Type 2 diabetes occurs when cells become resistant to the signal from insulin to receive and use glucose as fuel. Oxygen is used to break down glucose and fats, but in the case of glucose, 28% more oxygen is needed to create an equal amount of energy. Using oxygen requires anti oxidants to clean up afterwards. Anti oxidants such as glutathione are present within the cell, (within the mitochondria where metabolism occurrs) so this is not a problem. When glutathione is inadequate to clean up left over oxygen particles, healthy tissue gets damaged. This damage is what causes the cells to ignore the insulin signal and become “insulin resistant”. We are able to tolerate carbohydtrates to the degree that we can clean up the “after-burn”. Diabetes is caused by anti oxidant depletion, making carbohydrates a sub optimal fuel source. It looks like Polyunsaturated fats are the root cause the oxidatative stress that is robbing all our glutathione from where it was needed. If this sounds interesting, I write about this and other biological mechanisms on my page. Thank you for your article, upvoted!
