Protein cannot be overemphasized
Antibodies, white blood cells, the complement, and lymph cells are all made of complete protein. A lack of this nutrient can prevent recovery from infections regardless of the amounts of vitamins obtained. When a low-protein diet has been replaced by one high in protein, the production of antibodies has increased within a few hours. Of single amino acids, methionine and tryptophane, generously supplied in eggs and milk, are particularly valuable. Of single proteins tested for their ability to build body defenses, liver, yeast, and especially wheat germ proved most valuable. Egg yolk, milk, meat, and soy flour, in this order, particularly increased the production of white blood cells.
