Sugar is digested by enzymes in the small intestines. Insulin is released to regulate blood glucose.
That is not the main thrust of my point. The point is insulin does not know the difference between cane sugar intake or HFCS intake.
And even more important point is the HFCS drinks can be sold in bigger quantities because it is cheaper to manufacture them. Moderation is the key to good health. Stick to smaller quantities of sugar, and include a balanced exercise program in your routine, and you will have a better chance of fighting heart disease, diabetes and even cancer.
