Americans, on average, eat 3,400 milligrams of sodium in a day, about 1,000 mg more than we should. And if we cut that much out of our daily diets, we’d lower our risk of heart disease by up to 9 percent, according to a study in the New England Journal of Medicine. Restaurant foods and processed foods both tend to be very high in sodium, so a key step in lowering your sodium intake is to cook at home using fresh ingredients instead. One idea to cut back: Try eating out less and cooking more at home using fresh ingredients instead. And try boosting flavor with herbs and spices rather than salt.
