High refined sugar intake has always had a strong correlation to tumor development in cancer patients, but now there is evidence suggests that a high sugar diet can actually cause cancer.
According to Dr. Murray Susser, cancer cells consume sugar about 19x faster than healthy cells. The Positron Emission Tomography is one of the most accurate tools for measuring cancer growth.
The 1931 Nobel laureate in medicine, German Otto Warburg developed a hypothesis that cancer cells have a different energy metabolism compared to healthy cells. Malignant tumors, according to Warburg, exhibit increased glycolysis in contrast to healthy human cells.
How sugar produces cancer cells
The 2013-2014 Journal of Clinic Investigation released the results of an in vitro study that analyzed the results of increased sugar uptake and oncogenesis (cancer creation). The results demonstrated that increased glucose uptake had a direct and positive correlation to the early phases of cancer cell production.
One of the crucial mechanisms through which cancer is promoted through sugar is through mitochondrial dysfunction. Sugar burns very differently than fat does, which generates free radicals. When free radicals damage the mitochondria of the cell, the nuclear DNA, and cell membrane are also affected, leading to protein impairment.
Moreover, obesity and chronic overeating have had a positive correlation and causation to the growth and development of cancer cells. According to the Canadian Cancer Society, being obese can cause changes in hormone levels, such as sex hormones or insulin, which increase the risk of developing breast, colon or uterine cancer.
The study takes into account the difference between refined sugar and naturally occurring sugars. Refined sugars include table sugar and high fructose corn syrup that are absorbed by the body when consuming processed foods, sodas, and baked desserts namely added sugar. Naturally occurring sugars in fruits are deemed less harmful, regardless of their glycemic index.
Sugar from organic produce may not contribute to cancer cell growth in the same way refined sugars do because human cells absorb left-spinning molecules, which occur in fruits and vegetables, while cancer cells can only absorb right spinning particles, which come from refined sugar.
