Iso-osmo-resistivity could explain mechanisms of digestion and absorption

Title : Iso-osmo-resistivity could explain mechanisms of digestion and absorption

Abstract:

Research into suitable meals for epigastric impedance found that lipid meals like ones containing double cream are highly resistant to electricity while proteins are conductive and carbohydrates are broadly neutral. The finding provoked the question: “Is this the basis by which our digestion selects the appropriate enzyme and ‘knows’ when to release bile for its surfactant effect on lipids?” The idea is discussed in The Journal of Medical Hypotheses in 2019.  To do it would require nerve endings in the duodenal mucosa to act as electroreceptors, as previously suggested by Andres et al due to the marked histological similarity between human Brunner’s Glands and proven electroreceptors in the mammalian monotreme species echidna and platypus. If duodenal nerve endings function in this way they would detect the effect of enzymes as they break down lipids or when bile causes micelles. Then, if their data were combined with data from osmoreceptors, the combination would simultaneously detect break up of molecules to make a very sensitive, feedback loop on the progress of digestion. That concept also suggested that the aim of digestion is to render food both iso-osmotic and iso-resistive so it can pass through the cells that line the gut, the first step in absorption.

Biography:

Andrew Sutton has UK board qualifications as an anaesthetist. His MD is the equivalent of a medical PhD from London University. Its focus was how to validate epigastric impedance. He is a clinical pharmacologist specialising in Phase 1 & 2 trials of new medicines. For 14 years he ran his own trial company in a major UK NHS hospital, so he was principal or site investigator in over 100 mainly early-phase trials. He was an expert on UK national research ethics committees for 12 years and is an advisor to the UK Research Integrity Office.
