For you to experience any negative effects from fructose, you'd have to consume around 50-75 grams in a sitting. That's equivalent to eating five to seven apples, one after another. You'd have to eat three or four of these "servings" a day, for a grand total of 15-28 pieces of fruit! As they teach us to say in college...well, duh! If you eat too much of a sugar—or anything, for that matter—you'll get fat.
