Sugar is poison
Because it's high calories but empty calories, meaning no nutritional value. No protein. No vitamins. No minerals. But your body is designed to process it by sending out insulin to manage it. Your cells survive by feeding on sugar molecules produced by digestion.
The sugar is the car. The cell is the garage. The insulin is the garage door opener. Diabetes is when you don't have enough garage door openers to feed your cells so they are screaming for food. People crave more sugar because they are starving. The sugar is left to circulate around in your blood stream causing high blood glucose. That in turn, damages organs, the little capillaries in your eyes, and your fingers and toes. Then you get neuropathy from nerve damage. Retinopathy happens to your eyes and you go blind.
The crappy thing they won't tell you about HFCS is your body doesn't recognize this man made poison as sugar, so it won't produce insulin as a response to it. So then it floats around in your blood stream doing damage until it goes true your liver and turns to stomach fat. Then you have to exercise to burn it off.
My belief is that is the crux of this new diagnosis of "insulin resistant" diabeties. It actually produces a disease because it's that bad for you.
All sugar is NOT alike. And beware they no longer must label HFCS as HFCS, it can now just be called fructose which suggests its fruit sugar. It's not. It's corn squeezings. Buyer beware.
