(The Best Years in Life) The orthodox theory of cancer is that it results from the mutations in the genes of normal cells which, in turn, are caused by various factors including environmental carcinogens. The problem with this theory is that there is lots of research showing that gene mutation is neither necessary nor sufficient to bring about cancer. However, Nobel Prize winner Otto Warburg already showed as early as 1924 that in cancer cells the production of Adenosine Triphosphate (ATP) better known as cellular energy is disrupted. He incorrectly concluded that it was due to a STRUCTURAL defect in cellular mitochondria, the main source of ATP production. It took another 60 years before it was shown that cancer was due to a FUNCTIONAL defect in the mitochondria. This change in the function of the mitochondria is most likely due to the depletion of the main antioxidant in the body – glutathione – as a result of lifestyle situations and toxins. Read More.
