Abstract

A vegan diet may help prevent neurodegenerative diseases like Alzheimer's disease (AD), according to research. The current understanding of the benefits and drawbacks of a vegan diet in relation to the risk of Alzheimer's disease is the primary focus of this review. A vegan diet is low in saturated fats and cholesterol, which helps maintain a healthy lipid profile in the blood and can help prevent Alzheimer's disease. It also has a lot of phytonutrients, like vitamins, antioxidants, and dietary fiber, that might help keep your brain from getting older. Quercetin, a natural inhibitor of monoamine oxidase (MAO) that can help maintain mental health and lower the risk of Alzheimer's disease, is also increased in veganism. However, it is impossible to determine whether vegetarianism or other diets outperform veganism in AD prevention due to a lack of data. A vegan diet may lead to nutritional deficiencies because it lacks certain vitamins and micronutrients. Vitamin B12, vitamin D, and DHA, which have been linked to Alzheimer's disease (AD), are more common in vegans who do not take micronutrient supplements. Therefore, all of the advantages and disadvantages that have been discussed here should be taken into consideration when determining the overall impact of a vegan diet on AD prevention and/or progression.
