Canned sardines in low-salt olive oil combine the best that can be consumed to benefit cardiovascular health. Sardines, being an oily fish, are recommended for their high content of Omega 3, a polyunsaturated fatty acid, which protects the heart and helps reduce the risk of heart attack, controlling cholesterol levels in the blood. Olive oil is, in turn, the preferred source of fat in the Mediterranean diet. The low salt content helps control blood pressure levels.
