8. Milk
While milk may not be suitable for everyone due to lactose intolerance or dietary restrictions, dairy products like cow’s milk offer an excellent protein source, providing eight grams per serving with relatively low calories.
Cow’s milk is also high in calcium and other minerals that are not easily obtained from other sources. This is because milk is designed to nourish baby cows and support their growth. In humans, consuming milk contributes to healthy bones and teeth.
