Sugar Scare: Why Calories May Be the Least of Your Worries About Sweeteners
That’s according to a new study out in the journal JAMA Internal Medicine that
found Americans who get 25 percent or more of their calories from added
sugar are nearly three times more likely to die of heart disease than
those who consumed less than 10 percent—the amount recommended by the
World Health Organization.
The study is the first of its kind to link added sugar consumption to death.
Head
researcher Quanhe Yang of the Centers for Disease Control and
Prevention looked at 15 years' worth of data gathered from 31,000 people
who participated in the National Health and Nutrition Examination Survey.
They found that 70 percent of adults exceed WHO’s recommendation that
added sugar be limited to under 10 percent of daily calories, making
them more likely to die of heart disease.
Whether the added sugar comes from high fructose corn syrup, beet or cane sugar, or something as natural as honey doesn’t matter—the study included all foods that were sweetened.
“What’s tricky is the FDA does not require manufacturers to put added sugar on the label,” says Rachael Johnson, spokesperson for the American Heart Association and University of Vermont professor of nutrition.
To avoid listing sugar as the first ingredient on the ingredient panel, Johnson says food makers often list five or six kinds of sugar separately instead. The FDA has been petitioned to address the problem, she says, but no action has been taken. And of course, naturally occurring sugars in fruit aren't flagged either.
“What
the study says is that eating too much sugar isn’t good for you. That’s
hardly news,” says Marion Nestle, New York University professor of
nutrition. But she says the study reinforces the benefits of limiting
added sugars.
“Just about
everyone would be healthier eating less sugar, but less is not the same
as none. Ten percent of calories for most people means 50 to 80 grams of
sugars a day, or 12 to 20 teaspoons. A bit more won’t raise the risk by
much. Soft drinks have slightly under a teaspoon of sugar per ounce, so
drinking less of them is a good first step,” says Nestle.
Indeed,
the study found that 37 percent of added sugar in our diets comes from
sugar-sweetened beverages, followed by grain-based desserts, fruit drinks, dairy desserts, and candy.
No
surprise, the beverage industry responded swiftly to the new study.
After taking credit for an overall decline in adult consumption of added
sugars thanks to the industry's increased focus on providing more low-
and no-calorie options, the American Beverage Association maintains the
study is flawed.
“Heart
diseases are a complex set of problems with no single cause and no
simple solution. When it comes to risk for heart disease, there is
nothing unique about calories from added sugars, or sugar-sweetened
beverages for that matter,” says the group in a statement.
“This is an observational study which cannot—and does not—show that
cardiovascular disease is caused by drinking sugar-sweetened beverages.”
But
Yang tells TakePart that the study isn't focused on only sweet
drinks—it examines all added sugars, including hidden sugars that
Americans consume.
"Most
previous studies have focused on sugar-sweetened beverages but not total
added sugar, and none of these studies have used national
representative samples to examine the relationship between added sugar
intake and cardiovascular disease mortality," says Yang.
