Meat analogues are canned or frozen meat-like foods derived from vegetable protein, usually soy, gluten, or nuts. They are available in chicken, beef, pork, sausage, and bacon flavors and also as egg substitutes. They vary in many ways so check the package label for information. Just in case you want to have a complete protein dish from plant foods, you can combine complementary incomplete vegetable and grain proteins. But remember, variety throughout the day will supply the complete proteins needed by the body.
Most vegetarian diets tend to be high in bulk and low in fat.
Thus, meeting caloric needs may be difficult, especially for children. Also, with fewer calories, the available protein may be used for energy rather than for the repair of tissues, body cells, and other important functions. You must be careful to eat well-rounded meals to get enough calories and other nutrients. Whether you are a vegetarian or not, you might have difficulty getting the recommended amount of iron. Without meat and eggs, women during the child bearing years may not get enough iron.
