Fish Oil Supplements Might Not Reduce Heart Disease Risk
You may have heard that consuming fish oil reduces heart disease risk. But for people with diabetes who don’t already have heart disease, taking fish oil capsules may not do that. In a study, 15,480 people with diabetes (mostly type 2) were randomly assigned to take daily capsules containing fish oil (also called omega-3 fatty acids) or olive oil and were followed for an average of 7.4 years. None had heart disease at the study’s start. The risk of experiencing a nonfatal heart attack, stroke, or heart-related death was nearly identical between the two groups, as was the risk of death from any cause. The researchers acknowledge that olive oil may have some heart benefits, which would affect how accurately it acted as a placebo. But, they say, the amount of olive oil used in this study was probably too small to have made a difference in heart health. The bottom line: Save your money on the supplements and eat fatty fish, such as salmon and tuna, instead.
