<<Disclaimer: Verify this information before applying it to your situation.>> I am new to the list and need advice. My husband and two sons are intolerant of gluten foods. My youngest has problems with many other foods and I have a difficult time putting any diversity into his diet. Just to keep this short I'll focus on just a few questions- Can anyone tell me anything about "disaccharide intolerance?" What are the symptoms? What foods contain larger quantities of disaccharides? How is it diagnosed? (Our family doctor's nurse said that this is usually brought on by cd or other pre-existing problems) My youngest son (2 yrs. old) swells up and belches (and sometimes even vomits) a strong yeast smell, whenever he eats certain foods which he is intolerant of. Does anyone recognize this. Thanks much, Karen Columbia,MO
