The American Heart Association (AHA) has issued an advisory concluding that replacing saturated fats with unsaturated fats will lower the incidence of cardiovascular disease (CVD), especially if combined with an “overall healthful dietary pattern." Frank M. Sacks, et al, "Dietary Fats and Cardiovascular Disease: A Presidential Advisory From the American Heart Association," Circulation, June 15, 2017. AHA reviewed multiple studies on the effects of dietary saturated fat intake and its replacement with other types of fats, as well as replacement with carbohydrates, and concluded that replacing saturated fat with polyunsaturated vegetable fat and changing dietary patterns reduces the risk of CVD by as much as 30 percent.

Key recommendations of the review include lowering intake of saturated fat, increasing intake of polyunsaturated fat and avoiding coconut oil, which more than 70 percent of Americans regard as “healthy,” despite that it actually increases LDL cholesterol.
