Sardines are the general name of some herrings, which are widely distributed in temperate marine areas of 6 ~ 20 degrees north and south latitude, and are one of the important economic fish in the world.

Sardines are rich in phospholipids, namely OMEGA-3 fatty acids, protein and calcium. Phospholipids can promote fetal brain development. Omega-3 fatty acids have the function of protecting cardiovascular health. According to the website of the American Cardiovascular Association, this special fatty acid can reduce the production of triglycerides, which has the magical effect of gradually lowering blood pressure and slowing down the speed of atherosclerosis. Sardines also contain a lot of calcium, especially fish bones. The bones of canned sardines are soft and safe to eat.
