From gut to glucose: the potential of probiotics in diabetes care Mar 11, 2025

Show notes

Type 2 diabetes is a metabolic disorder characterised by high blood sugar levels due to insulin resistance or insufficient insulin production. It's a growing global health concern. While diet, exercise and medication form the cornerstone of diabetes management, researchers are continually exploring new avenues to improve blood sugar control. One such area gaining traction is the use of probiotics that can alter gut and metabolic health. But can these tiny microorganisms make a meaningful difference for people with type 2 diabetes? That’s what I explore in this episode.

From FODMAPs to fibre: navigating dietary treatments for IBS Jan 28, 2025

Show notes

Irritable bowel syndrome (IBS) is a common gastrointestinal issue marked by abdominal pain, bloating, diarrhoea and constipation. This chronic condition can lead to anxiety, depression and a reduced quality of life. With no definitive trigger or treatment, managing IBS can be challenging. However, diet changes can positively influence IBS. In this podcast episode, I’ll outline evidence for various approaches, from supplements like probiotics right through to low-FODMAP diets.

Strength in ageing: the role of protein and resistance training Dec 10, 2024

Show notes

We’re all getting older and living longer lives than ever before. But as we age, we are faced with a higher risk of nutritional frailty. This is marked by unintentional weight loss, loss of muscle mass and strength which increases the likelihood of disability. In this podcast episode, I highlight how our nutrition needs change as we age and why a firm focus is needed in preserving muscle mass through a combination of resistance exercise and additional protein.

Maximising muscle gains with creatine: how well does it work? Nov 12, 2024

Show notes

Creatine is one of the most well-researched and effective sports nutrition supplements for improving exercise performance. So it is no surprise that interest in using creatine supplements to enhance performance during intense activity has grown dramatically over the last few years. One of the most common ‘use cases’ for creatine supplements is for muscle and strength gains. This makes creatine a popular choice by strength and power sports athletes, bodybuilders and recreational exercisers to supplement their resistance training. In this podcast episode, I dig deeper into what creatine is, how it may work and importantly: what the latest scientific evidence has to say about how it performs in maximising muscle gains.

Is hydrogen water healthy or a hoax? Aug 27, 2024

Show notes

Heard about hydrogen water? It is regular water that has extra hydrogen infused in it and it’s one of the latest health trends with proponents claiming it will fight off disease, reduce inflammation, boost energy, improve mental health and enhance athletic performance. That’s quite a list of impressive claims. But what does the research have to say? That’s what I explore in this podcast to see if hydrogen water can live up to the hype or if it should be labelled the latest health hoax.

Maximising muscle: the role of protein type and timing Jul 09, 2024

Show notes

No one nutrient gets greater focus in the sports and performance world than protein – and for good reason. Protein builds and powers our muscles and with that comes strength and performance gains – something just about every athlete wants to have more of. Understanding how dietary protein improves muscle mass, strength and performance is crucial. Two topics that are hotly debated are the role of protein type and timing around a resistance training program. And they’re the topics I’m going to tackle in this podcast episode.

Can probiotics help fight age-related muscle loss? Jun 04, 2024

Show notes

Some aspects of ageing may be inevitable, but when it happens together with an accelerated loss of weight, muscle mass and strength it makes an older person much more susceptible to disability, poor quality of life and earlier death. The condition is called sarcopenia and it is underpinned by chronic inflammation. Diet and lifestyle changes can go a long way in preventing and treating sarcopenia and inflammation. And now research is adding to this by looking at the role of probiotics as a way to influence the gut microbiome and with that, the muscle loss and inflammation seen in sarcopenia. That’s what I’ll be exploring in this podcast.

Arthritis relief: can collagen supplements help? Mar 05, 2024

Show notes

Interest in collagen supplements continues to grow – and for good reason. That’s because despite rubbish claims that are way off the mark that there is ‘no evidence they work’ and ‘all the research is funded by the collagen industry’, the reality is very different. In past podcasts I’ve delved into the topic of hydrolysed collagen supplements and skin health and where there are now dozens of blinded randomised controlled trials showing a benefit in increasing skin moisture and elasticity and reducing wrinkles – with many of the studies free from any conflict of interest and all supported by plausible mechanisms as to why collagen, and not other protein sources, can do this. But for this podcast, I want to focus on one of the other reasons that people may take collagen: and that’s to give relief from joint pain and stiffness. So for this episode, I’m going to focus on arthritis and outline what the clinical evidence says and what unique biological mechanisms could be at play to support a unique effect of collagen supplements.

Are probiotics effective in IBS? Jan 30, 2024

Show notes

Irritable bowel syndrome is one of the most common gastrointestinal complaints. With no single identified trigger or treatment, IBS can be a minefield for a person to try and get on top of. Dietary changes like a low-FODMAP diet, supplements and stress modification all have a role to play. Another emerging treatment for IBS are probiotics. Probiotics may improve IBS symptoms by changing the gut microbiota and their metabolite production which can change gut motility, inflammation and gut hypersensitivity. In this podcast, I’ll look at the evidence for the use of probiotic supplements in IBS.

Maternal probiotics and their effect on infant health Dec 05, 2023

Show notes

The establishment and development of the microbiome in the early stages of life can play a pivotal role in affecting our health throughout life. The formation of our microbiome happens during the perinatal period where it is influenced by the interaction between the microbiomes of mothers and infants. The microbial composition of breast milk plays an important part in this process. The microbiome of breast milk is also influenced by the gut microbiome of the mother through what is termed the gut-breast axis. In this podcast, I'll explore these mother-infant microbiome links and discover what the scientific evidence has to say about the potential for maternal probiotic supplements having a positive influence on the health of mother and infant.
