Refined Sugar Causes Cancer

The Domino Effect of Cancer

The statement that refined sugar causes cancer may seem to you to be overly aggressive. Allow me to modify it. I was too conservative.

Refined sugar is a cause of cancer; a hindrance to cancer treatment and recovery; and, increases the risk of cancer recurrence.

In an interview on 60 Minutes, Lewis C Cantley, PhD, director of the Cancer Center at Beth Israel Deaconess Medical Center at Harvard Medical School, said that when we eat or drink sugar it causes a sudden spike in the hormone insulin. This spike in insulin can serve as a catalyst to fuel certain types of cancers. According to Cantley as much as 80% of all cancers are driven by factors that work to enhance or mimic the effect of insulin on the incipient tumor cells.

Cantley is a highly renowned cancer researcher. He is acclaimed for his discovery and study of the enzyme PI3k – a specific insulin-signaling gene responsible for the insulin/cancer connection.

If you or a loved one have been diagnosed with cancer, you have probably learned of the connection between cancer and the mutation of genes that are part of your genetic code.

Carcinogens and possibly inherited mutated genes create cells in your body that have a predisposition toward cancer. According to Cantely in 80% of cancers, once the necessary genes have mutated, there is one other condition that must be present for the cell to become cancerous – insulin resistance.

The mutation of the genes is like setting up a row of dominoes. To set the dominoes in motion, the first domino must be knocked over. Researchers now know that insulin resistance is a necessary catalyst that starts the domino effect.

Can this domino effect be avoided or stopped? Absolutely! To do this you need to make health style choices concerning your diet. It is important to have the knowledge of a few concepts of sugar biochemistry – the relationship between sucrose, glucose, fructose, insulin, insulin growth factor (IGF), and leptin.

There are three reasons that refined sugar is so dangerous.

  1. The speed in which refined sugar enters the bloodstream. This causes a vicious cycle of sugar highs followed by sugar lows. The sugar highs fuel cancer’s growth by allowing cancer cells to feast on glucose.
  2. The effect of elevated insulin levels in the bloodstream. Repeatedly overloading the bloodstream with sugar leads to insulin resistance – a condition where the body’s ability to respond to insulin is diminished. Insulin resistance is linked to the incidence and progression of several cancers.
  3. Fructose is the straw that breaks the camel’s back. There is a very strong link between excess fructose and obesity, heart disease, and cancer.

Lewis Cantley’s research team is working on developing drugs that will cut off the glucose supply to cancer cells and keep them from growing. Until there is a breakthrough, Cantley’s advice? Don’t eat sugar. And if you must, keep to a minimum. Cantley said: “I live my life that way. I rarely eat sugar.”

It is quite clear that if you want to avoid cancer, or are currently undergoing cancer treatment, you absolutely must avoid as much refined sugar and high-fructose corn syrup as possible.

What do you eat that contains high-fructose corn syrup?

    What about raw cane sugar or brown sugar?



      A rose by any other name is still a______!

      Brown sugar is simply refined white sugar that has had a portion of its original molasses mixed back in during the final stages of processing.

      Raw sugar is actually not “raw.” The main reason people believe raw cane sugar is healthier compared to regular sugar is because it is less processed and refined. Actually, raw sugar goes through half of the processing steps required to produce regular white sugar, which still makes it a processed food.

      The sweet taste comes from fructose not glucose. Even partially processed sugar sends excess fructose to the liver – more than it can handle, the excess is converted to fat. It just causes the liver to have to process more toxins (poisons).

      I hope this is helpful.


    So true. Thanks for the excellent information-



      Thanks for you comment. I noticed on your profile that you “like to provide hope” to those seeking a healthier life.” Perhaps you might like this: “Hope is being able to hear the music of the future. Faith is being able to dance to it.”
