10 Heart-Healthy Rules to Live By

6 Read food labels

Always check the food label before purchasing or consuming any product, recommends Artinian, and avoid foods that are marked as high in calories, sodium, or saturated fat.

But be sure to do your math. Labels will list both serving size and how many calories and other nutrients there are in a serving, so a little multiplication or division may be necessary. “You can’t just assume that whole can is a serving,” Artinian says.
