Fructose, what has been touted as “fruit sugar” for all these years, is truly where the blame lies in all this. Natural fruit sugar, from good sources like fruits and honey are acceptable in their true form, and have many healthy benefits, whether from the fruit or the honey itself. Corn is a grain, a grass, and even natural maize has its pitfalls, which will be discussed in a future post.
I could show you everything about Fructose from beginning to end, but since the focus here is on commercial produced HFCS, that is the part of the science I will show you. Here is what Wiki has to tell us about the health effects of fructose:
Fructose absorption occurs via the GLUT-5 (fructose only) transporter, and the GLUT2 transporter, for which it competes with glucose and galactose. A deficiency of GLUT 5 may result in excess fructose carried into the lower intestine. There, it can provide nutrients for the existing gut flora, which produce gas. It may also cause water retention in the intestine. These effects may lead to bloating, excessive flatulence, loose stools, and even diarrhea depending on the amounts eaten and other factors. For many people, fructose malabsorption is a major health concern.
 Metabolic syndromes
Excess fructose consumption has been hypothesized to be a cause of insulin resistance, obesity, elevated LDL cholesterol and triglycerides, leading to metabolic syndrome. Fructose consumption has been shown to be correlated with obesity, especially central obesity which is thought to be the most dangerous kind of obesity. A study in mice showed that a high fructose intake increases adiposity.
Although all simple sugars have nearly identical chemical formulae, each has distinct chemical properties. This can be illustrated with pure fructose. A journal article reports that, “…fructose given alone increased the blood glucose almost as much as a similar amount of glucose (78% of the glucose-alone area)”.
One study concluded that fructose “produced significantly higher fasting plasma triacylglycerol values than did the glucose diet in men” and “…if plasma triacylglycerols are a risk factor for cardiovascular disease, then diets high in fructose may be undesirable”. Bantle et al. “noted the same effects in a study of 14 healthy volunteers who sequentially ate a high-fructose diet and one almost devoid of the sugar.”
Fructose is a reducing sugar, as are all monosaccharides. The spontaneous chemical reaction of simple sugar molecules to proteins, known as glycation, is thought to be a significant cause of damage in diabetics. Fructose appears to be equivalent to glucose in this regard and so does not seem to be a better answer for diabetes for this reason alone, save for the smaller quantities required to achieve equivalent sweetness in some foods. This may be an important contribution to senescence and many age-related chronic diseases.
Oh, but that’s not all, and as I am pressed for time today, I will share the rest of these with you later. Simply put, commercial corn sugar is bad for you. Best not to use it. Take the time to read the labels, because you never know where it will turn up next. With the industry trying to get the name changed, we have to be more clever than they are to see what they are doing. Most of the readers of this blog are most likely clever enough to avoid the corn sugar poisons to know them for what they are. From to soda giants to the fast food drive-thrus, you know where the sticky sweet badness will be. Good luck in avoiding it, but with knowledge behind you, there will be no need for luck.
