A lacto-vegetarian is someone who follows a vegetarian diet that includes dairy products but excludes meat, fish, and eggs. This diet allows for the consumption of milk, cheese, yogurt, and other dairy items, providing essential nutrients like calcium and protein. Lacto-vegetarianism is often chosen for health, ethical, or environmental reasons. By avoiding meat and fish, individuals may reduce their risk of certain diseases and contribute to animal welfare. This dietary choice can also have a lower environmental impact compared to diets that include meat.
