Fish are a good source of protein and _______.

Fish are indeed a good source of protein and fat, particularly healthy fats known as omega-3 fatty acids. These essential fatty acids are beneficial for heart health, brain function, and overall well-being. Including fish in your diet can help provide the necessary nutrients that support various bodily functions.

Healthy fats found in fish contribute to a balanced diet, making them an excellent choice not only for their protein content but also for their fat profile. While the other options may also contain important nutrients, they do not encompass the specific benefits associated with fish as a source of dietary fat. For example, carbohydrates and fiber are primarily found in plant-based foods, whereas vitamins and minerals are present in many food groups, not specifically emphasizing the relationship with fish.
