As people become more health conscious, as well as look for a product to blame for America's obesity epidemic, HFCS has come under a great deal of scrutiny recently, and many feel that it's the problem. However, there's very little (if any) scientific evidence to support that theory.
Chemically, HFCS is very similar to sucrose (table sugar), as both are comprised of similar ratios of fructose and glucose, and are metabolized in the same way.
While I certainly support more research in this area, there's no reason to think that it's any more or less healthy than table sugar.
You are completely wrong, sorry.
Sucrose (table sugar), is a 'disaccharide'. It is a complex sugar composed of two simple sugars, Glucose and Fructose, in a 1:1 ratio where 1 Glucose molecule has an alpha-beta linkage to a Fructose molecule.
Human bodies run on Glucose. It is converted to energy in the Krebs cycle of individual cells. Ingesting higher amounts of Glucose causes "blood sugar" (Glucose) levels to spike, because that is where it gets transported and processed. Insulin is involved in moderating this effect. Excess energy that is not immediately used is stored as fat for later use. This is important, keep reading.
Humans are able to break the alpha-linkage of Sucrose in our digestive tracts, and separate the two sugars (Glucose and Fructose).
The Glucose gets sent off through the bloodstream and processed by cells into energy. Excess energy is stored as fat around muscles (e.g. subcutaneous fat), and is what can give you flabby arms and a flabby ass.
The Fructose cannot be processed by the Krebs cycle, so it is filtered out of the blood by the liver where it is processed into fat directly. Note, it does NOT give you any energy directly, it goes straight to fat (which theoretically could be converted to energy later, but....) The fat that it builds up is "organ fat", around your internal organs. Particularly, you get a 'fatty liver'. Ever see somebody with muscular arms/legs, but a huge gut? Guys who look pregnant with a beer gut?
Organ fat leads to problems like high cholesterol (from a fatty liver), coronary artery disease, atherosclerosis, gallstones, and others.
So, Sucrose is 50% Glucose / 50% Fructose. On the other hand HFCS is 95% Fructose, 5% Glucose. (
HIGH-fructose corn syrup). For the same amount of sweetener, you're getting almost a double-dose of Fructose.
Is there any situation where Fructose is the preferred sweetener? Yes, sort of: for diabetics who don't produce enough insulin to process Glucose. They can use Fructose to get the sweetness and make their liver do the work, poorly. The reason I say "sort of" is that now that we have artificial sweeteners like Splenda (which is sucralose, a non-digestible sugar), there's no reason for diabetics to consume fructose as a sweetener.
NONE OF THIS is in dispute. Your dismissive assertion that there is 'very little scientific evidence' is inappropriate. HFCS is directly responsible for a significant portion of the health issues that Americans have today.
I personally do not consume any food that contains HFCS or partially-hydrogenated oils. It can be done, you just have to pay attention. It was a pain finding cranberry sauce without HFCS.... last year Costco had big jars of Ocean Spray "Homestyle" cranberry sauce, so I stocked up on a bunch of it.
] and apperently now there's commercials for corn syrup
