Study proves sugar is responsible for remarkable rate of disease
From a nutritional standpoint, your body does not need refined sugar. Although you need glucose, your body manufactures the glucose it needs in your liver through a process called gluconeogenesis. If you never ate another morsel of candy, sugar or starch again, you would live quite comfortably and likely in far better health.
Sugar Feeds the Growth of Cancer Cells
Recent research reported in this short news video demonstrates that the amount of sugar you eat each day should be an important consideration in your nutritional plan. In 1926, German biochemist Otto Warburg observed cancer cells fermented glucose to lactic acid, even in the presence of oxygen (known as the Warburg effect), and theorized it might be the fundamental cause of cancer.
This led to the idea that tumor growth could be disturbed by cutting off the energy supply, namely sugar.
For decades, scientists and researchers dismissed the idea, and the sugar industry backed them up. Warburg received the Nobel Prize in Physiology or Medicine in 1931 for his work in cellular respiration and energy production.
His life’s mission was to find a cure for cancer, but his findings were largely ignored by the conventional medical community as they were considered simplistic and didn’t fit the genetic model of disease that was widely accepted.
Recent research from Belgium4 shows there is indeed a strong link between glucose overstimulation and mutated proteins often found inside human tumor cells, which make the cells grow faster.
5 The study began in 2008, triggered by the researchers’ desire to gain a greater understanding of the Warburg effect.
The rapid breakdown of glucose in tumor cells is not seen in healthy cells, making glucose the primary energy source for cancer. Researcher Johan Thevelein, Ph.D., a molecular biologist from LU Leuven in Belgium, commented on the results of the study in a press release, saying:6
“Our research reveals how the hyperactive sugar consumption of cancerous cells leads to a vicious cycle of continued stimulation of cancer development and growth. Thus, it is able to explain the correlation between the strength of the Warburg effect and tumor aggressiveness.
This link between sugar and cancer has sweeping consequences.
Our results provide a foundation for future research in this domain, which can now be performed with a much more precise and relevant focus.”
Cell Mutation Not Limited to Sugar Consumption
They’re quick to point out that while they believe the presence of added sugar in your diet may increase the aggressive growth of cancer cells, their research does not prove it triggers the original mutation.
7 That said, previous research has shown that the genetic mutations found in cancer cells are actually a downstream effect caused by mitochondrial dysfunction, not the original cause, and excessive sugar consumption is one of the things that triggers mitochondrial dysfunction. I’ll discuss this more in a section below.
Granted, there are thousands of manufactured chemicals in your home, car and workplace that may cause or contribute to cell mutations. Air pollution, personal care products, plastics and chemical treatments often contain chemicals with carcinogenic properties, and such exposures also play a role.
The mutation of a cell, fed by your daily sugar habit, may grow into cancer. Cell mutation from sugar consumption occurs after mitochondrial damage. However, sugar also provides nutrition to cells mutated by contaminant exposure, and is required for these mutated cells to grow and multiply. As such, your sugar intake becomes an important factor, and one that you have a great deal of control over.
Normally, energy is drawn from glucose through a process of oxidation that requires the presence of oxygen.8 But, cancer cells use a process of fermentation, even when oxygen is present, to create energy. The process, called glycolysis, extracts less energy during the process, but requires less energy and fewer steps to get energy from glucose.
