Cereals and rickets

Abstract
Treatment of maize with HC1 improved its antirachitic properties in proportion to the extent that its phytin was hydrolysed. The inorganic P content of variously treated samples of maize bore a direct relation to the antirachitic effectiveness of the ration and an inverse relation to the phytin content. Phytin was a poorly available source of P in contrast with phosphoric acid and Na glycerophosphate. Acid-treated maize produced slightly better calcification than untreated maize, beyond that which could be accounted for by the increase in inorganic P content. The possible existence of other factors must still be given consideration.
