So in light of Yesterday's paper on Gut Microbiome alterations in CFS ( https://eurekalert.org/pub_releases/2017-04/cums-cfs042117.php ), I am reassessing my Dietary options to possibly tackle potential Commensal/inflammatory/Pathogenic bacteria... Since Jan 2016 when I first started experiencing Fibro/arthritis type symptoms, I have been following an anti-inflammatory, elimination diet probably most akin to the Bulletproof diet (Green - Roadmap). Then over the course of the last year I have gradually reintroduced various things or experimented to see what I can tolerate, but Gluten/Sugar/Processed food/Alcohol are definite no-no's, Dairy I am on the fence and I have reduced Meat consumption considerably. I have cycled between strict Ketogenic, Relaxed LCHF, Strict Fruit/Veg diet (Gerson/Medical Medium) to see what works best for me. I think I do pretty well when having a Bulletproof coffee in the morning which throws you into ketosis and clears brain fog, adds slight energy increase and then Paleo, LCHF for the rest of the day. I would not consider changing from this really. HOWEVER after a quick bit of reading on the bacteria identified in Yesterdays paper and an annalysis of the three stool tests I have had, it would appear that this diet is actually supporting these imbalances. See here: https://www.ncbi.nlm.nih.gov/pubmed/24336217 ''The animal-based diet increased the abundance of bile-tolerant microorganisms (Alistipes, Bilophila and Bacteroides) and decreased the levels of Firmicutes that metabolize dietary plant polysaccharides (Roseburia, Eubacterium rectale and Ruminococcus bromii).'' Alistipes seems to be the main culprit, so does a High-Fat diet support it's proliferation? Any thoughts?
