What is a "vegetarian" diet, you may ask. While my research reveals there seems to be no single specific "vegetarian" eating pattern, there are several prevalent types of vegetarian eating patterns. Both the American Heart Association and The Mayo Clinic list the following as types of vegetarian diets:
vegan or total vegetarian in which the only foods consumed are from plants, vegetables, legumes (dried beans and peas), fruits, seeds, nuts and grains;
lacto vegetarian which includes the plant foods listed above plus cheese and dairy products;
