People who eat a well-planned, well-balanced vegetarian diet are often at less health risk for diabetes, heart disease, obesity, hypertension and some forms of cancer. Vegetarianism is considered a healthy diet due to being mainly comprised of foods high in fiber and low in saturated fat.
Vegetarians must pay careful attention to their meal plan, choose a wide variety of healthy foods and meet caloric requirements to ensure healthy eating. A person on a vegetarian diet should choose whole grain foods, non- or low-fat dairy products and limited sweets. If a vegetarian diet includes too many fried foods, eggs and whole milk products, overall fat intake can be too high. Some vegetarians, particularly vegans, may be at risk for certain vitamin deficiencies, such as vitamins D and B12, riboflavin, calcium and zinc.
