Studies of Fat-Free Diets

Abstract

Data are presented comparing the average maximum growth of rats on fat-free diets with that of rats fed methyl linoleate curatively and prophylactically. The minimum level of methyl linoleate for optimal growth effects has been tentatively placed at or below 1 drop (30 mg.) per day per rat. The inability of methyl linolenate to supplement methyl linoleate is proved. The observation has been made that rats fed a highly purified synthetic diet, complete in all known dietary essentials, plateau at subnormal weights. These rats show positive growth response to supplements of brain and liver.
