[Alzheimer's disease. Current evidence on the preventive role of nutrition].

Introduction

in the last decades, a significant increase in the incidence of Alzheimer's disease (AD) has been observed. Currently, there are no effective pharmacological treatments available, which makes preventive measures particularly important.

Objective

to analyze the available scientific evidence on nutritional and dietary factors and their association with AD prevention.

Methods

a review of nutritional and dietary factors related to the prevention of AD was conducted.

Results

several dietary components have been positively associated with AD prevention, including intake of complex carbohydrates, fiber, omega-3, plant-based proteins, vitamins (folates, choline, vitamin D, C, B6 and B9), zinc, some bioactive compounds such as flavonols and probiotics. Following the Mediterranean, Dietary Approaches to Stop Hypertension (DASH) y Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diets has been associated with a lower risk of developing the disease.

Conclusion

nutrition may have a protective role against AD, although further studies are needed in this regard.
