Vegan Diet

Vegan diets exclude all animal products. Veganism has rapidly increased in popularity, although randomized trials are still few in number. Trials do show promise for a variety of outcomes, from weight loss to autoimmunity, although comparisons to other popular diets are rare. A vegan diet should be balanced and low in processed food (e.g. a "Whole Food Plant-Based diet") for optimal results.

Our evidence-based analysis on vegan diet features 12 unique references to scientific papers.
