Study suggests US Dietary Guideline for upper limit of sugar consumption is too high
A recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM) found that adults who consumed high fructose corn syrup for two weeks as 25 percent of their daily calorie requirement had increased blood levels of cholesterol and triglycerides, which have been shown to be indicators of increased risk for heart disease.
The American Heart Association recommends that people consume only five percent of calories as added sugar. The Dietary Guidelines for Americans 2010 suggest an upper limit of 25 percent or less of daily calories consumed as added sugar. To address this discrepancy in recommended consumption levels, researchers examined what happened when young overweight and normal weight adults consumed fructose, high fructose corn syrup or glucose at the 25 percent upper limit.
"While there is evidence that people who consume sugar are more likely to have heart disease or diabetes, it is controversial as to whether high sugar diets may actually promote these diseases, and dietary guidelines are conflicting," said the study's senior author, Kimber Stanhope, PhD, of the University of California, Davis. "Our findings demonstrate that several factors associated with an elevated risk for cardiovascular disease were increased in individuals consuming 25 percent of their calories as fructose or high fructose corn syrup, but consumption of glucose did not have this effect."
In this study, researchers examined 48 adults between the ages of 18 and 40 years and compared the effects of consuming 25 percent of one's daily calorie requirement as glucose, fructose or high fructose corn syrup on risk factors for cardiovascular disease. They found that within two weeks, study participants consuming fructose or high fructose corn syrup, but not glucose, exhibited increased concentrations of LDL cholesterol, triglycerides and apolipoprotein-B (a protein which can lead to plaques that cause vascular disease).
"These results suggest that consumption of sugar may promote heart disease," said Stanhope. "Additionally our findings provide evidence that the upper limit of 25 percent of daily calories consumed as added sugar as suggested by The Dietary Guidelines for American 2010 may need to be re-evaluated."
Also working on the study were: Andrew Bremer, Guoxia Chen, Tak Hou Fong, Vivien Lee, Roseanne Menorca, Valentia Medici, Peter Havel and Nancy Keim of the University of California, Davis; Katsuyuki Nakajima and Takamitsu Nakano of Otsuka Pharmaceutical Co. in Tokyo, Japan; and Yasuki Ito of Denka Seiken Co. in Tokyo, Japan.
The article, "Consumption of fructose and high fructose corn syrup increase postprandial triglycerides, LDL-cholesterol, and apolipoprotein-B in young men and women," appears in the October 2011 issue of JCEM.

Yes, and I'm sure the results would be the same with good old cane sugar as 25% of a person's diet.
I guess honey is out.
Back to Splenda.
high fructose corn syrup is lethal.
it enters the cells faster than other sugars.
the work on it began in the u.s. in the ‘50’s,
and then continued in the early ‘70’s in japan.
it first appeared in health food stores; i guess the idea
was to get the “health conscious” to adopt it.
then, it spread into everything. now in ketchup.
truvia is stevia-a natural sweetener that tastes bitter with the bitter taste removed.
truvia is found in supers and wal-mart has the best price.
It is 1.5 hours long but it is well worth it! He demonstrates how fructose, either from HFCS or sugar, does the same to our bodies as ethanol. He also shows how baby formula is essentially a milkshake for infants. The doctor uses all medically sound data. There is nothing in this for him to tell us not to eat fructose.
I just bought 2 lb. of bing cherries, and eat a lot of grapes.
One of our local tv stations reported on this. The news reader referred to it only as “sugar”, not the specific types of sugar that was used in the study. I just shook my head; I get so tired of shoddy reporting.
