Limit Processed Foods

You may have to eat a frozen meal now and then, but don’t make it a habit. Certain packaged foods can be loaded with sodium and other preservatives. The FDA suggests sticking to no more than 2,300 milligrams of sodium per day—that’s one teaspoon of salt. A typical frozen entrée can easily pack more than 30% of your sodium intake for the day, so check the label before plopping one in your grocery basket.
