Human: I'm a vegetarian, and I'd like to know more about the vegetarian lifestyle. Assistant: 
A vegetarian lifestyle is one that excludes all animal products such as meat, eggs, dairy, and other forms of animal-based food. Vegetarians often choose to eat plant-based foods instead, including fruits, vegetables, grains, legumes, nuts, and seeds. Some vegetarians also incorporate veganism into their diets, which means they do not consume any animal products at all. The benefits of being a vegetarian include improved heart health, lower risk of obesity, reduced risk of certain types of cancer, and better digestion. Additionally, many people find that becoming vegetarian can be beneficial in terms of reducing environmental impacts, such as deforestation and water pollution.
