Fadi did you know that testes can also use fructose.
And did you know so can womens breats? But only! If they have canceorus cells in them.
Did you also know that if you look at a sucrose consumption graph in america it also rises and falls exactly the same as deaths from prostate cancer.
As for table sugar it is refined. Fruit has natural things that aid its high fructose levels ie Chromium and other things. When you refine things you stirp everything good away and leave the bad
It is true that we need a small amount of fructose to kick start our whole glucose process. But that only need be a serving of fruit not the amount people consume today.
I read this book i found it interesting.
As for table sugar after training i personally stick with straight glucose. I try to avoid fructose and sucrose unless it is in fruit.
