Omega-3 fatty acids: Omega-3 fatty acids are essential fatty acids found in some plants and fish. There should be a balance of omega-6 and omega-3 fatty acids for health. There is strong scientific evidence from human trials that omega-3 fatty acids from fish or fish oil supplements significantly reduce blood triglyceride levels. Fish oil supplements also appear to cause small improvements in high-density lipoprotein ("good cholesterol"); however, increases (worsening) in low-density lipoprotein levels (LDL/"bad cholesterol") are also observed. Several well-conducted randomized controlled trials report that in people with a history of heart attack, regular consumption of oily fish or fish oil/omega-3 supplements reduces the risk of non-fatal heart attack, fatal heart attack, sudden death, and all-cause mortality (death due to any cause). Most patients in these studies were also using conventional heart drugs, suggesting that the benefits of fish oils may add to the effects of other therapies. Preliminary studies also report reductions in angina associated with fish oil intake. Better research is necessary before a firm conclusion can be drawn. Caution is advised when taking omega-3 supplements, as numerous adverse effects including an increase in bleeding and drug interactions are possible. Omega-3 supplements should not be used if pregnant or breast-feeding, unless otherwise directed by a doctor.
