Geezer has been surprised, recently, by the increasing number of friends who report a sensitivity to gluten. If it’s not celiac disease, it is sufficiently unpleasant that these people make an effort to steer clear of wheat, a grain that, it turns out, is much harder to avoid than it should be. At the same time, Geezer and the rest of the U.S. population have another good reason to look for grains other than wheat: wheat gets tired. So it’s encouraging to read in Outside magazine about grains that are packed with fiber, minerals and vitamins and are less boring than wheat. Note to celiac afflicted readers: barley and oats, both on the list, do contain some gluten.And the winners are: amaranth, quinoa, barley, and oats.
