Try nuts, peanut butter, almond butter, whole fruit (eaten with meals or with whole grain bread and cheese), Quaker Breakfast Cookies (Oatmeal w/choclate chips or raisins
in the breakfast aisle),
Quaker Simply Harvest
Instant Multigrain Hot Cereal (several flavors, I love the vanilla, almond and honey). Enterex Glucose Control nutrition drinks are more costly, but are good and have decent numbers on the label. Kind brand of all natural bars are more expensive than some, but are very good.
