The FDA’s recommendation for adults is 2,400 mg of sodium per day or less—the equivalent of a teaspoon of table salt. If a food has 5 percent or less of your daily sodium, it’s a low-sodium food. If it has 20 percent or greater, it is high in sodium.
75% of sodium in the American diet comes from packages and restaurant foods
11% of sodium comes from salt added at the table or in cooking
Potassium helps blunt the effect of sodium on blood pressure, so make sure you’re getting enough. The recommended minimum daily intake is 4,700 mg—a number that 98 percent of Americans are not meeting. Beans, yams, raisins, almonds, and fish are all good sources.
