SUGAR FUELS CANCER

  • After leukemia (and during) people kept telling Vinnie he needed to do certain things. (3:00)
    • Eat macro-diet and micro-diet, juice everything, have wheatgrass, etc. or he would die.
  • He went to his hematologist and asked how much of it was the truth.
    • His incredibly intelligent hematologist simply said, “Stay away from sugar!”
      • Everything is pointing toward sugar as one of the things that cancer loves.
  • Sugar does not cause cancer; cells that make tumors feed on sugar. (4:40)
    • Sugar is a prime fuel, but not the only fuel.
    • Our red blood cells are constantly making a little lactate.
    • Tumor cells have defective mitochondria so they make lots of lactate.
  • Dr. Seyfried explains the mechanisms behind the process and why it’s so important to understand.

WHAT CAUSES CANCER?

  • Cancer can be caused by a variety of things. (8:20)
    • Some examples are radiation exposure, chemicals in the environment, chronic inflammation, and age.
    • Mutations in genomes that we inherit can be involved. (10:35)
      • People can be predisposed to cancers.
      • Genomes are your set of genes and differences and mutations in them.
    • However, there is a misunderstanding about cancer; the industry has believed that cancer is genetic because tumors have mutations. (11:50)
      • This has caused a lot of misdirection in research and treatment.
  • Dr. Seyfried explains even more of the science of how cancer cells work; cancer is a metabolic disease. (23:30)
    • They also discuss the benefits of ketones and the ketogenic diet.
    • It is highly important to understand the difference between ketosis and ketoacidosis–they are very different things.
  • They discuss therapeutic ketones and whether or not they can help certain brain processing issues like autism. (55:00)
  • You can read more about Dr. Seyfried on Boston College’s website.- https://www.bc.edu/bc-web/schools/mcas/departments/biology/people/faculty-directory/thomas-seyfried.html
  • Dr. Seyfried recommends the book Tripping Over the Truth, by Travis Christofferson.
