Hi Peggy, unfortunately one of the shortcomings of this wonderful site is that there are limitations to the foods in the database at the present time (though this concern has been raised and the administrators may be working on it).
It is, however, possible to enter any food, including Atkins products, as a custom food. Go to the column on the left, click on Create a Custom Food, and enter in the nutrition info from the product packaging. Then it will be in your list of custom foods to click on whenever you need to put it in your food log in the future.
