Many of the foods you listed contain glucose in one form or another. For example, carrots, courgettes, orange juice and bananas contain 1, 1, 2.3 and 5 grams of glucose per 100 grams as well as other sugars such as sucrose which is 50% glucose and 50% fructose.
Glucose is the most fundamental form of energy the body consumes. As Heather says "For glucose concerns, your body eventually breaks down all carbohydrates (simple and complex, and no matter what the source or how much/which type of fiber they contain) into glucose, as this is the only fuel the brain can use."
The only way glucose sensitivity can likely occur would be through its effect on blood sugar levels. This why a Google search does not reveal anything about glucose sensitivity but only blood glucose levels.
