A recent trend in dieting is to go vegetarian. A vegetarian diet can allow people to live a healthier and more energetic life. Not only are vegetarian diets more healthy, but they are also cheaper and can also have a positive impact on the environment. There are a wide variety of different vegetarian and semi-vegetarian diets. They range from fully vegetarian to diets that allow eating all kinds of meat other than red meat. Anyone partaking of a vegetarian diet of any kind needs to take care to ensure they are getting all necessary nutrients.
