A vegetarian diet is a way of eating that excludes meat, poultry, and fish. People choose this diet for various reasons, including health benefits, ethical concerns about animal welfare, and environmental considerations. Vegetarians typically consume a variety of foods, including fruits, vegetables, grains, legumes, nuts, and seeds. There are different types of vegetarian diets. For example, lacto-vegetarians include dairy products, while ovo-vegetarians include eggs. Some may follow a vegan diet, which eliminates all animal products. A well-planned vegetarian diet can provide all the necessary nutrients for a healthy lifestyle.
