by Brooke A. Rosenfeld, MS, RD, CDN, Pn1 Whether you have been vegan for years or perhaps you have just started to follow a plant-based diet, this article can be beneficial to you. There is a plethora of research available on the multiple health benefits of following a vegan diet, including increased lifespan, increased immunity, reduced risk of heart disease and other chronic disease, as well as improved athleticism. However, we all must be mindful of the fact that whenever food groups are excluded from our intake, there is an increased risk of nutrient deficiencies.
