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 a source of protein and calcium. Lacto-vegetarians often choose this lifestyle for health, ethical, or environmental reasons. By avoiding animal flesh while still consuming dairy, they can enjoy a variety of foods while adhering to their dietary preferences. This diet can be rich in fruits, vegetables, grains, and legumes, promoting overall health and well-being.
