Is Vegetarian Healthy?

The answer? Yes! You can have all your body's needed nutrition, plus save money by eating vegetarian once or twice a week.
According to the US Department of Agriculture "Vegetarian diets can meet all the recommendations for nutrients." (view website)
There is no worry about getting enough protein. Some vegetable sources like tofu (soy), buckwheat and quinoa have complete protein without the unhealthy fats of meat. Other foods need to be eaten in combination--like rice and beans (think Mexican food), lentils and rice (Indian food). Read more about combinations here.
The US Department of Agriculture goes on to say:
"The key is to consume a variety of foods and the right amount of foods to meet your calorie needs. Follow the food group recommendations for your age, sex, and activity level to get the right amount of food and the variety of foods needed for nutrient adequacy. Nutrients that vegetarians may need to focus on include protein, iron, calcium, zinc, and vitamin B12.

Nutrients to focus on for vegetarians
Protein has many important functions in the body and is essential for growth and maintenance. Protein needs can easily be met by eating a variety of plant-based foods. Combining different protein sources in the same meal is not necessary. Sources of protein for vegetarians include beans, nuts, nut butters, peas, and soy products (tofu, tempeh, veggie burgers). Milk products and eggs are also good protein sources for lacto-ovo vegetarians.
Iron functions primarily as a carrier of oxygen in the blood. Iron sources for vegetarians include iron-fortified breakfast cereals, spinach, kidney beans, black-eyed peas, lentils, turnip greens, molasses, whole wheat breads, peas, and some dried fruits (dried apricots, prunes, raisins).
Calcium is used for building bones and teeth and in maintaining bone strength. Sources of calcium for vegetarians include fortified breakfast cereals, soy products (tofu, soy-based beverages), calcium-fortified orange juice, and some dark green leafy vegetables (collard greens, turnip greens, bok choy, mustard greens). Milk products are excellent calcium sources for lacto vegetarians.
Zinc is necessary for many biochemical reactions and also helps the immune system function properly. Sources of zinc for vegetarians include many types of beans (white beans, kidney beans, and chickpeas), zinc-fortified breakfast cereals, wheat germ, and pumpkin seeds. Milk products are a zinc source for lacto vegetarians.
Vitamin B12 is found in animal products and some fortified foods. Sources of vitamin B12 for vegetarians include milk products, eggs, and foods that have been fortified with vitamin B12. These include breakfast cereals, soy-based beverages, veggie burgers, and nutritional yeast.
Tips for Vegetarians
Build meals around protein sources that are naturally low in fat, such as beans, lentils, and rice. Don’t overload meals with high-fat cheeses to replace the meat.
Calcium-fortified soy-based beverages can provide calcium in amounts similar to milk. They are usually low in fat and do not contain cholesterol.
Many foods that typically contain meat or poultry can be made vegetarian. This can increase vegetable intake and cut saturated fat and cholesterol intake. Consider:
pasta primavera or pasta with marinara or pesto sauce
veggie pizza
vegetable lasagna
tofu-vegetable stir fry
vegetable lo mein
vegetable kabobs
bean burritos or tacos
A variety of vegetarian products look (and may taste) like their non-vegetarian counterparts, but are usually lower in saturated fat and contain no cholesterol.
For breakfast, try soy-based sausage patties or links.
Rather than hamburgers, try veggie burgers. A variety of kinds are available, made with soy beans, vegetables, and/or rice.
Add vegetarian meat substitutes to soups and stews to boost protein without adding saturated fat or cholesterol. These include tempeh (cultured soybeans with a chewy texture), tofu, or wheat gluten (seitan).
For barbecues, try veggie or garden burgers, soy hot dogs, marinated tofu or tempeh, and veggie kabobs.
Make bean burgers, lentil burgers, or pita halves with falafel (spicy ground chick pea patties).
Some restaurants offer soy options (texturized vegetable protein) as a substitute for meat, and soy cheese as a substitute for regular cheese."
