I am a vegetarian and have been for 14 years. As with most diets, it can be very healthy if done right. It is important to be sure your diet is balanced and that you are getting all the essential nutrients you need. Also, take suppliments for what you lack. For the vegan diet, vitamin B-12 and calcium are hard to come by.

actually chickpeas are a better source of calcium than milk ... haha and dark green vegis are great for that as well...b-12 is hard though
