Which food group is considered high in protein?

Dairy products are considered high in protein primarily due to their nutritional composition. They typically contain significant amounts of casein and whey, which are high-quality proteins that provide all the essential amino acids the body needs. Foods in the dairy group, such as milk, cheese, and yogurt, not only offer protein but also other essential nutrients such as calcium, vitamin D, and phosphorus, which are important for bone health and metabolic functions.

In contrast, fruits generally have very low protein content and are more known for their vitamins, fiber, and sugars. While grains can provide some protein, particularly whole grains, their protein content is lower compared to dairy products, and they may not have all essential amino acids. Vegetables also contribute protein to the diet, but they typically contain less protein than dairy and often lack some essential amino acids. Therefore, dairy products stand out as a key source of high-quality protein in nutritional guidelines.
