High Fructose Corn Syrup and Diabetes, What Should You Do
When it comes to type 2 diabetes and sugar, there is a not-so-sweet battle going on, and the fight is over high fructose corn syrup. The findings of a new study published in Global Public Health has fueled the fury by suggesting that countries with a higher availability of high fructose corn syrup (HFCS) in foods have a higher prevalence of type 2 diabetes.
What's wrong with high fructose corn syrup?
The answer to this question depends on who answers it. (Also check out the "High Fructose Corn Syrup Studies" below.) If you ask corn producers and the Corn Refiners Association, for example, they'll say there's nothing wrong. According to Audrae Erickson, president of the Corn Refiners Association, "There is broad scientific consensus that table sugar and high fructose corn syrup are nutritionally and metabolically equivalent."
Some scientists agree with this basic idea. Marion Nestle, PhD, MPH, professor of food, nutrition studies, and public health at New York University and a well-known author, noted that the new study is "based on a questionable and highly debatable premise: that high-fructose corn syrup is significantly different in its physiological effects from sucrose, or table sugar."
It's true that both high fructose corn syrup and table sugar are a combination of two simple sugars (fructose and glucose), which suggests they should have similar effects on the body. However, the lead author of the new research, Michael I. Goran, PhD, co-director of the Diabetes and Obesity Research Institute at the Keck School of Medicine at the University of Southern California in Los Angeles, believes that it is more complicated.
The fact is, table sugar consists of about 50 percent fructose and 50 percent glucose. When it comes to high-fructose corn syrup, the mixture is a bit of a mystery since the percentages are not revealed on food labels. However, the mixture is believed to range from 42 to 55 percent--or higher--for fructose.
In fact, Goran reported that he found fructose levels in beverages sweetened with HFCS ranging up from 47 percent to 65 percent. So if the fructose percentage is higher than 50 percent, could it have a negative effect on diabetes?
That remains to be seen. Goran noted that their study finding "raises a lot of questions about fructose," even though it does not establish that HFCS causes diabetes. What does his study show?
