Some years ago Osborne and Mendel1 reviewed the work which had been done on low fat diets, and from an experiment with 6 young male rats concluded that “if true fats are essential for nutrition during growth, the minimum necessary must be exceedingly small.” In view of the fact that their experimental animals were compared with the animals reared on a diet high in fat but low in protein, it seemed probable that both the controls and the experimental groups were subnormal, thus leaving the question unsettled.†It has been observed in this laboratory that our lard free diet 316 (Table I) is uniformly inferior to the high fat diet 232. Recently a carefully controlled experiment has been conducted to compare diet 316 plus 2 drops of cod liver oil (Patch) daily with diet 232. The groups of 15 females were made up of littermate sisters. Each diet was supplemented by 0.7 gm. yeast (Fleischman) daily. Table II gives the average results. It will be seen that the performance on the 2 diets is very different, the ani...
