By Lance Johnson(NaturalNews) A new study conducted by Dr. Michael Orlich of Loma Linda University in California is shedding more positive light on the benefits of switching to a vegetarian diet.A truly vegetarian diet is one that avoids all products that come from animals, even eggs and milk. A vegetarian diet consists primarily of grains, nuts, beans, herbs, legumes, berries, vegetables, and fruits. According to a 2012 Gallup poll, only 5 percent of American's eat this way. Others eat similar diets. Lacto-vegetarians eat dairy and eggs but not fish and meat. Pesco-vegetarians do eat fish.
