The Hidden Ingredient That Can Sabotage Your Diet


One hundred and fifty-six pounds. That’s how much added sugar Americans consume each year on a per capita basis, according to the U.S. Department of Agriculture (USDA). Imagine it: 31 five-pound bags for each of us.

That’s not to say that we get most of the sugar in our diets directly from the sugar bowl. Only about 29 pounds of it comes as traditional sugar, or sucrose, according to The Sugar Association, a trade group of sugar manufacturers. The rest comes from foods.

Of course, those foods include things like candy, soda, and junk food. But plenty of sugar is hiding in places where you might not expect it.

Some types of crackers, yogurt, ketchup, and peanut butter, for instance, are loaded with sugar — often in the form of high-fructose corn syrup, or HFCS. Use of this sweetener has increased 3.5% per year in the last decade, according to the World Health Organization (WHO). That’s twice the rate at which the use of refined sugar has grown.

Where is all that sugar going? In the U.S. diet, the major source of “added sugar” — not including naturally occurring sugars, like the fructose in fruit — is soft drinks. They account for 33% of all added sugars consumed, says Kristine Clark, PhD, RD, a spokeswoman for the Sugar Association. Clark is also director of sports nutrition in the athletic department of Penn State University.

According to the USDA, sweetened fruit drinks account for 10% of the total added sugars we consume. Candy and cake come in at 5% each. Ready-to-eat cereal comprises 4% of the total. So do each of these categories: table sugar and honey; cookies and brownies; and syrups and toppings.

The biggest chunk, making up 26% of added sugars, comes from a variety of prepared foods like ketchup, canned vegetables and fruits, and peanut butter.

Another high-sugar category? Low-fat products, which may not be as good for your diet as you think. Some contain plenty of sugar to make up for the lack of tasty fat.

“People are often surprised that a low-fat product may not be that different in calories” than regular products, says Connie Crawley, diabetes and obesity, not anything inherently unhealthy about sugar itself,” says Jule Anne Henstenberg, RD, director of the Nutrition Program at La Salle University in Philadelphia.

“Foods with a lot of sugar taste good, so we eat can eat too much of them,” she says. “The one area where this fact stands out is in drinks. In the last 20 years, we’ve seen an explosion of sugared drinks in the daily calories. In a 2,000-calorie-a-day diet, that’s just 200 calories — or eight heaping teaspoons of table sugar at 25 calories each. A single can of regular soda, with the equivalent of 10 teaspoons, would put you over.

But some take issue with the reports of our rising sugar consumption. The Sugar Association, a trade group of sugar producers and growers, maintains that the average American consumes no more than 1.6 ounces, or about 9 teaspoons, of added sugar per day.

When the USDA says that we each consume 150 pounds of sugar a year, that figure refers to ‘economic consumption,'” says Clark. “That’s an estimate of all caloric sweeteners available for sale in a year, but only a fraction of that is for human consumption. The rest goes into export markets, pet foods, alcohol manufacturing, waste and storage, and the like.”

No doubt, national estimates of food consumption are subject to much interpretation. But in the real world of everyday eating decisions, what foods should we avoid and what foods should we enjoy to maintain healthy weight?

“Our body fat depends on total calorie intake, not on a particular source of calories,” says Crawley. “Of course the tip of the food pyramid [the category that includes sugar and oil] is where most of the empty calories are found, so minimizing choices from there will help.”

If you want to avoid hidden sugar:

  • Read food labels. Ingredients are listed in order of volume, so anything with sugar, corn syrup, glucose (or, in general, words ending in “-ose”) near the top of the list is likely to be high in sugar.
  • When you do choose a product with added sugar, watch your portion size.
  • Simply avoid processed foods as much as you can — especially sodas and other sweetened beverages.

And what about artificial sweeteners? While they can be useful in weight maintenance, use them sparingly, says Crawley. All sweeteners have little nutritional value,” she said. “I prefer to use a minimum of all of them.” That’s great, but what if you still crave sweets? Fresh fruit is always your best bet, but if it just won’t do the trick, the Sugar Association has a few suggestions:

  • Angel food cake topped with fruit.
  • Frozen fruit ices and sorbets.
  • Low-fat frozen yogurt.
  • Fruit shakes made with low-fat milk.
