HSW 47: Gut Health, Probiotics and Sleep with Dr Jason Hawrelak

This week I had the absolute pleasure of interviewing one of the leading experts on gut health, Dr Jason Hawrelak who is a researcher, lecturer, naturopath, and nutritionist based in Hobart with over 17 years of clinical experience.

Whilst there’s an enormous amount of research on some of the damaging effects a poor diet has on our gut health (high saturated fats, low fibre, and high sugar), another less known factor is how sleep disruption can have negative implications on the state of our gut health too.

Given shift workers are prone to circadian rhythm disruption or a disruption to our sleep/wake cycle, what most people are unaware of is how this sleep disruption can actually disrupt the composition of our gut microbiota which can subsequently impair the lining of the digestive tract, leading to an increase in the permeability of the gut, otherwise known as “leaky gut”.

Dr Hawrelak goes into detail on some of the mechanisms behind this increase in intestinal permeability, along with discussing the difference between pre and probiotics; capsules versus powder; and when is the best time to take your probiotics in order to maximize their effectiveness.
