Penny, I am so surprised with your background that you are saying sugar & behavior are not connected. I can tell you that my 12 yr. old adopted Grandson can have a donut or candy and within 30 min. is “motor mouth”, jumping around, pesting, etc. Not at all his common behavior. I also watch any processed foods and he knows how to read labels and count carbs. Others have witnessed this behavior and are too aware of his behavior on sweets. If he had cookies for lunch his teacher would be calling me about disrupting the class.
