Cancer, fructose, HFCS.

Dr Anthony Heaney has found that pancreatic cancer gets fuel from both fructose and glucose, in two quite different pathways. This suggests that blocking one of the pathways might cut the risk of cancer.

The results came from experiments with human cancer cells in Petri dishes, but should apply in real life.

It is likely that the twin pathway finding applies to other cancers as well.

That’s the science. Then there is the press release from the University of California Los Angeles.

The source of fructose in the Western diet is high fructose corn syrup (HFCS), a corn-based sweetener that has been on the market since about 1970. HFCS accounts for more than 40% of the caloric sweeteners added to foods and beverages, and it is the sole sweetener used in American soft drinks.

Between 1970 and 1990, the consumption of HFCS in the US has increased over 1,000%, according to an article in the April 2004 issue of the American Journal of Clinical Nutrition.

“I think this paper has a lot of public health implications,” Heaney said. “Hopefully, at the federal level there will be some effort to step back on the amount of HFCS in our diets.”

HFCS is typically 55% fructose and 45% glucose. Sucrose – table sugar – is broken down by the stomach to its components – 50% fructose and 50% glucose. Fructose is the natural sweetener in honey and fruit.

Europe consumes almost no HFCS, and sweetened soft drinks are made with sucrose. Europe is far from obesity-free or cancer-free.

A recent study of UK consumption over the last 20 years found total sugar consumption per person was unchanged. Table sugar and sugar from cakes and biscuits had declined, while sugar in soft drinks had made up for this.

If you want to cut your risk of obesity or cancer, cut the empty calories of sweetened soft drinks, whether they are HFCS (US) or sucrose (Europe).

  1. Fructose that occurs naturally in fruit has not been found to be harmful. Honey
