Effect of a Vegan Mediterranean Diet on Cardiometabolic Biomarkers, Functional Capacity, and Quality of Life in Patients with Fibromyalgia

The vegan mediterranean diet is mainly composed of whole plant-based foods, similar a una dieta mediterránea, but the animal sources of protein and fat are substituted with plant foods rich in protein and fat. During the vegan diet, participants are supplemented with 1000 µg of cyanocobalamin (vitamin B12) twice a week (Harrison Sports Nutrition, Granada, Spain) to compensate for the deficiency in vitamin B12 intake induced by the vegan diet.
