HFCS.. What??

Studies

Part of the concern over fructose arises from animal testing in which the injection of fructose directly into the brain of rats led to increased eating and subsequent research in mice seemed to confirm this effect. Re-examination of the results suggested that the results in rodents would have little meaning in humans due to the dosage given (equivalent to a 75 kg human consuming 660 grams of fructose, whereas a normal daily intake is approximately 50 grams) and the strict control over the amount of fructose that crosses the blood–brain barrier.[1] Subsequent testing with humans using both short- and long-term experiments found no important differences between the consumption of HFCS versus other sugars.[1] Most of the studies linking fructose consumption to higher blood triglycerides have been in rodents through mechanisms different from those in humans, and therefore it is unlikely that high-fructose diets would have comparable effects in humans. Tests in humans suggest that for people with insulin resistance, diets with 50 grams or more per day (high consumption) may result in elevated triglycerides, but there is no effect with normal levels of fructose consumption.[1]

Epidemiological research has suggested that the increase in obesity is linked to increased consumption of sugars and/or calories in general, and not due to any special effect of fructose alone.[1]
Other issues

Consumption of HFCS has been associated with non-alcoholic fatty liver disease, as it is thought that fructose may cause increased fat deposits in the abdomen[10] though it has also been suggested that this association is not unique to fructose and may be due to glucose consumption as well.[11]

The presence of carbonyl compounds found in HFCS-containing beverages has been suggested as a contributor to poor health and problems for people with diabetes, though this concern is unfounded as HFCS is of no more concern than other sources and the compounds are produced endogenously by the body.[12]

High fructose consumption has been linked to high levels of uric acid in the blood, though this is only thought to be a concern for patients with gout.[1]

The possibility that significant consumption of products containing high fructose corn syrup with detectable levels of mercury could result in neurotoxicity was raised by studies in 2009.[13][14][15] In 2011 the Corn Refiners Association announced that “no mercury or mercury-based technology is used in the production of high fructose corn syrup in North America.”[16] By the end of 2012, most chlor-alkali plants in the United States had phased out older "mercury cell" technology linked to mercury contamination of HFCS, except for two chlor-alkali plants - one in Ohio and one in West Virginia, run by ASHTA Chemicals and PPG Industries, respectively.[17][18][19] Mercury cell technology is still widely used outside of the United States and there are no restrictions on importing mercury-grade caustic soda for use in HFCS production.[15][20]

HFCS consumption can be problematic in those with fructose malabsorption.[21]
