The HFCS-Cancer Connection

A recent study on mice led by researchers at Baylor College of Medicine and Weill Cornell Medicine, and published in the Journal Science in March 2019 found that consumption of HFCS may well make people more prone to develop colorectal cancer. (This particular study was supported by the National Institutes of Health, Stand Up 2 Cancer, the Cancer Prevention and Research Institute of Texas and the National Cancer Institute.)

Obesity, the study’s authors pointed out, “increases an individual’s risk of developing many types of cancer, including colorectal cancer” and “one of the factors driving the rise in obesity rates is thought to be the use of high-fructose corn syrup as a sweetener in soft drinks.” But their findings went beyond that, indicating that consuming only a “modest amount” of HFCS—the equivalent in humans of consuming about 12 ounces daily of a “sugar-sweetened beverage” (by which they specifically meant one containing HFCS)—accelerates the growth of intestinal tumors of the disease in mice without their having become obese.

“These results suggest that when the animals have early stage of tumors in the intestines—which can occur in many young adult humans by chance and without notice—consuming even modest amounts of high-fructose corn syrup in liquid form can boost tumor growth and progression independently of obesity,” said Dr. Jihye Yun, assistant professor of molecular and human genetics at Baylor.

Using cutting-edge methodology, the research team also claimed to have found a “direct molecular mechanism,’ in the phrase of another team member, Dr. Lewis Cantley, by which HFCS consumption promotes the growth of such tumors—something not done by previous studies.

“This study revealed the surprising result that colorectal cancers utilize high-fructose corn syrup, the major ingredient in most sugary sodas and many other processed foods, as a fuel to increase rates of tumor growth,” said Cantley, a professor of cancer biology in medicine and director of the Sandra and Edward Meyer Cancer Center at Weill Cornell Medicine.9

The 2019 study reinforced one done at UCLA nine years earlier, which concluded that pancreatic cancers use fructose to activate a key cellular pathway that in turn triggers cell division, helping the cancer to grow more quickly and that “cancer cells can readily metabolize fructose to increase proliferation.”
