Eliminating sugar won’t stop relapse

DEAR DR. ROACH: A year ago, I was diagnosed with colon and liver cancer, and was treated with chemotherapy. The last chemo was in June 2016. My posttreatment CT scans have shown me to be negative for cancer.

At the beginning of treatment, I read in clinic material that “sugar” is the No. 1 cancer-causing food. At that point, I eliminated sugar from my diet. My doctor was noncommittal about sugar.

What are your thoughts on this? Also, is honey the same as granulated sugar? I believe honey is healing.

ANSWER: Congratulations on being cancer-free so far. I hope this turns out to be a cure.

While it is true that cancer cells use sugar for energy, most of the cells in your body use sugar for energy, and your brain is absolutely dependent on sugar for energy (whereas most cancer cells can use many sources of energy, including protein and fat).

It is not possible to completely reduce blood sugar (which would be seen by any cancer cells) even by reducing all sugar and other carbohydrates in the diet to 0, as your body can make sugar.

More importantly, many healthy foods that have been shown to help fight several cancers and reduce recurrence, such as fresh fruits and vegetables, have naturally occurring sugars.

Certainly, it is not healthy to consume large amounts of any kind of sugar, even honey. Honey is not exactly the same as table sugar: Honey is a combination of two simple sugars, fructose and glucose; whereas table sugar, sucrose, is a single compound containing those same two simple sugars linked together.

In the intestine, table sugar is quickly broken down into the same two simple sugars that are in honey. Modest amounts of sugars (the American Heart Association recommends a limit of 37.5 grams of added sugar for men, 25 grams for women, whereas the World Health Organization recommends only 25 grams for both — about 6 teaspoons) are not going to increase your risk of the cancer recurring.
