Wheat causes wide swings in moods. ( Dr. Williams new best seller called Wheat Belly
is enlightening about these things.) Wheat also causes cravings, just as sugar does
and is addictive, causing you to seek more and more every two or three hours.

Wheat will give me a headache, too, along with rye bread, especially.
(Dr. Williams says that it causes migraines, as well--at least one cause of it.)
