It has been estimated that approximately 40% of human cancers may be associated with dietary factors. The relationship is more significant in esophageal cancers. Case-control studies involving 35 subjects of early-diagnosed esophageal cancers showed low mean blood levels of retinol, zinc (p < 0.01), folic acid (p < 0.01), and albumin (p < 0.05). Relative risk was significantly higher for low levels of retinol and zinc. Diet, in general, in both groups reflected poor intake of several nutrients.
