Lacto vegetarianism means eating food that does not have meat like chicken, beef or fish, but still includes dairy products like milk, cheese, and yogurt. It is a type of vegetarianism that allows people to get their protein from plant sources like beans, legumes, tofu, and nuts, and still have a balanced diet that includes milk products. By avoiding meat, lacto vegetarians can lower their risk of heart disease, obesity, and other health problems that can come from consuming too much animal fat. It is important for lacto vegetarians to make sure they get enough protein and nutrients from their plant-based foods, so they stay healthy.
