Which type of foods are included in the protein category?

The protein category primarily includes foods that are rich in protein, which is an essential macronutrient necessary for building and repairing tissues, as well as producing enzymes and hormones. Meats and eggs are excellent sources of complete proteins, meaning they contain all the essential amino acids that the body cannot produce on its own. These foods also provide important nutrients such as iron, zinc, and B vitamins, which are vital for overall health.

In contrast, the other categories mentioned do not typically provide significant amounts of protein. Fruits and vegetables generally contain low levels of protein, while cereals and grains might provide some protein, they are usually not as rich or complete as meats and eggs. Desserts and sweets are primarily composed of sugars and fats, offering little to no protein. Therefore, the inclusion of meats and eggs in the protein category is correct due to their high protein content and nutritional benefits.
