"Here’s where the myth that sugar fuels cancer was born: if cancer cells need lots of glucose, then cutting sugar out of our diet must help stop cancer growing, and could even stop it developing in the first place. Unfortunately, it’s not that simple. All our healthy cells need glucose too, and there’s no way of telling our bodies to let healthy cells have the glucose they need, but not give it to cancer cells.

There’s no evidence that following a “sugar-free” diet lowers the risk of getting cancer, or boosts the chances of surviving if you are diagnosed."

Eating a heathy diet can reduce the risk of getting cancer and the risk of recurrence. Less sugar is usually part of a health diet. But sugar does not cause cancer.

Have you been diagnosed with cancer?

Cancer has been around far longer than added sugar in the diet. The question being looked at is "Does cancer feed on sugar more than any other carbohydrate?"
