Which of the following is a cardioprotective fatty acid a) Palmitic acidb) Stearic acidc) Oleic acidd) Omega-3 fatty acids

Omega-3 fatty acids > 'c' i.e., Oleic acid  Saturated fatty acids (palmitic acid and stearic acid) increase the risk of CHD. Monounsaturated fatty acids (oleic acid) and co-3 fatty acids, both reduce the risk of CHD. However, co-3 polyunsaturated fatty acids are most cardioprotective:- "Dietary co-3 polyunsaturated fats suppress cardiac arrhythmias, reduce serum triacylglycerols, decrease the tendency for thrombosis, lower BP, and substantially reduce the risk of cardiovascular mortality".
