Vitamin E, vitamin C, and beta-carotene lower Alzheimer's risk
Certain vitamins and minerals may improve brain health and prevent disease. In this meta-analysis, researchers reviewed seven studies looking at the link between the amount of antioxidants consumed through diet and the development of Alzheimer's disease.
After review of these studies, researchers observed that people who ate higher amounts of vitamin E, vitamin C, and beta-carotene had a lower risk of developing Alzheimer's disease compared with people who ate the least amount of these antioxidants.
The study authors comment, "Oxidative damage caused by various types of free radicals [which cause damage to cells and organs] has been widely accepted to play a vital important role in the pathogenesis of Alzheimer's disease and other age-associated neurodegenerative diseases." They add that the results of their meta-analysis suggest that dietary vitamin E, vitamin C, and beta-carotene may help lower the risk of Alzheimer's disease, and comment that "among the three antioxidants, vitamin E exhibits [the] most significant protective effect." As the research was observational, these results do not prove a cause-and-effect relationship. Further research is needed to confirm these findings.
