The Details About the Sugar Bowl

Posted on August 27, 2015

As I sit and watch my toddler crunch her way through a rootbeer flavored Dum Dum sucker, I can’t help but think “no way” when she asks, “more, mommy?”

What is it that causes so many of us to see sugar in a bad light? Toddlers sure love it.  And I know that I love the taste of it too. I even love the smell of it baking and the sight of it caramelized on the top of a crème brulee. 

As sugar and sugar sweetened foods became more accessible—and activity levels decrease—we’ve learned that sugar isn’t the best for us. High consumption of sugar sweetened foods has been linked to excess weight gain, and carrying excess weight has been linked to diabetes, heart disease, high blood pressure and cancer. 

Excess Sugar Consumption and Health

Excess sugar consumption can contribute to higher calorie intake and subsequent undesirable weight gain. This is a vicious cycle that can increase your risk of cancer, secondary cancers and cancer recurrence. Consuming a diet high in sugar sweetened foods and beverages also increases insulin levels in the body, which in addition to obesity, can create a more cancer friendly environment.

For these reasons, those who have been diagnosed with colorectal cancer learn quickly from friends, family members, websites, magazines and many other places that sugar should be avoided.  I want to help you understand the link between sugar consumption and cancer because it is not black and white. Instead, it is really a grey area that takes some explaining. And of course, I want to help you learn the healthful way to include carbohydrates in your diet.

Does Sugar Feed Cancer?

Sugar does not “feed” cancer cells in any more than it “feeds” the other cells in our body. We have not yet learned how to feed the normal cells in our bodies and starve the cancer cells. This is because every cell in our body needs energy from some source. Naturally, our cells prefer simple carbohydrates, or sugar—the basic building block of carbohydrates—for energy. We eat food and it gets broken down into tiny particles that enter the bloodstream. These tiny particles, or simple carbohydrate, are removed from the bloodstream and used by all cells to create energy. It doesn’t matter if they are normal cells or cancer cells. They all utilize the food we consume.

Many cancer patients mistakenly avoid all sugar and carbohydrate in fear that they are doing harm by eating them. If we choose to consume an extremely reduced sugar and carbohydrate diet, our body will convert fat and protein into a form of sugar to feed our cells.  This can be very taxing on the body. When your body is fighting cancer, it needs all the necessary tools to do its best to repair and heal tissue and an extremely low carbohydrate is not the answer.

So What is Best to Eat?

The best way to supply your body with the wide variety of nutrients that it needs is to consume a mostly plant-based diet that includes a variety of healthy choices. 

Here are some useful tips:

  • Limit concentrated and refined sugar from candy, cake, cookies, sodas and sugar sweetened beverages because they are empty calories without any nutritional benefit
  • Choose more whole grain and complex carbohydrates from whole grain breads, rice, cereals, pasta, beans and legumes
  • Choose a variety of fruits and vegetables* which contain natural sugar along with beneficial antioxidants, fiber and plant chemicals

*If you are a colon cancer patient who has difficulty consuming fiber, a modified plant-based diet is still acceptable.

    The common cells of the body can run on ketones while many cancer cells cannot. The brain is the only part of the body that requires carbohydrates, entirely within the liver’s capacity to synthesize via gluconeogenesis.

    Unfortunately “many” does not include “all” cancers.

    Look for “Tripping Over the Truth” by Travis Christofferson. It has a detailed history of cancer treatments as a genetic disease and looks into current research showing that some (again, not all) cancers are a metabolic disease.

    I will share this information with the GI support that I facilitate at The James. Thanks for the information.

    I really wanted to post this article on sugar & cancer to my FB friends–survivors and those not yet affected…there is no fb logo to click on. Can we think about this? Spreading news to many who are not CCA’ers may also help keep the diagnoses down thru education and help others who are not yet members…jut a thought! Jo-Ellen

    Thank you so much for this article! I see well-intentioned but misinformed people sharing “sugar feeds cancer” everywhere.

  5. Chip Powers says:

    This message is woefully misguided. The ‘science’ behind sugar feeding cancer is actually due to the spikes in IGF-1 growth hormone, which can feed cancer that is already present. The goal is to avoid IGF and insulin blood spikes, which are caused by blood sugar spikes – i.e. avoiding the sugar level spikes, not avoiding sugar altogether (which of course would be misguided).

    Here’s a link to the ‘science’:

    This is just one of literally thousand of evidence-based links on the topic. Next time please simply google “igf-1 and colon cancer” before publishing a misguided/misleading article like this.

    Anyway, just my two cents.
