Fats and protein also slow the spike of glucose from eating sugary foods. This is referred to as the glycemic index. Sniker bars and ice cream, for example, are fairly low on the glycemic index because they contain fat and/or protein, even though they don't contain much fiber.

However, I'm not aware of scientific evidence that sugar is bad for people with normal metabolisms. Their glucose won't spike because it's well regulated by the body (insulin). If you have risk factors for diabetes or metabolic syndrome, you should be more cautious about intake of sugar and other food with high glycemic index. For Type 2 diabetics, the American Diabetes Association has recommended eating sweets only as an occasional treat, and eating them at the end of a meal that contains protein and fat to slow absorption of the sugar. This advice applies for fruits as well as processed sweets, except that fruit should be eaten on a daily basis.
