Q: My 15-year-old daughter seems to be run down all the time. She lives on candy and sweets. I wonder if she could have sugar intoxication.
A: We're not sure what you mean by sugar intoxication. Ingestion of large amounts of refined sugars (found in candies and other manufactured sweets but not in fresh fruits) may be bad for your teeth, and they should be consumed sparingly by individuals with diabetes.
But in people without diabetes, eating sweets (even in "large amounts") does not lead to the symptoms you describe. We do believe, however, that consumption of refined sugars should be limited since these products usually contain large amounts of fat (chocolate is an excellent example) but very few essential nutrients.
