(DAVIS, Calif.) -- Despite the American Heart Association's recommendation that people consume only 5 percent of their daily calories in added sugars, the Dietary Guidelines suggest an upper limit of 25 percent. But, as a new study released on Thursday suggests, the latter limit may be too high.
Researchers at the University of California, Davis examined the effects of eating 25 percent of daily calories as either fructose or glucose, which are both types of simple sugars. They found that within two weeks, eating high levels of fructose -- but not glucose -- resulted in an increase in bad cholesterol and other fats that can contribute to plaque formation in blood vessels.
The authors of the study, which was published in the Journal of Clinical Endocrinology & Metabolism, say that “these results suggest that consumption of sugar may promote heart disease [and] that the upper limit of 25 percent...may need to be re-evaluated.”
