Abstract

Alzheimer's disease (AD) is the most common form of dementia, with the risk of developing it attributed to non-modifiable and modifiable factors. Currently, there is no cure for AD. A plant-based diet may protect against cognitive decline, due to the effects of plant-based nutrients such as vitamins, antioxidants, and fiber. The aim of the review is to summarize current literature on plant-based nutrients and their impact on cognition. A search was conducted on PubMed for clinical and murine studies, using combinations of the following words: "Alzheimer's disease", "dementia", "cognition", "plant-based diet", "mild cognitive impairment", "vitamin B", "vitamin C", "vitamin E, "beta carotene", "antioxidants", "fiber", "vitamin K", "Mediterranean diet", "vitamin D", and "mushrooms". A diet rich in vitamin B and antioxidants can benefit the cognitive functions of individuals as shown in randomized clinical trials. Vitamin K is associated with improved cognition, although large randomized controlled trials need to be done. Fiber has been shown to prevent cognitive decline in animal studies. Vitamin D may contribute to cognitive health via anti-inflammatory processes. Several medical organizations have recommended a plant-based diet for optimizing cognitive health and potentially helping to prevent dementia.
