Gut Health, Antibiotics and Swimming with Dr. Grace Liu – FAM #053

Dr Anh | Food as Medicine and Using Nutrition to Reverse Diabetes, High Blood Pressure, Cholesterol & Other Chronic Illnesses

Grace shares the following about gut health:

  • Gut health is important for many reasons, but one reason is that 80% of the immune system is in the gut. Operating without proper gut health is like operating with only half of your brain!
  • Grace uses a “tree” picture to illustrate each person’s microbiome, showing the branches of the different bacteria found in the gut.
  • Many problems and health disorders are caused when the needed varieties of bacteria aren’t present. One problem is the presence of too many antibiotics in our society!
  • If you aren’t feeling well, you probably need to replenish the needed bacteria. Grace discusses the inexpensive tests that can be done to assess the composition of the gut.
  • Dysbiosis or SIBO (small intestine bacterial overgrowth) is common in the upper gut; sometimes a low carb diet can help.
  • Grace explains the process of “weeding” as it applies to monitoring your gut flora.

    Hi Dr Grace

    I was chatting with you in the comments section of one of your earlier blog posts about ankylosing spondylitis and the klebsiella link, and you suggested that klebsiella may not be the culprit at all.

    Anyway, I’ve since had the Genova stool test carried out and indeed, klebsiella didn’t show up, but citrobacter and enterobacter did. I also did the SIBO breath test and tested positive (methane type).

    I’ve been trying to treat this with oregano oil tablets, allicin, berberine and a product called Whole GI Wellness for the last 8 weeks and whilst this may have gotten the SIBO under control (although I cant be sure as I haven’t retested yet, but if it’s of any significance – I have never had any GI symptoms anyway) but my pain levels haven’t improved.

    I’ve been gluten free for around 2 years now which has improved things somewhat, but there are definitely other things in my diet still causing inflammation. With this in mind, I therefore ordered the Cyrex Array 4 Gluten Cross Reactivity test and received the results of this yesterday. Almost everything was within the normal range which, I found very surprising as I suspected that either dairy, rice or coffee was a problem, but these were all fine according to this test.

    The only thing I was out of range for was aramanth, and then equivocal for whey protein, buckwheat, sorghum, tapioca and teff – none of which I ever eat anyway…

    As I you can imagine, I’m now in a bit of a quandry about where I go from here. The only thing I can see as a logical next step is adopting the full Paleo AIP however, I’m relautant to do this as I’m already underweight.

    Based on the above, do you feel that there are any other avenues we could potentially explore if I were to book a consultation with yourself?

      Honestly William I have no idea why people do everything on the internet and waste there precious resources and time. Consider an expert opinion and integrative medicine consult. Would you take your Tesla to a Honda dealer and use Honda parts on it? Or worse fail to hire the wrong diagnostics then try to DIY it?
