title: Nutrient intakes among rural Transkeians at risk for oesophageal cancer.
abstract: The frequency of low nutrient intakes was investigated in areas of moderate and high oesophageal cancer incidence in Transkei by means of 24-hour recall and habitual intake studies in children and nursing mothers. The results in moderate- and high-risk regions were similar and habitual intakes of protein, energy, phosphorus, iron, thiamine and vitamin A were generally satisfactory. Intakes of less than two-thirds the Recommended Dietary Allowances (RDA) had a high frequency of inadequate intakes for calcium (90%), nicotinic acid (79%), riboflavin (55%) and ascorbic acid (50%). It is concluded that the possibility of long-standing deficiencies of the latter three vitamins playing a role in oesophageal carcinogenesis should be considered.
