Serving low GI foods may help, however the total carbohydrate and the consistent amount of carbohydrate at meals from day to day may also be important. If your daughter likes the foods you serve, things should be just fine; however, sometimes it is important to have some sweets just to make life more normal.
Sometimes when sweets are only used when blood sugars are low, children decide they must get low to have a favorite food or sweet. Withholding foods also can create a magnified desire to attain them and can create dishonesty and guilt when high GI foods are eaten.
Food is not the only issue when considering blood sugar levels. Growth, stress and activity also affect blood sugars, so don’t forget to look at the whole picture. I believe that there is a lot of truth that lower GI foods probably extend the honeymoon period, however having a more normal eating pattern may have a positive psychological effect.
