A few years ago, I started having fast heart rate, palpitations, slurred speech, and difficulty to concentrate after eating certain foods (the first event occurred after eating Oreo cookies with whole milk). About a year later I discovered by reading food labels that these reactions were always preceded by consumption of high fructose corn syrup. E.g., if I drank Pepsi with regular sugar, nothing bad happened. If I drank Pepsi with HFCS, the symptoms appeared within minutes, and were very intense to a degree that left me unable to concentrate in my studies for about two hours. The Oreo cookies that preceded my first reaction contained HFCS.
I think [a few years ago] some of the HFCS factories were found to be leaving mercury in some of the sweetener, so that might be a possible explanation. But the normally produced HFCS contains a lot of starch-like material, besides the fructose and glucose, and I think that material would be able to cause allergic reactions.
Destiny said:What is so bad about HFCS? The GI is about same as sucrose and both are a mix of fructose and glucose?
Much of the current concern about the dangers of fructose is focussed on the cornstarch-derived high fructose corn syrup, HFCS. Many studies assume that its composition is nearly all fructose and glucose. However, Wahjudi, et al. (2010) analyzed samples of it before and after hydrolyzing it in acid, to break down other carbohydrates present in it. They found that the carbohydrate content was several times higher than the listed values. "The underestimation of carbohydrate content in beverages may be a contributing factor in the development of obesity in children," and it's especially interesting that so much of it is present in the form of starch-like materials.
Corn syrup is something to avoid, because manufactured foods always contain contaminants, but it's not mong the worst additives.
