If you are a vegetarian, you are probably reaping the health benefits of a great diet. According to Susan Havala Hobbs (author of Being Vegetarian For Dummies), research has proven that vegetarians have lower rates of coronary artery disease, some forms of cancer, diabetes, high blood pressure and obesity . Vegetarians are also less likely to have kidney disease and intestinal problems like diverticulosis.
Some vegetarians (lacto-ovo) don't eat meat but will eat animal products such as egg and dairy products. Vegans, on the other hand, eat no animal products of any kind. Food choices for vegetarians have expanded at grocery stores and restaurants. Vegetarian diets are no longer considered "bland". Like any diet, you must make sure you are getting enough nutrients. Vegans, in particular, should be sure their diets include enough calcium, vitamin B12, iron and protein.
Multivitamins, calcium supplements, etc. can also provide some of these nutrients when diets are lacking.
