The Center for Science in the Public Interest (CSPI), a pro-consumer lobbying group, publishes some of the most useful consumer materials on the subject of food and nutrition. Ask them for a sample copy of their newsletter, Nutrition Action, and their catalog of books and computer programs. My own personal favorite is their Nutrition Scoreboard ($3.95), a kitchen wall poster which lists “health scores” for dozens of different kinds of foods. This is the expert to consult when making out your shopping list. If you are committed to healthy eating, you should consider becoming a member of CSPI.
