    A case report by Kurtovic et al. (2005) describes a man who had been experiencing diarrhea and abdominal pain for 27 years.  He was diagnosed with SIBO by duodenal aspirates registering 1012 CFU of bacteria/mL.  He was given antibiotics for four weeks, with no improvement in either symptoms or bacteria count.  Then he was given…

    A systematic review by Pan et al. (2019) concluded that people who consume alcohol are more likely to be diagnosed with GERD than those who don’t drink regularly, in a dose-dependent manner.  When looking at subgroups, they found that studies conducted in Asia resulted in a statistically significant relationship between alcohol consumption and GERD, while…

    Some studies (Ahmad et al., 2020; Serrano et al., 2021) have concluded that consumption pf normal amounts of artificial sweeteners such as aspartame, saccharin, or sucralose, does not impact the gastrointestinal microbiota.  However, Suez et al. (2014) found the correlation between non-caloric artificial sweetener intake and Enterbacteriaceae, Deltaproteobacteria, and Actinobacteria to be statistically significant, when…

    A study by Ghattargi et al. (2018) highlights the potential for strains from a single species to range from probiotic to pathogenic, with some being cultivated in traditional fermentation while others exhibit a neutrality that is neither probiotic nor pathogenic.  This study compared the genomes of ten different strains of Enterococcus faecium.  While these different…

    Hong et al. (2016) investigated the mechanisms behind how particulate matter, which contains chemicals such as polycyclic aromatic hydrocarbons (PAHs), causes rhinitis. This was an in vitro experiment, but they found that in cells exposed to particulate matter, reactive oxygen species were increased, while superoxide dismutase, catalase, and glutathioneperoxidase were decreased. When the cells were…

  • Glucuronidation and Enterohepatic Recirculation

    β-glucuronidase produced by the microbiome can deconjugate xenobiotics that have already undergone glucuronidation by phase II enzymes, causing them to undergo enterohepatic recirculation rather than being eliminated in the feces.   Elmassry et al. (2021) found that males have higher levels of intestinal β-glucuronidase than females, and infants have higher levels than their mothers.  Malik et…

    One group of clients for whom I would recommend diaphragmatic breathing are those who are interested in detoxification yet are also experiencing ongoing stress.  The IFM handout, Breathing Techniques to Soothe the Soul, gives a good description of the modality on one page, and suggests that five minutes of practice would be enough to achieve…

  • Sleep and Muscle Mass

    Daily rhythms of light and darkness have been a part of human evolution.  While some animals are more active nocturnally and humans tend to get exercise and food in the daylight hours, our evolutionary heritage may have led to shared similarities in how circadian genes orchestrate muscle cells’ response to the energy influx that comes…

  • Protein, Brassicas, and Dietary Fiber

    I found an interesting study where glutathione was found to decrease after participants spent three days on a lower protein diet than what they were used to, but it appeared to return to normal by day ten (Jackson et al., 2004).   Eating brassicas could help the estrogen metabolizing pathways to lead to less of…

  • Polyphenols for Intestinal Permeability

    Del Bo’ et al. (2021) conducted a randomized controlled trial to see if a diet emphasizing polyphenols would be able to help address intestinal permeability in older people.  They found that beneficial bacteria for fiber fermentation and butyrate were increased, and blood pressure was decreased.  Those who started out with greater impairment of the tight…
