“Conclusions Lactobacillus reuteri has demonstrated a plethora of unique biological effects across a wide range of clinical and non-clinical research that seemingly converge on a few fundamental mechanisms, including strengthening the gut barrier and immune system, improving metabolism, and protecting infants from digestive diseases, among others.”

“Of particular relevance in viral disease is the movement of zinc, an essential nutrient that inhibits the action of RNA-dependent RNA polymerase — the enzyme critical for the reproduction of RNA viruses such as SARS-CoV-2, the virus responsible for COVID-19.”

“One study in particular identified zinc as an inhibitor of RNA-dependent RNA polymerase – an enzyme that drives the replication of RNA from an RNA template – in the virus SARS-CoV-1. Zinc is a positively charged ion and cannot enter cells without a transporter.”

“SARS-CoV-2 attempts to evade the immune system by suppressing the interferon response. Dr. Roger Seheult shares the findings of two recent studies in which researchers identified a connection between an impaired interferon response and severe COVID-19 disease.”

“Measures such as refreshing and recirculating cabin air through specialized filters contribute to low transmission on airplanes. In this clip, Dr. Roger Seheult explains that well-ventilated spaces are a factor in dampening the spread of the SARS-CoV-2 virus.”

“While infection with the SARS-CoV-2 virus shares symptoms with the common cold and influenza such as sore throat, cough, and runny nose, there are critical differences in the severity and duration of COVID-19 illness.”

“The immunity conferred in breast milk has relevance for COVID-19. A small, prospective cohort study investigated whether antibodies to SARS-CoV-2, the virus that causes COVID-19, are present in the breast milk of women vaccinated against the disease.”

“With such an important set of responsibilities, it is unsurprising that a decline in T cell-mediated immunity contributes to debilitating age-related illnesses: Reduced infectious immunity – Immunosenescence, a cellular process integral to thymic involution, is associated with reduced immunity to influenza and other respiratory infections and less effective response to influenza vaccination.”

“Authors of a 2021 study recruited 50 participants (between ages 18 and 75 years) who were not consuming dietary supplements or large quantities of olive oil (greater than one tablespoon per day).”

“DAMPs such as HMG-1 bind to TLR4 and receptors for advanced glycation end products (RAGE) on cells at the blood-brain barrier to induce an immune response that initially inhibits the deposition of amyloid-beta, a key feature of Alzheimer's disease progression.”
