Tuna Benefits
An excellent source of high quality protein, tuna is rich in a variety of important nutrients including minerals such as selenium, magnesium, and potassium; the B vitamins niacin, B1 and B6; and perhaps most important, the beneficial omega-3 essential fatty acids. These essential fatty acids are vital for human health but cannot be produced by the human body; they must therefore be obtained from foods. Cold-water fish like tuna is a rich source of the omega-3 essential fats, a form of necessary fatty acids in which the standard American diet is sorely deficient.
Cardiovascular Health
Omega-3 fatty acids provide a broad array of cardiovascular benefits. Omega-3s benefit the cardiovascular system by helping to prevent erratic heart rhythms, making blood less likely to clot inside arteries (which is the ultimate cause of most heart attacks), and improving the ratio of good (HDL) cholesterol to potentially harmful (LDL) cholesterol. And, as mentioned above, omega-3s reduce inflammation, which is a key component in the processes that turn cholesterol into artery-clogging plaques.
