DESCRIPTION: Nutritional quality indices show plant-based diets are the healthiest, but do vegetarians and vegans reach the recommended daily intake of protein? The only nutrient Americans may be more deficient in than fiber is potassium. See 98% of American Diets Potassium Deficient (http://nutritionfacts.org/video/98-of-american-diets-potassium-deficient/). For more on how S.A.D. the Standard American Diet is, see Nation's Diet in Crisis (http://nutritionfacts.org/video/nations-diet-in-crisis/). Americans eating meat-free diets average higher intakes of nearly every nutrient.
