Nutritional Value of Fish

Nutritional Value of Fish

Fish is a popular choice for healthy eating, and for good reason. Not only is it delicious, but it also packs a powerful nutritional punch. Fish is a great source of lean protein, omega-3 fatty acids, vitamins, and minerals essential for a healthy diet.

One key nutrient in fish is omega-3 fatty acids. These essential fats are important for brain and heart health and can even help reduce inflammation in the body. Fish is one of the best sources of omega-3 fatty acids, with fatty fish like salmon, mackerel, and sardines being particularly rich in these beneficial fats.
