There are lots of great reasons to consider adopting a vegan or vegetarian diet, not the least of which is that for the most part this type of diet consists of food sources that are more sustainable than a typical burger-and-pizza diet is.

Over at the Mayo Clinic web site they have a fantastic primer on vegetarian diet and nutrition.  There's no lectures or pictures of abused chickens, just excellent well-written information on how to adopt aspects of vegetarianism into your diet while maintaining a healthy nutritional balance.

Whether you're a hardcore lifelong vegan or just someone considering cutting back on your intake of red meat you owe it to yourself to hit the jump and learn more.
