Remember this...those ads on TV (of which I have seen a couple) are paid for by the soda and corn refining industry, so their claims are immediately
biased in favor of the lack of evidence of harmful affects by HFCS. One of the chief arguements against HFCS is that due to the fact that it is less
expensive to produce than cane sugar, it is more widely consumed, thereby contributing mainly to the ongoing obesity of Americans (specifically sited
because every site I have been to contains this reasoning). Fructose is transported and blended from its liquid form, also making it more desireable
than cane sugars.
HFCS contains varying amounts of natural sugars in its component makeup, depending on the desired outcome. The higher the fructose content, the
cheaper the product. This also affects the "sweetness" factor, which is a completely objectable measure, since sweetness levels are very much
individually taste oriented.
Over the years, several companies that have used HFCS in their products have been sued when they advertise their products as "All Natural". This is
because the fructose that ends up in the consumer product is not an all natural product. By the time it is introduced into consumer products, corn
syrup (origin of fructose) has undergone an enzymatic process to increase the fructose levels in the blend. It is then mixed with glucose to form
HFCS.
I gathered a most of this information across several websites.
google High Fructose Corn Syrup
Be warned. The information found across the websites that come up on the search above have a very wide array of "facts" about HFCS. From one site
to the next, the information changes. What is fact on one site, is myth or dismissed on another. I went through several of them before just posting
clinically based on the chemical makeup and processing, which seems to be about the only thing that all of the sites agree on.
Personally, I do drink several sodas a day. I like the taste. However, when I use a sweetner at home, it is and always has been pure granulated cane
sugar. The sweetness factor is noticeably different, but so is the way I feel in the short run after consuming it versus soda.
Beyond the diabetic and obesity factors, I dont think that HFCS (in strict moderation) is necesarily bad for your health. I think it is more the idea
that it is cheap, widely readily available, and satisfies even the most powerful sugar rush desire. The downside from my own experience is how HFCS
aids in the burst energy -> energy crash scenario. I think anyone with hypertension or ADHD should most assuredly have their sweetner intake closely
monitored for that reason alone.
