Which of the following is not considered a source of protein?

The correct answer is that sugar is not considered a source of protein. Protein is essential for various bodily functions, including tissue repair, muscle building, and the production of enzymes and hormones. It is found in foods that are high in amino acids, which are the building blocks of proteins.

Poultry, beans, and dairy are all excellent sources of protein. Poultry, such as chicken and turkey, provides high-quality animal protein, including essential amino acids. Beans are a plant-based source of protein, often rich in fiber and essential nutrients, making them a key component of many vegetarian and vegan diets. Dairy products, like milk, cheese, and yogurt, also contain significant amounts of protein, along with calcium and other vital nutrients.

In contrast, sugar primarily provides carbohydrates and energy but lacks protein content. It contributes to caloric intake but does not offer the amino acids needed for growth and repair, which is why it is not classified as a source of protein.
