they are on the Zone Blocks Guide that you can download at
http://www.zonediet.com/tools/zone-classic . Lentils are favorable carbs (1/4 cup = 1 block). Lowfat/nonfat milk is listed as favorable (1 block P, 1 block C). Nonfat cheese (1 oz = 1 P block) & cottage cheese (1/4 cup = 1 P block) are favorable.
As with all food, you have to see how it effects you. I take a lot of dairy and it works well for me. The lentils are probably best in moderation (1/4 cup per meal).
