Dr. William Davis has an extremely hard sell with his book's thesis that wheat - not just gluten - is bad for us. In fact, he says, as the single largest contributor to the obesity epidemic, it may be killing us. Regardless of whether you buy the argument, "Wheat Belly" is well worth reading, if only to examine Davis' provocative expose of "the harmful effects of what is actually a product of genetic tinkering and agribusiness being sold to the American public as 'wheat.'" Yes, the "wheat" we eat today is nowhere near the wheat we boomers ate as little kids. It is four times more fattening, addicting and sickening than the Wonder Bread of old. The argument was compelling enough to make me give up wheat altogether for the past three days and, I have to admit, I feel really good. Thank goodness I'm no longer working in an office with crazy Christmas cookie-baking colleagues. Can I make it through next weekend's holiday parties? That remains to be seen.
