Cow's milk is a nutritious liquid produced by dairy cows, composed of water, protein, fat, lactose, and essential nutrients like calcium and vitamin B12. It is a significant source of protein and calcium, though its saturated fat content can be a consideration, and many individuals have allergies or intolerance to its proteins or lactose. While generally healthy for most, excessive consumption is not recommended, and lower-fat or plant-based alternatives can be chosen for health reasons.
