The Shocking New Truth About CANCER! (Nobody Shares This) | Dr. Thomas Seyfried - YouTube – Very interesting new (relatively new, last ~20 years) research on the causes of Cancer, preventative measures and treatment. Also highlights that Cancer is not a genetic disorder, but a metabolic disease caused by environmental and dietary factors. Dr. Thomas Seyfried is cited in ~200 peer-reviewed papers, and has several books on the subject.
Sadly (however), since the research is relatively new, is only cited on Wikipedia: Caner a handful of times and there is only one reference (so far) or mention of “refined carbohydrates” under the “Dietary” section:
Dietary recommendations for cancer prevention typically include an emphasis on vegetables, fruit, whole grains and fish and an avoidance of processed and red meat (beef, pork, lamb), animal fats, pickled foods and refined carbohydrates.[15][129]
