Welcome back to Functional Medicine Bitesized! It's been a while since we recorded an episode but we are back and I have plenty of exciting guests lined up to be interviewed.

In this episode, I chat once again with gut microbiome expert Elena Panzeri about what modern microbiome testing can realistically tell us. We explore why the gut should be seen as a complex ecosystem, the limits of using tests for diagnosis, the role of specific bacteria such as Fusobacterium in cancer risk, and why markers like alpha diversity matter more than individual “good” or “bad” bugs. Elena also explains why fiber and prebiotics often outperform probiotics, how factors like diet, medications, and stress over a lifetime shape the microbiome, and why test results must always be interpreted in a holistic clinical context rather than in isolation.

I'm sure you will enjoy this chat with Elena just as much as you enjoyed the first one.

In this episode of Functional Medicine Bite Sized, I sat down with Kayla Butera, International Educator for Body Bio, to explore the often-misunderstood world of fats, fatty acids, and targeted nutraceuticals—without getting overwhelmingly technical.

There was lot's to cover and some of they key points we discussed were:

• Why both linoleic acid (omega‑6) and ALA (omega‑3) are essential
• How fatty acid quality, oxidation, and processing affect mitochondrial and cardiovascular health
• What “liposomal” should mean, why it’s often misused, and when liposomal delivery is worth the extra cost
• Why short‑chain fatty acid butyrate is a key “gift” from a healthy microbiome

In this episode of Functional Medicine Bitesized, I had the opportunity to sit down with Chris Fitzmaurice, clinical exercise physiologist at the University of Miami Health System and certified cancer exercise specialist, to explore the powerful role of exercise as medicine in cancer care.

It was a fascinating chat unpacking how aerobic and resistance training act as “molecular medicine”—modulating inflammation, supporting the immune system, and changing the tumor microenvironment to make standard treatments like chemotherapy and radiation more effective and better tolerated. Chris used a brilliant analogy explaining how exercise can be thought of as turning the tumor’s “paradise beach” into “Antarctica,” disrupting its ability to thrive.

Listen in to hear more about personalised exercise prescription for different cancer types and stages, the emerging science of myokines and exerkines as well as the mental health impact of movement, including how exercise can prevent and treat depression in cancer survivors

We also discussed highly practical strategies including one of my all time favourites, "exercise snacks" and why, when it comes to exercise, anything is better than nothing.
