Esophageal cancer: Vitamin and lipotrope deficiencies in an at‐risk South African population

Abstract
The nutritional status of individuals from areas of South Africa that are known for having a high incidence of esophageal cancer was investigated. Our results show that individuals living in high‐risk areas differ significantly from those in low‐risk areas with respect to vitamins A, E, and B12 in addition to folate. These results suggest that deficiencies in these nutrients may play a significant role in the etiology of esophageal cancer.
