I checked the USDA nutrition site and it agrees with the info in the Zone book. 1/4 cup (43 grams) of boiled soybeans contains a little over 7 grams of protein. Here's the address to that info:http://www.nal.usda.gov/fnic/foodco...ut_edit.pl
Yes, I go by the nutritional content of the food itself for foods not listed in the Zone food block list.
You can be confident relying on the food block list.
