Diet and Alzheimer's disease

Alzheimer's disease (AD) is increasing in prevalence, and environmental risk factors have not been identified with certainty. There is evidence that oxidative stress, homocysteine-related vitamins, fats, and alcohol have a role in the pathogenesis of AD. Few large epidemiological studies have explored the associations between nutrients and AD, and there has been only one trial of vitamin E in the prevention of AD. Some studies suggest that high intake of vitamins C, E, B6, and B12, and folate, unsaturated fatty acids, and fish are related to a low risk of AD, but reports are inconsistent. Modest to moderate alcohol intake, particularly wine, may be related to a low risk of AD. Available data do not permit definitive conclusions regarding diet and AD or specific recommendations on diet modification for the prevention of AD. Alzheimer's disease (AD) is increasing in prevalence. There are no known preventive or curative measures. There is evidence that oxidative stress, homo-cysteine-related vitamins, fats, and alcohol have a role in the pathogenesis of AD. Some epidemiologic studies suggest that higher dietary intake of antioxidants, vitamins B(6), B(12), and folate, unsaturated fatty acids, and fish are related to a lower risk of AD, but reports are inconsistent. Modest to moderate alcohol intake, particularly wine, may be related to a lower risk of AD. The Mediterranean diet may also be related to lower AD risk. However, randomized clinical trials of supplements of vitamins E, B(12), B(6), and folate have shown no cognitive benefit, and randomized trials for other nutrients or diets in AD are not available. The existing evidence does not support the recommendation of specific supplements, foods, or diets for the prevention of AD. ...Curr Neurol Neurosci Rep. 2007 Sep;7(5):366-73
