But th& people who can afford such a diet do not eat much bread anyhow. It is among the poorer classes, and especially the children of the poorer classes, where bread represents the bulk of the daily diet, and where butter is replaced by margarine, that the absence of vitamin B from white bread has to be considered as a serious dietetic defect. Reports of medical officers of health show that many of these children live on a diet composed of white bread, margarine, jam, and fish, with perhaps some potatoes. Such a diet is certainly deficient in both vitamin A and B, and could be madeadequate as regards the latter vitamin by the consumption of bread rich in vitamin B." On
