Changes in Vitamin A and C Levels In Black Mine-Workers
Abstract
An investigation of the vitamin A and C status of Black mine-workers was carried out at the request of the Anglo American Corporation of South Africa Ltd. It was found that, although there was no evidence of widespread vitamin A deficiency, there was sufficient evidence of subclinical deficiency to warrant further investigation. In spite of apparently adequate vitamin C intakes, a relatively high incidence of subclinical vitamin C deficiency was found. It is strongly recommended that further studies be undertaken to establish what are the minimum levels of vitamin A and C required daily to reduce effectively the incidence of subclinical deficiency.
