Foods that might have added sugar or another sweetener like high-fructose corn syrup as an ingredient are pictured Wednesday, March 4, 2015, in New York. New guidelines published by the World Health Organization on Wednesday say the world is eating too much sugar and people should slash their sugar intake to just 5 to 10 percent of their overall calories.

NEW YORK — Health officials say people should eat less sugar. But that’s easier said than done.

Anyone who has tried cutting down on sugar knows to avoid cookies, sodas and candy. But sugar can be hidden in lots of other common packaged foods.

The World Health Organization finalized guidelines recently saying people should keep intake of added sugars to just 5 to 10 percent of overall calories, which translates to about 25 to 50 grams of sugar a day for most people. The guidelines don’t apply to naturally occurring sugars in fruits, vegetables and milk, since they come with essential nutrients.

In the U.S., adults get about 11 to 15 percent of their calories from sugar; the figure for children tops that at about 16 percent. By comparison, sugar intakes ranges in Europe from about 7 percent in Hungary to nearly 25 percent in Portugal.

But many people aren’t aware of how much sugar they’re eating every day. In fact, that’s one reason the U.S. Food and Drug Administration is proposing the first overhaul of nutrition labels in two decades. In addition to highlighting the number of calories per serving in a bigger, bolder font, the new proposed labels would also for the first time list sugars that are added by manufacturers.

In the meantime, though, companies don’t currently disclose how much of the sugar listed in the nutrition panels of their products are from added sugars.

Here are examples of foods that might have added sugar or another sweetener like corn syrup:

Soup. Even savory varieties have sugar. Progresso’s Rich & Hearthy Beef Pot Roast has about 1 teaspoon of sugar per serving.

Yogurt. Some sugar occurs naturally but companies add sweeteners too. Chobani’s 0% fat Greet yogurt in black cherry has about 4 teaspoons of sugar per container.

Peanut butter. Skippy’s Super Chunk variety lists almost 2 teaspoons of sugar per serving.

Frozen meals.Just because it’s not dessert doesn’t mean it doesn’t have added sugar. California Kitchen’s BBQ Chicken microwavable pizza has almost 2 teaspoons of sugar in a single-serving pie.
