Butter. Yogurt butter. Olive-oil margarine. There’s no end to the variety of spreads available today, Cleveland Clinic reports.  How do you know which ones are healthy for your heart?

You can’t go by total fat. If most of the fat is heart-healthy monounsaturated or polyunsaturated fat, that’s a good thing. But there is even a miniscule amount of trans fat, that’s a problem.

Heart & Vascular Institute dietitians Julia Zumpano, RD, LD, and Kate Patton, RD, LD advice: for heart health, choose margarine with no more than 2 grams of saturated fat and 0 trans-fat.  Replacing all saturated fat in your diet with monounsaturated or polyunsaturated fat can lower bad cholesterol.

If you can’t give up butter and don’t have heart disease, make sure you aren’t getting more than 10-15 grams of saturated fat per day.
