Tuna fish is a nutrient-rich saltwater fish that has gained immense popularity due to its versatility, affordability, and health benefits. It is a valuable source of protein, omega-3 fatty acids, vitamins, and minerals, making it an excellent choice for maintaining a balanced diet.
Tuna fish is particularly rich in several vitamins and minerals, including:
Omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are essential for heart, brain, and eye health. A 100-gram serving of cooked tuna contains approximately 1.5 grams of omega-3 fatty acids.
Consuming tuna fish regularly provides numerous health benefits:
