I guess that means all the sage advice to cut back on sugar to fight cancer is misguided.
To an extent. Again it goes back to a balance. It would be about impossible to eliminate sugars from the diet entirely. Even steak is going to contain sugars. And even if we could the body would generate its own glucose.
Keep in mind that the primary fuel for cells is glucose. So why don't people stop functioning when they go on water fasts for weeks on end? Their body generates glucose from other sources such as glycogen and fats to keep them going.
But people should not overdo it either spiking their blood sugar. What I was getting to was consuming sugars in moderation is fine, especially when consumed with fibers to slow absorption. This will increase the chances that most of the glucose will be utilized by healthy cells, such as muscle, instead of cancer cells.
