These benefits are likely due to the fact that vegan diets are abundant in antioxidants and phytochemicals, which help protect the brain from damage. In addition, vegan diets are typically low in saturated fats and high in healthy fats, like omega-3s, which are essential for cognitive health.
A vegan diet has also been shown to improve mental health by reducing inflammation. Inflammation has been linked with many mental health conditions, including anxiety and depression. Therefore, by reducing inflammation, a vegan diet can help improve mental health.
