Check out "The False Fat Diet" by Elson Haas - it's a real eye opener for anyone who struggles with bloating. Here's an excerpt from the Amazon review:
If you know you swell up after bee stings, you avoid bees. If you know a close encounter with poison ivy will leave you itching and scratching for a week, you keep your eyes open for three-leafed plants. But, according to The False Fat Diet, many of us spend our entire lives eating foods that "don't agree with us," and as a result carry around extra pounds, put up with allergies, and go through life looking older and feeling less energetic than we should. Of course, the hook here is weight loss. If you eliminate the foods that make you gassy and bloated, you can probably drop pounds instantly--up to 10 pounds of "false fat" in a week, Elson Haas says--and then keep dropping weight in subsequent weeks and months, the real fat, all without feeling hungry or deprived.
