Which of the following foods is a good source of protein?

1. Corn oil

2. An orange

3. Fish

4. Grape jelly

The correct answer is: Fish

Fish is an excellent source of protein, making it a valuable part of a balanced diet. Fish provides high-quality protein that contains all the essential amino acids needed for the body’s functioning. It is also rich in omega-3 fatty acids, which can support heart and brain health. In contrast, corn oil is primarily composed of fat and does not provide protein. An orange is a fruit that is nutritious and contains vitamins, particularly vitamin C, but it has very little protein. Similarly, grape jelly is high in sugar and provides minimal nutritional value, including protein. Therefore, fish stands out as the best option when looking for a protein source among the choices provided.
