The Sugar and Cancer Connection

Sugar is bad for your skin, promotes premature aging, and causes hard–to–lose weight. But there's something esle you need to know about sugar: it feeds and promotes cancer. The sugar and cancer connection is not well know, and it hasn't been publicized in mainstream sources. Yet, the connection is backed by solid research, including the following:

  • Pancreatic cancer cells use the sugar fructose to help tumors grow more quickly. This was discovered by researchers at UCLA’s Jonsson Comprehensive Cancer Center. They concluded that anyone wishing to cut their cancer risk should start by reducing the amount of sugar they eat.

  • Depriving cancer cells of glucose leads to cancer cell death. The research was conducted by Thomas Graeber (a professor of molecular and medical pharmacology) and colleagues, and then published in June 26, 2012 in the journal Molecular Systems Biology.

  • Sugar feeds tumors. Research done by the Huntsman Cancer Institute, and published in the journal Proceedings of the National Academy of Sciences, states “. . tumor cells use a lot more glucose than normal cells. Our research helps show how this process takes place, and how it might be stopped to control tumor growth.”

  • Women in their teens who ate high–glycemic foods that increased their blood glucose levels had a higher incidence of breast cancer later in life. The study was done by Harvard Medical School in 2004.

  • Cancers are so sensitive to the sugar supply that cutting that supply will suppress cancer. This was the conclusion of a comprehensive review of the literature on carbohydrates and their direct and indirect effect on cancer cells. It was published in the journal Nutrition and Metabolism in October of 2011.

The average American consumes 77 pounds of added sugar per year!

Why do we crave It?

Sugar has some of the same characteristics as a toxic drug. When sugar hits our bloodstream it stimulates the same pleasure centers of the brain that respond to heroin and cocaine. Eating just a small amount creates cravings for more, and quitting suddenly causes withdrawal symptoms, like headaches, mood swings, cravings and fatigue.

How to start eliminating sugar from your diet.

Sugar can be a hard habit to quit. Precisely how hard depends on just how much sugar a person is consuming daily. As a start, read food labels and notice the amount of added sugar there is in everyday products. You'll be astounded at how much you're actually consuming. Then, start eliminating these processed foods from your diet.

Replace all sugary snacks with whole fruits, and use low-glycemic, natural sweeteners, like Xylitol. We want natural sweeteners with a low GI (Glycemic Index), because excess sugar in the blood spikes insulin levels. Insulin is pro–inflammatory and pro–cancer and can directly promote the growth of tumor cells.

It's common for people who are transitioning to a vegetarian diet to eat more simple carbohydrates, like pasta and bread, which are high GI foods. A good way to avoid this issue is to eat a well-balanced diet that contains a high quality, vegetarian protein at each meal.
