Eating more red meat — which has certain types of fat — might raise your chance of getting heart disease by 7% for every extra 1% of your daily calories that come from those fats.

Eating processed meats like bacon or sausages every day is linked to a higher chance of heart disease, but eating regular red meat like steak or burgers doesn’t seem to raise the risk—so it might be the processing, not the meat, that’s the problem.

Not all saturated fats are the same—those in cheese and butter might not hurt your heart, and could even help, but the ones in bacon and sausages might make your heart risk higher.

Eating fish that contains saturated fat might actually help protect your heart — for every little bit more saturated fat you get from fish, your risk of heart disease goes down by 13%.

For people who already have heart disease, eating foods high in saturated fats—like butter or red meat—doesn’t seem to make their chances of having a heart attack or dying any higher or lower.

Eating more saturated fat—like in butter or red meat—doesn’t seem to make people more likely to get heart disease, based on this big review of studies.
