cancer (58% reduction), and prostate cancer (63% reduction).

Proteins are polymers of amino acids that contain the elements carbon, hydrogen, oxygen, nitrogen and sulfur. Particular emphasis is given to the indispensable amino acids, i.e., those that must be in the food supply because they either cannot be synthesized in the body or they cannot be synthesized in adequate quantity to meet the needs for optimal rates of growth in children. The indispensable amino acids are: lysine, methionine, threonine, tryptophan, leucine, isoleucine, valine, phenylalanine, arginine and histidine. A dietary supply of arginine is not required by adults. The amino acids supplied from dietary protein are needed for synthesis of body proteins in muscle, organs, bone and skin, and for synthesis of enzymes, certain hormones, antibodies and a host of specialized products.
