<<Disclaimer: Verify this information before applying it to your situation.>> I'm not sure if this advice will be appropriate for your daughter who has a problem with constipation, hypoglycemia, gluten, and food allergies. I have gluten intolerance which is made worse by hypoglycemia (when I eat too much fruit or carbohydrate items) and food allergies (tomatoes and eggs mostly). But one thing I don't have is constipation. I attribute this to the amount of lettuce I eat everyday. At least two salads a day. BJ
