Tuna and health

Tuna is a healthy and nutritious food, high in protein and low in fat and calories. Among the essential nutrients it contains are: calcium, niacin, vitamins A, B and D, and Omega 3 acids.

Tuna proteins, like those of other fish, are easily digested and metabolized with high efficiency. A 6 ounce can of tuna can provide a third of the recommended daily portion of protein and 40% of the recommended daily allowance of vitamin B12.

Canned tuna (canned or glass) maintains its nutritional value when properly processed. A 100-gram serving of tuna in water has about 116 calories.

Nutritional intake

Tuna contains large amounts of omega-3 fatty acids, good for the heart and for good neural and joint performance. These acids also help prevent thrombosis and arteriosclerosis, improve the brain functions of people in adulthood and reduce the risk of mental illness in old age.

It also helps lower blood pressure and can regulate and lower blood cholesterol levels.
