In the course of an anthropometric and clinical survey of schoolgirls in a rural Bantu Reserve, development of secondary sexual characteristics was noted.

One hundred and twenty Wistar rats were divided into 3 groups.

The processing procedure required to render soy-beans nutritionally acceptable is discussed and the techniques employed to prepare soy-bean meal as an ingredient of the NNRI food mixture are given.

Existing and former schemes designed to improve the nutrition status of the population of various countries are examined to determine the causes of their success or failure.

Serum-protein levels were determined on sera from 301 Pedi schoolchildren living in a rural Bantu Reserve.

In an experiment with 5 groups of young rats, each group receiving a basal diet of cooked and dried maize meal plus NNRI Food Formula V and certain supplements for 140 days, it was found that: the basal diet plus coconut oil induced hyaline degeneration in myocardium and skeletal muscle; the incidence rating of the hyaline degeneration was raised to 100% and the degree of tissue change was enhanced by supplementation of the basal diet with cod-liver oil; supplementation of the basal diet with vitamin E afforded complete protection against hyalinization; and supplementation with selenium and anti-oxidants afforded only a limited degree of protection against the muscular tissue changes.

The food intake and activity patterns were recorded for 11 male Indian students over a 7-day period. Energy expenditure was estimated for the recorded activities and also calculated from tables.
