“Some people still worry about whether a vegetarian diet can provide all essential nutrients. However, it is very easy to have a well-balanced diet with vegetarian foods, since these foods provide plenty of protein. Careful combining of foods is not necessary. Any normal variety of plant foods provides more than enough protein for the body’s needs. Although there is somewhat less protein in a vegetarian diet than a meat-eater’s diet, this is actually an advantage. Excess protein has been linked to kidney stones, osteoporosis, and possibly heart disease and some cancers. A diet focused on beans, whole grains, and vegetables contains adequate amounts of protein without the “overdose” most meat-eaters get.

Calcium is easy to find in a vegetarian diet. Many dark green leafy vegetables and beans are loaded with calcium, and some orange juices, non-dairy “milks,” and cereals are calcium-fortified. Iron is plentiful in whole grains, beans, and fruits.”(PCRM.ORG)
