Sugar does not make you hyper, what could be making people hyper is the chemicals or additives in the food! Sugar in it's natural state may give you a bit more energy but in no way should it make you hyper, if it does, you may have trouble processing sugars and need to go get tested.
Too much sugar is bad for health, but how much is too much? The accepted guideline is that added sugars should not make up more than 10 percent of your total energy intake for the day, although, many nutritionists will recommend even less than this. How much is 10 percent? Well, in a 2000-calorie-a-day diet, 10 percent would be equal to about 50 grams, or 10 teaspoons of sugar. Unfortunately, most Americans consume 30 to 40 teaspoons or more of refined sugar per day. Most of this sugar comes from food products to which sugar has been added, such as soda, candy and baked goods. A can of soda alone can contain around 10 teaspoons of added sugar!
