Heat Forms Potentially Harmful Substance in High-fructose Corn Syrup

Ack! HFCS fed to bees? Another reason to ONLY BUY ORGANIC:

Newswise — Researchers have established the conditions that foster formation of potentially dangerous levels of a toxic substance in the high-fructose corn syrup (HFCS) often fed to honey bees. Their study, which appears in ACS’ bi-weekly Journal of Agricultural and Food Chemistry, could also help keep the substance out of soft drinks and dozens of other human foods that contain HFCS. The substance, hydroxymethylfurfural (HMF), forms mainly from heating fructose.

In the new study, Blaise LeBlanc and Gillian Eggleston and colleagues note HFCS’s ubiquitous usage as a sweetener in beverages and processed foods. Some commercial beekeepers also feed it to bees to increase reproduction and honey production. When exposed to warm temperatures, HFCS can form HMF and kill honeybees. Some researchers believe that HMF may be a factor in Colony Collapse Disorder, a mysterious disease that has killed at least one-third of the honeybee population in the United States.

The scientists measured levels of HMF in HFCS products from different manufacturers over a period of 35 days at different temperatures. As temperatures rose, levels of HMF increased steadily. Levels jumped dramatically at about 120 degrees Fahrenheit. “The data are important for commercial beekeepers, for manufacturers of HFCS, and for purposes of food storage. Because HFCS is incorporated as a sweetener in many processed foods, the data from this study are important for human health as well,” the report states. It adds that studies have linked HMF to DNA damage in humans. In addition, HMF breaks down in the body to other substances potentially more harmful than HMF.

I'm also happy to quote, from the longer article: There appears to be a dearth of knowledge on the thermal effects of the kinetics of HMF formation in HFCS. Published research in the area appears to be limited to a single paper reported by Korean investigators (11)

So now there is harm in even syrup...well, besides the fact that its mostly sugar, which is pretty bad for you generally...but if you heat it its even WORSE!

Is there anything safe to eat these days anymore? Seems we have to watch everything now just to make sure it won't harm us or our kids.

So processed sugars that are heated are even more harmful. Wow! No more hot cinnamon rolls I guess...:)

Thanks for the info.
