Some sweet products, morning products and low-fat items contain high levels of salt even though they may not taste salty, according to an analysis of supermarket products by a consumer group.



Consumer Reports researched 37 brands available in America. Among the high sodium surprises uncovered by the analysis were Twizzlers black licorice (four strands have 200 milligrams of sodium), a Pepperidge Farm whole grain white bagel (440 milligrams of sodium) and Prego Heart Smart Traditional Italian Sauce (430 milligrams of sodium per half cup).

Some restaurant meals contain whopping amounts of salt, which is used as a preservative and to enhance flavor and texture. Chili’s fajita chicken quesadilla with rice and black beans, sour cream and pico de gallo has 5,300 milligrams of salt.

The test did find that nutritional labels are an accurate reflection of salt levels. In some cases, sodium is added to low-fat foods to compensate for lack of flavor, and checking the label is the only way to know.

Many items perceived to be salty contain less salt than some low-fat products, the testing found. For example, a quarter-cup of Planters mixed salted nuts contains 110 milligrams of sodium, less than half the sodium in seven Kraft Snackables cheddar and Monterey Jack reduced-fat cheese cubes, which have 270 milligrams of sodium.

Sodium increases the possibility of developing high blood pressure and related cardiovascular problems, and federal dietary guidelines recommend limiting salt intake to 2,300 milligrams a day. The average American consumes 2,900 to 4,300 milligrams of sodium a day.

Sodium in food comes from ingredients other than regular salt, including mono sodium glutamate, baking soda, sodium nitrate and other additives; only about 10 percent of the sodium individuals consume occurs naturally.

The American Medical Association has estimated that 150,000 lives could be saved each year if people in the U.S. lowered their sodium intake in half, and the Center for Science in the Public Interest, a consumer watchdog group, has petitioned the Food and Drug Administration to regulate salt in foods.

According to the center, although some producers have lessened sodium in their products in recent years, amounts have spiked in other products over the same time period. A serving of french fries at Hardee’s, the fast food chain, contains three times as much sodium as it did in 2005, according to C.S.P.I.

The salt lowers in some places and increases in others "basically cancel each other out, said C.S.P.I. executive director Michael F. Jacobson. Sodium levels may vary in a given product from brand to brand, but overall salt levels haven’t changed, he added.

The consumer-watchdog organization also conducted a taste test of lower-sodium versions of foods that are normally high in sodium. The most common ones were Dietz & Watson Gourmet Lite turkey breast (with the skin on), with 240 milligrams of sodium per two-ounce serving, and the Silver Palate Salad Splash Balsamic Country salad dressing, which has 15 milligrams of salt in 2 tablespoons.
