Dietary guidelines recommend that healthy adults get no more than 2,300 mg of sodium a day, the amount in just 1 teaspoon of table salt (sodium chloride). People with hypertension, those middle-aged and older, and African-Americans should aim for less than that—no more than 1,500 mg. But the average American ingests 2,900 to 4,300 mg.
Our food experts hit supermarkets to ferret out products in which sodium might be a surprise. Among them:
Some fast-food fare also has surprising sodium levels. McDonald's Premium Caesar Salad with grilled chicken, for example, has 890 mg of sodium—without dressing. A large order of fries has 350 mg.
Lower-fat products can be higher in sodium than their full-fat counterparts. (When fat is removed, sodium is sometimes added to compensate.) A serving of Ruffles Original Potato Chips has 10 grams of fat and 160 mg of sodium, for example; the baked version, with 7 fewer grams of fat, has 40 mg more sodium.

You might be getting sodium, even if you don't see "sodium chloride" listed as an ingredient, in the form of disodium guanylate, disodium inosinate, sodium caseinate, sodium benzoate, sodium bicarbonate, sodium nitrite, and other combinations. Some of those ingredients are flavor enhancers; others are thickeners, preservatives, or texture enhancers.
