Carbs and glycaemic load linked to poor prognosis of colon cancer

The observational study of 1011 patients, who self-reported their diet, examined the influence of glycaemic load, glycaemic index, fructose and carbohydrate intake on recurrence and mortality. The association appeared greatest in patients who were overweight and obese.

“Given that patients who consume high glycaemic loads or carbohydrates after cancer diagnosis may have consumed a similar diet before diagnosis, we cannot exclude the possibility that individuals with these dietary exposures acquire tumours that are biologically more aggressive,” the authors said.
