The highly nutritious tuna fish, found mostly in warm water areas, is considered a delicacy in almost all parts of the world, mainly because of its intense flavor and meaty texture. Canned or fresh (as steaks, pieces or fillets), the species is regarded as a culinary treat and is particularly popular in the coastal areas of the world. However, the fresh varieties have higher content of the beneficial Omega-3-fatty acids, as compared to the canned ones and hence are preferred. Tuna belongs to the order Perciformes and the family Scombridae. There are over 48 different species of the fish found worldwide, which includes the popular blue-fin, Albacore, Slender tuna and the Frigate tuna. The fish is available commercially all around the year. However, the best season for the purchase and consumption of the fresh Hawaiian variety is the month of December.

They are especially beneficial for the maintenance of a healthy cardio-vascular system. They also prevent erratic heart rhythms, leading to less possibilities of blood clotting inside arteries and maintain a higher level of HDL as compared to the LDL levels (harmful cholesterol).
- The vitamin B6 present in the fish is essential for the process of methylation. The vitamin, along with folic acid, lowers the levels of homocysteine in the body. This compound is produced during the methylation cycle and is considered as a major risk factor for atherosclerosis, as it damages the artery walls.
- Recent studies have indicated that consumption of tuna can help in lowering the rate of stroke in humans, particularly the ischemic form of stroke.

Emboli are formed when a part or all of the blood clots in the deep veins dislodge from the site, where it is formed and moves through the venous system to different parts of the body.
