- Pizza. The UCSF researchers say its No. 1, thanks to sodium in the crust, sauce, cheese and in meat toppings like pepperoni, sausage and ham. Two slices of one popular pizza chain’s meat-topped pizza deliver over 1,600 mg of sodium.
- Bread. Two slices of whole-wheat bread pack about 240 mg of sodium (it varies by brand, of course) — close to the 270 mg in a medium-sized bag of fast-food fries.
- Deli meat and cheese. Two ounces of Virginia ham pack 450 mg of sodium. Pair it with two slices of bread, a dab of mayo and a slice of cheese and you’ve got more sodium than a fast-food cheeseburger.
- Pasta dishes. One cup of canned ravioli and sauce has nearly 1,000 mg of sodium — more than a drive-through double hamburger. A cup of macaroni and cheese has more than 500 mg.
- Soup. One cup of chunky chicken noodle soup from a can packs 889 mg of sodium — as much as three big handfuls of barbecued potato chips.
- Breakfast cereal. A cup and a half of corn flakes has about 500 mg of sodium.
What can you do? About 65 percent of the sodium we eat comes from foods we buy at the supermarket or at convenience stores. Check the nutrition facts on the label first — and try out lower- or no-sodium versions of the foods your family eats most often.
