Interestingly, some scientists believe that eating saturated fat may actually have some benefits, including improving the blood lipid profile. ![]() While it’s true that saturated fat promotes higher levels of LDL cholesterol, the story is a bit more complex ( 21). Proponents of this popular opinion often point to studies showing that saturated fat increases levels of “bad” LDL cholesterol. In fact, health authorities have advised people to limit their saturated fat intake for decades. Others are still convinced that excessive saturated fat intake is a risk factor for heart disease ( 20). Observational studies investigating the association between saturated fat and heart disease have provided mixed results ( 1, 15, 16, 17, 18).Ī recent review of studies concluded that eating less saturated fat is linked to a 17% reduced risk of heart disease when it’s replaced with polyunsaturated fat ( 19).Ĭonversely, switching saturated fat out for carbs or protein appears to have no effects ( 19).Īs a result, some experts doubt that saturated fat intake is really a cause for concern.
