A
vegan diet is safe once you understand the basic parameters of the essential components and then apply them regularly. This is actually quite easy once you really get into it. I have been vegan for 6 years now and it is extremely enjoyable. My health has increased dramatically due to this change.
Dr. Gabriel Cousens has done extensive research on thousands of successful vegans at the Tree of Life Rejuventation Center.
Websites like vegansociety(dot)com give great information on the holistic nature of veganism and detailed advice on how to get started.
Vegan vitamin and mineral powders such as Vitamineral Green from Health Force Nutritionals are a nice thing to take occasionally, and when you are starting a
vegan diet. That being said, a balanced and varied
vegan diet is

Yeah, red lobster would not be my first choice for

Even though you may not always want one, vegan salads are actually pretty easy to come by at a restaurant. This is often what I do when I am out with friends.

Vegans eat a wide variety of plant based foods such as nuts, seeds, vegetables, greens, fruits, seaweeds, herbs, legumes, grains, and sprouts. These can be cooked or raw. I personally eat a mixture of raw and cooked foods. By the way, there are some good vegan mock tuna recipes out there.
