Fructose causes seven times as much cell damage as does glucose, because it binds to cellular proteins seven times faster; and it releases 100 times the number of oxygen radicals (such as hydrogen peroxide, which kills everything in sight).

This takes into account how much of a given food one must eat to obtain 50 grams of carbohydrate. The perfect example is carrots. Carrots have a high glycaemic index – if you consume 50 grams of carbohydrate in carrots, your blood sugar will rise pretty high. But you would have to eat 1.3lbs – 600 grams – of carrots to get 50 grams of carbohydrate
