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—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.

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 foods with saturated fat, like butter or meat, doesn't seem to raise your risk of heart disease or dying from it, based on the studies reviewed.

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 know yet if swapping butter for bread or olive oil makes a difference for heart health — there just isn’t enough solid data from long-term studies to say for sure.
