Fish is an excellent source of food for various reasons.
Fish is filled with vitamins such as D and riboflavin. Fish is rich in calcium, phosphorus, iron, zinc, iodine, magnesium, and potassium.
Hence, fish is considered to be highly nutritious. The omega-3 fatty acids found abundantly in marine fishes (polyunsaturated fatty acids) reduces cholesterol levels and the incidence of stroke and heart diseases. The omega-3 fatty acids also enhance cognitive development.
Hence, it is highly recommended to have fish at least twice a week.
