The biochemist and the anthropologist look at native food problems from very different points of view, but it seems clear that research on African diets will be of scientific value only if there is co-operation between the two. Without chemical analysis it is impossible to know the composition of any particular native diet. Without a knowledge of the customs and language of any tribal area the necessary facts cannot be collected. The present article describes an attempt at co-operation along these lines, based on a study of the diet of a Northern Rhodesian tribe.
page 177 note 1 Infants in this community are weaned at about 2½ or 3 years, but from the third week on they are forcibly fed twice a day with about half a tea-cup of thin millet gruel; while from nine months or so they begin to become accustomed to adult food. Breast-fed infants were omitted in the assessment of the ‘man-values’.
page 177 note 2 A series of consecutive observations in one particular village at different seasons of the year would have been more valuable from the dietetic point of view. Mrs. Gore-Browne hopes to carry out such a study in co-operation with the Bio chemical Department of King's College Hospital, London.
page 180 note 1 All the observations were made in a year of unusual shortage. In an average year some families would have a supply of millet lasting from one year to the next. In Kasaka village, described as typical, six families out of fourteen still had small supplies of last year's grain when the new harvest was reaped.
