People who have been exposed to a seasonal “common cold” may experience less severe COVID-19 symptoms. While we’ve discussed this topic previously, a study from the Journal of Clinical Investigation reports the first clinical evidence of cross reactivity with the common cold and COVID. This is due to previous immune responses against the four endemic…
DetailsScientists are continuing to explore the role of furin proteases in the development of drugs to address COVID infections. This is a topic Dr. Fitzgerald has written on previously, including a peer-reviewed publication discussing dietary, lifestyle, and natural options to consider for lowering furin levels.
DetailsHigh-dose biotin appears to be ineffective and potentially harmful in the treatment of progressive multiple sclerosis (MS), contradicting an earlier study. A randomized trial from The Lancet of over 600 participants with MS found those who took 100 mg of biotin three times per day (10,000 times higher than the RDA) or placebo failed to…
DetailsDogs not only serve as playful and loving family companions, but now research suggests they also help keep kids’ immune systems healthy. A study found pregnant moms with a dog in the home had children with less immunoglobulin E (IgE) allergies. Adolescents who had prenatal exposure to dogs showed nearly a 30% decrease in IgE…
DetailsImmune cells in our gut appear to help protect the brain from infection. A fascinating study in mice suggests that immune cells in the gut are trained to recognize and respond to pathogens and then move to the brain’s surface to protect it. The lining of the gut is rich in immunoglobulin A (IgA), antibodies…
DetailsNew research adds to our existing knowledge and experience that some medications may inhibit weight loss, even when lifestyle interventions such as diet and exercise are prioritized. The Look AHEAD randomized study followed over 5000 middle-aged diabetic participants for 13.5 years and found overweight or obese participants taking obesogenic medications, or drugs that tend to…
DetailsSupplementing with omega-3 fats DHA + EPA, with a higher ratio of DHA, may increase physical power output and prolong the time before exhaustion (specifically before reaching the lactic acid threshold) according to a new study. Participants in a recent study of 50 amateur cyclists published in the Journal of the International Society of Sports…
DetailsCan including gluten early in an infant’s diet prevent celiac disease (CD)? New data supports this possibility. Analysis of the Enquiring About Tolerance (EAT) randomized, controlled trial published in JAMA Pediatrics this September reported that none of the 488 children in the early introduction group who consumed around 500 mg of gluten per day (equivalent…
DetailsEnvironmental toxins have been shown in several studies to be a potential trigger for immune dysfunction and autoimmunity. Now new data, from ex-military personnel, adds to that evidence base. In this recent study, published in Arthritis & Rheumatology, U.S. veterans exposed to military burn pits and waste disposal were found to harbor more antibody markers for rheumatoid…
DetailsDementia risk may be reduced by consuming dietary soy, at least in those who have the right kind of gut microbes to produce a compound called equol from its soy-derived precursors. Equol is a metabolite of the soy isoflavone daidzein that is produced only by specific gut bacteria. A recent study assessed serum levels of equol in…
DetailsA new study from Japan suggests people with type 2 diabetes who consume both green tea and coffee (quite a methylation adaptogen cocktail) have a lower risk of death. By a significant amount. Researchers studied nearly 5,000 patients over a five-year period and found that drinking either beverage alone helped reduce the risk of mortality (from any cause): Drinking…
DetailsLong COVID is now recognized as a post-viral syndrome of chronic debilitating symptoms that can last for months. Similar post-viral syndromes that have been observed follow other infections such as influenza, pneumonia, Epstein-Barr virus, and HIV. New data from a recent study by Kings College London of 4 million individuals in the United Kingdom indicates that: It’s relatively…
DetailsI am deeply impressed with the functional medicine community in taking on multiple, strong leadership roles around the pandemic.
DetailsChildren whose mothers had anxiety and depression during pregnancy may have an increased risk of developing asthma at 10 years of age, according to a new prospective cohort study of over 4000 children. Results showed a 46-91% increased risk of asthma and lower lung function in children whose mothers experienced stress or depression while pregnant. Paternal stress…
DetailsWhen is bread not actually bread? When it’s Subway bread, according to a ruling by the Irish Court.
