- New research uncovers a link between fructose and breast cancer.
- 50 to 58 per cent of mice on fructose- and sucrose-enriched diets developed mammary tumours in six months.
- These diets also led to significantly higher rates of the cancer spreading to the lungs.
A new study has found that fructose has been found to increase the risk of breast cancer.
Scientists at the MD Anderson Cancer Center in Texas found that 50 to 58 per cent of mice on fructose- or sucrose- (half fructose, half glucose) enriched diets developed mammary tumours in six months, compared to 30 per cent on a starch-control diet. The cancer also grew faster and had significantly higher rates of spreading to the lungs.
This is the first study to investigate the direct effect of consuming sugar on the development of breast cancer (albeit using animal models).
It’s interesting to note the unique role of fructose in this study, which is the sugar we quit on our 8-Week Program. Like all cells in the body, cancer needs glucose to thrive, leading some to posit that a diet low in refined or simple carbohydrates may prevent and help treat cancer. But co-author Lorenzo Cohen, Ph.D, said that “we determined that it was specifically fructose, in table sugar and high-fructose corn syrup, ubiquitous within our food system, which was responsible.”
Of course, we’ll need a further proof to determine the mechanisms behind these results. In the meantime, however, it really doesn’t seem like a bad idea to cut down on those refined carbs and sugars if we’re serious about our health.
What do you think? Is there a connection between sugar and cancer, or is the jury still out?
