Was reading about amino acid nutrition and saw that arginine can cause lysine antagonism if the lysine level is more than 1:1.2. Exceeding this ratio can reduce duckling growth. Most foods do not even come close....except brewers yeast which is 1.8:2.4 % of the protein. Makes me think that it shouldn't be suggested that brewers yeast be sprinkled on top of the food (they will probably eat a dis-proportional amount of brewers yeast that may affect the AA balance), but rather suggest mixing it with the food to avoid any possibility of detrimental effects.
