Taking Control of Your Family’s Health with Functional Medicine || A Conversation with Dr. Liz Corcoran

Intro
If you’ve ever stood in the kitchen holding a processed packet of something with seventeen ingredients you can’t pronounce, wondering whether you’re overthinking it… you’re not alone. Most mothers I speak to aren’t trying to become wellness gurus. They’re just trying to keep their families, fed, healthy, keep their own energy up, and stop the constant cycle of “why are we always ill?”
And yet modern life doesn’t make that easy. We’re surrounded by convenience food, confusing advice, and the quiet feeling that health is something that happens to us and is not something we can shape.
In this episode of The Real Life. Real Kitchen Podcast, I’m joined by Dr. Liz Corcoran, a Functional Medicine doctor and psychiatrist, for a practical, thought-provoking conversation about what “root cause” care actually means. We talk about why the body can’t be treated like separate compartments, how food shapes biology, and what small, realistic changes can do for family health over time.
About the Guest
Dr. Liz Corcoran is a Functional Medicine doctor and psychiatrist, passionate about empowering people to restore their health by changing how they interact with their world. She graduated from Royal Free University College London (2005), completed MRCPsych psychiatry training, and is a Certified Practitioner with the Institute of Functional Medicine.
Liz’s work is shaped not only by clinical expertise, but by lived experience through her own and her family’s health struggles, which ultimately led her into Functional Medicine. You can find her at bit.ly/drlizcorcoran and on Instagram @drlizcorcoran.
Episode Highlights
1. Why “Good Medicine” Looks at the Whole Person
Liz has a wonderfully blunt way of putting it: the body isn’t a series of soloists; it’s an orchestra.
In conventional healthcare, we often end up in silos. One clinician looks at mood. Another looks at skin. Another looks at digestion. Another focuses on blood sugar. But when you actually sit with a real human being, you quickly realise the symptoms rarely stay politely in their lane.
Functional Medicine, Liz explains, starts with a different assumption: everything is connected. Your history matters. Your stress matters. Your sleep matters. Your food matters. And sometimes the very moment your health changed wasn’t a virus or a diagnosis… it was a grief, a move, a chronic season of overwhelm.
That whole-person lens is quietly countercultural, especially in modern motherhood, where we often feel like we’re meant to keep functioning indefinitely – like automatons – regardless of what our bodies are signalling.
2. Psychiatry vs Psychology: A Helpful Distinction for Mums
We took a moment in the episode to clarify something many people aren’t sure about: what’s the difference between psychiatry and psychology?
Liz explains that psychiatrists are medical doctors; trained first in the body (anatomy, physiology, chronic disease, acute illness), then specialising in mental health. Psychologists and therapists have different training pathways, often focusing more on psychological development, therapy modalities, and research.
Why does this matter in a motherhood podcast episode about family health?
Because it reinforces the central idea of the conversation: mental health is not disconnected from the body. A mum can be anxious and also depleted. A child can be “behavioural” and also exhausted, inflamed, or undernourished. Liz’s dual background is what makes her approach so grounded; she’s not treating moods as if they float in mid-air but are part of a puzzle, one that we as mums can help put back together, one piece at a time.
3. Functional Medicine: Root Causes, Not Whack-a-Mole
Liz describes the classic experience many families have with modern healthcare. You may find this familiar. You treat one symptom, then another pops up. You suppress a problem, but the underlying pattern stays.
Functional Medicine for family health is different. Instead of asking only, “What diagnosis is this?” it also asks:
- What’s driving this pattern?
- What’s changed over time?
- Which systems are under strain?
- What does this person need to restore function?
And here’s the part that tends to land like a small shock: you likely have more control than you realise.
Not perfection-control. Not “do everything right” control. But genuine autonomy, especially when it comes to food, sleep, movement, stress, and the home environment.
4. The Microbiome: The “Village” Living Inside You
If the word microbiome makes you think of a wellness influencer holding homemade kombucha, stay with me — Liz explains it in a way that actually makes sense.
The microbiome is the community of bacteria, viruses, and fungi living in and around us, particularly in the gut. Liz describes it as a “cushion between us and the outside world”, helping the body digest food, regulate immune responses, produce certain nutrients, and even influence wellbeing through the gut-brain connection.
This is one reason diet matters so much: we’re not only feeding ourselves… we’re feeding the ecosystem inside us.
And yes, Liz also highlights how modern life has altered this ecosystem: antibiotics, certain medications, and ultra-processed diets can reduce diversity… which in gut terms is not a good thing.
5. Practical Family Health: Small Changes That Actually Stick
This is where the episode becomes especially helpful for busy mums.
Liz is very clear: you don’t need to transform your family diet overnight. In fact, trying to do everything at once often backfires, especially for children with sensory sensitivities or strong food preferences, never mind mums juggling all the things!
Her approach is what I’d call slow living for health:
- Start by eating together more often, even if it’s not perfect
- Add one “real food” side to a familiar meal
- Make changes gradually so they become normal
- Focus on food quality where you can, within budget
- Avoid “forever foods” (if it lasts forever, it probably shouldn’t be dinner)
She also shares practical tools for children, like a “rainbow” approach to fruit and vegetables, helping kids look for colour and variety rather than obsessing over rules.
And perhaps the most empowering line of the whole episode is this:
“Food is information; it can change your biology.”
Which is both sobering and hopeful, isn’t it?
Quick Takeaways
- The body is connected; it’s not a set of separate problems
- Healing often begins with trust, time, and relationship
- Functional Medicine for family health looks for root causes, not just symptom relief
- The microbiome supports immunity, digestion, and even wellbeing
- Food is powerful, but change works best when it’s incremental
- Family meals aren’t just nutrition… they’re connection and regulation
