Have a suspicion you might have celiac, or perhaps gluten sensitivity? You need a trusted source for information.

One valuable resource is the new "Mayo Clinic Going Gluten Free: Essential Guide to Managing Celiac Disease and Related Conditions," by Dr. Joseph A. Murray, who has been treating patients with celiac since the 1970s, before most American doctors knew it existed. The Mayo now has one of the nation's largest celiac labs, with clinics in Scottsdale, Ariz., and Jacksonville, Fla., as well as Rochester.

Murray has put together an extensive and easy-to-understand guide, starting with up-to-date science on reasons to avoid gluten, and covering everything from label reading and dining out to dealing with flare-ups and helping a child navigate life without gluten. The book offers a nutritionally sound, easy-to-follow plan with the shared expertise of the Mayo Clinic team.
