Investigations on the consumption of sugar by South African populations
By means of questionnaires, appropriate for both individuals and households, surveys of sugar intake have been carried out in the Transvaal on groups of South African Whites, Indians, Malays, Coloureds, and Bantu. Inquiries concerned groups in urban and rural areas, and in different socio-economic circumstances. In Whites the consumptions per capita resemble data published in the United Kingdom. Mean intakes, in round figures, range from 80 to 100 g per day for those in the higher socio-economic groups, to 120 - 140 g for those in lower-income groups. For Indians the mean consumptions, 70 - 90 g, are less than the intakes of Whites, and slightly less than the limited data on Coloureds and Malays. The Coloureds and Malays were not extensively investigated; the mean intakes of about 90 g are lower than those of Whites in similar economic circumstances. Among the rural groups of Bantu studied, mean intakes range from 65 to 75 g per day, while in urban areas ranges are greater, 55 - 85 g per day. Miscellaneous findings were that males consume more sugar than females; intake rises with age, but falls off in late middle-age; intake falls with increase in family size; and among Whites, intake tends to decrease with rise in privilege (this change is not yet apparent in non-White groups). In the future, sugar intake will certainly increase in the non-White populations, particularly the Bantu.
