In the side print it states:

products have some carbohydrate--they may be one of your options for a few grams .

Meaning read the label. If you select an orange soda that has 40 grams of carbohydrates and your limit is 20 a day......that isn't the one he is talking about.

I am sure he is talking about either a natural orange type drink with soda water, or maybe an orange essence type. Not sure. After being on Atkin's for almost a year I prefer water over most anything else to drink.
