THE VITAMIN CONTENT OF FOODSTUFFS

Abstract

The importance of standardized diets in experiments designed to test comparative vitamin content of food is emphasized. By the use of Sherman''s standard diets and methods, the minimum protective dose against scurvy per guinea pig per day of ripe bananas was 5-8 gm.; 0.4-0.5 gm. bananas furnish sufficient vitamin A to produce an average gain of 25 gm. per rat in 8 weeks; more than 7 gm. of bananas are required to furnish vitamin B for a gain of 20 gm. per rat in 8 weeks.
