In general, plant proteins are healthier than animal proteins due to their content of antioxidants, phytonutrients and fiber responsible for reduced blood cholesterol level and lowered risk of heart disease, high blood pressure, cancer, obesity, and diabetes. Plant-based foods are an incomplete source of protein because they are deficient in some essential amino acids (i.e., tryptophan, lycine, methionine, and isoleucine). Despite this, vegans can still get adequate amounts of amino acids by consuming a good mix of nuts, seeds, beans, grains, and soy. Animal foods are a good source of vitamin B12, heme iron, zinc, and vitamin D. Plant-based foods are absent in vitamin B12, contain non-heme iron which is not readily absorbed, and are deficient in zinc and vitamin D.
BOTTOM LINE: Plant-based protein foods are generally healthier because their consumption may reduce the risk of heart disease. But animal protein foods contain all of the essential amino acids and important micronutrients (e.g., vitamin B12, zinc, etc.) lacking in plant-based foods. Thus, the best advice is to eat a good mix of plant-based and animal proteins to get nutritional benefits from both food sources of protein.
