The American Heart Association is changing recommendations for the optimal blood triglyceride levels.
In new guidelines released Monday the AHA suggest lowering them by 33 percent from previous levels. The recommendations suggest people do this with major lifestyle changes including physical activity, weight loss, and dietary changes.
Unlike lowering cholesterol, lifestyle changes are thought to be enough to reduce these blood fats to appropriate levels, so no medications are recommended.
About one-third of adults in the U.S. have elevated triglyceride levels, which is defined as more than 150 milligrams per deciliter.
