It's Not Healthy

Plant-based diets are restrictive, just like any diet that cuts out certain items. And there's a concern that you won’t get all the vitamins and minerals you need without consuming animal products. (“Where do you get your iron? B12? Calcium?”) But a vegan diet can improve your health. According to a study by the American Journal of Clinical Nutrition, it has may even help reduce cancer risk. In some cases, it may be good to add supplements to your diet (but be sure to talk to a doctor first). Dark, leafy greens provide iron, as well as the vitamin C to help absorb it, not to mention a host of other vitamins, including A, E, K, B6, and the mineral calcium.
