Hi Jan,
Thankyou for fodmaps info. I suffer IBS symptoms consisting of bloating,flatulence and abdominal pain. I have found foods such as cauliflower,raw cabbage,lentils,white beans,bollotti beans,chick peas and thermophilis in yoghurt cause synptoms. I take nexium,citracal,vitamin D,1/2 teas. psyllium husk and quick fibre plus daily. I have had surgery for a hiatus hernia but still require nexium. I have low bone density hence the citrical and vitamin D. I was diagnosed with diviticulitis 16 years ago and require psy.husk and QFP to help with regularity. I always have IBS symptoms after taking antibiotics as well as at other times.A blood test for celiac has proved negative. I am 65, do we become intolerant to certain foods etc. as we age? Should I try the LOW FODMAPS diet?

    foods you’ve listed are high in galactans. QPF contains FOS (fructooligosacharides) that may have the same irritant effect, like galactans. It’s possible (but not necessary) that also fructans in wheat and onions irritate you. Psyllium husk is high in soluble fiber, which can yield a lot of gas when broken down by normal intestinal bacteria. Psyllium husk is meant to make stool soft, but you can achieve this with other foods, like whole grain bread and green salads, which contains less soluble and more insoluble fiber.

    Helicobacter pylori bacteria in the stomach is one possible cause of excessive gastric acid secretion. Diagnosis is with blood or breath test, treatment is with 1 week antibiotic course.

    Ideally all nutrients should be obtained by food, not supplements. I mean, I can hardly recommend you any diet trial, if I don’t know does gas come from psyllium husk or eventual other source of soluble fiber in your supplements.

    Small intestinal bacterial overgrowth (SIBO) is a common “side disorder” of certain food intolerances. Diagnosis is with breath test, treatment with antibiotics.

    Statistically, with age, there is more lactose intolerance and probably fructose malabsorption, but less IBS.

    You can try low-FODMAP diet, which is basically a combination of lactose-free + low-fructose diet. Here is a list of non/problematic foods in fructose malabsorption:

    One possible approach could be:

    1. Reducing amount of psyllium husk and QFP and partly substituting them with cereals lower in soluble fiber, like corn, whole grain bread or green salads (and see if there is less bloating/gas. If no difference…
    2. Trying a low-FODMAP diet (or only a low-fructose diet, if you think you can tolerate milk). If no difference…
    3. Asking a gastroenterologist about tests for H. pylori or SIBO.
