Dr. Wallach's claim that diabetes and hypoglycemia are due to vanadium and chromium
deficiency was said to be unsupported by clinical research. However, published evidence is available that indicates a role of chromium and vanadium on the insulin system and in human diabetes[25-27]. According to USDA's Richard Anderson, ...suboptimal intakes of chromium by people consuming average diets may lead to signs and symptoms of chromium deficiency that include elevated blood glucose, insulin, cholesterol and triglyceride concentration and decreased insulin binding and receptor number.
Extreme signs of Cr deficiency were observed in TPN patients and were corrected by Cr supplementation. Vanadium is being considered as a therapeutic agent for the treatment of diabetes mellitus. Khandelweal and Pugazhenti at University of Saskatchewan, Canada, state: "Several studies have clearly demonstrated that vanadium has the potential to be used as a therapeutic agent for the treatment of diabetes. In a recent study, vanadate was found to enhance insulin sensitivity in diabetic patients." http://www.thewallachfiles.com/wallach.htm
