Re: Lettuce/raw greens intolerance?
Welcome to healthboards. Several books I've read say that people that have IBS are also have intolerances to one or more foods. So, I guess this is normal and not unusual. You know alot of green leafy veggies are treated with nitrates to preserve their freshness and crispness. And, many people are very sensitive to these additives and have to go to unusual measures to wash these veggies to get rid of the residue. Particular those packaged and ready to serve types as well as salad bars.
It would be interesting if you bought some alfalfa or barley grass tablets from a health food store and see if you are really intolerant the content in these???
I hope you find an answer to your problem!!
