Americans consume an average of about 22 teaspoons a day of added sugar, according to the National Cancer Institute. That type doesn't occur naturally—the way fructose does in fruit—and its calories might lack extra nutrients. A sensible daily limit of added sugar is more like 6 teaspoons for women and 9 for men, the American Heart Association says.
Sugar can plead not guilty to some accusations. Many studies have debunked the idea that it causes hyperactivity in kids, for example. But it does nourish the bacteria that cause cavities, and the AHA says that added sugar is associated with increased risks of high blood pressure and high triglyceride levels. A study published last year in the journal Cancer Epidemiology, Biomarkers & Prevention suggested that drinking an average of five sugar-laden soft drinks a week increased the risk of pancreatic cancer.(1) And it's probably not coincidental that the nation's obesity epidemic has progressed in step with increased sugar consumption.
The foods above, bought recently near our headquarters, are just a few in which sugar can hide. The cubes represent all sugar, added and natural, because labels don't list those separately. Our symbolic cube equals 1 teaspoon. The amount in real cubes might be less.
What you can do. Study nutrition facts and ingredients. Other names that signal sugar include dextrose, fruit-juice concentrate, glucose, malt syrup, maltose, molasses, sucrose, beet sugar, high-fructose corn syrup (the Corn Refiners Association has asked the Food and Drug Administration to change that to corn sugar), and evaporated cane juice. Other steps:
(1) The original version of this story reported that an epidemiological study last year found that drinking two or more sugar-laden soft drinks a week almost doubled the risk of pancreatic cancer. On further review, we realized that the epidemiological study that suggested a link between consumption of sweetened soft drinks and increased risk of pancreatic cancer was not conclusive. While the study's conclusion mirrored that found in some earlier studies, there are also studies that have found no effect of soft-drink consumption on the risk of developing pancreatic cancer. More research is needed in this area
