Check out this site: http://www.vegetarianteen.com/articles/robertcheekeprotein.shtml Scroll down to the protein content section of the page, and you'll see that the content in seitan is variable (15-31g/3oz serving). The pro content in seitain (gluten) varies depending on how it's made- you just n3eed to check the label, or, if you make your own, use a very high-gluten whole wheat flour, and throw in pur gluten to enhance the product. (Yes, it is entirely possible to make your own seitan, and I can tell you- it's great for the forearms- similar to kneading bread dough.) Anyway, calorie for calorie, gluten generally contains the same pro content as beef. BTW, "complete" proteins are very, very easy to get even for a vegan. Soy is complete, for example. Also, I'm afraid that the issue of protein completeness is a hangover (literarlly) from the Lappe books (Diet for a Small Planet, e.g.). We now know that you don't have to complete proteins at every meal (although grains and beans are a very nice combination anyway). Like Ruthenian says, it's easy to get protein at 1g/lb levles (and, alas, calories too) on vegetarian or vegan diets. Like everyone else, we have to be careful what we eat.
