Cutting back on foods like butter and fatty meats doesn’t seem to make people live longer or die less from heart disease or cancer, according to studies that aren’t super strong.

Eating less saturated fat doesn't seem to reliably help people live longer or avoid heart disease deaths, whether they're healthy or already have heart disease.

We don’t have strong enough proof to say whether eating less saturated fat makes heart attacks, strokes, or heart disease deaths more or less likely — the studies we have aren’t very reliable.

Eating less saturated fat can slightly lower your bad cholesterol, but that doesn’t mean you’ll live longer or have fewer heart problems unless you’re changing other parts of your diet too.

Eating less saturated fat—like butter or fatty meats—doesn’t seem to lower the risk of dying from heart problems or other causes, even after years of doing it, according to a review of nine big studies.

Eating more saturated fat from meat, butter, or cheese doesn’t clearly make people more likely to die early or get heart disease or diabetes, but the science isn’t strong enough to be sure.
