Why Gut Health Matters More Than You Think: Expert Insights from Nutrition Scientist Dr Emily Prpa

Why Gut Health Matters More Than You Think: Expert Insights from Nutrition Scientist Dr Emily Prpa
Gut health seems to be everywhere right now.
From probiotics and kombucha to fibre supplements and fermented foods, we're constantly being told that a healthy gut is the secret to better digestion, clearer skin, stronger immunity and even improved mental wellbeing.
But what does "gut health" actually mean?
In a recent Elle Sera podcast episode, Alysa sat down with Dr Emily Prpa, award-winning nutrition scientist, registered nutritionist and gut microbiome researcher, to separate fact from fiction and explain why the tiny microbes living inside us may have a bigger impact on our health than we ever imagined.

Your Gut Is Much Bigger Than You Think
When most people think about their gut, they picture their stomach.
In reality, your gastrointestinal tract is a nine-metre-long system stretching from your mouth all the way through your digestive system.
For years, scientists believed the gut's primary role was simply digestion.
Today, research is revealing something much more fascinating.
Inside the gut lives a vast community of microorganisms known as the gut microbiome. These bacteria don't just help digest food — they communicate with the brain, immune system, skin, lungs and other organs throughout the body.
As Dr Prpa explained, we're increasingly discovering that many aspects of health are connected back to the gut.
Why the Gut Microbiome Is Getting So Much Attention
One reason gut health has become such a major area of research is that scientists can now properly study these bacteria.
The findings have been remarkable.
Researchers are uncovering links between the gut microbiome and:
  • Mental health
  • Immune function
  • Skin health
  • Hormonal balance
  • Inflammation
  • Metabolic health
  • Digestive wellbeing
Dr Prpa described the gut as being at the centre of a much larger conversation about whole-body health. Rather than treating systems in isolation, researchers are increasingly recognising how interconnected everything really is.
The Biggest Gut Health Mistake People Make
One of the most common misconceptions Dr Prpa encounters is people immediately cutting foods out whenever they experience digestive symptoms.
Many individuals remove:
  • Gluten
  • Dairy
  • Wheat
  • Certain fruits
  • Entire food groups
Without proper guidance or testing.
The problem?
Your gut bacteria thrive on diversity.
Dr Prpa uses the analogy of a rainforest. A healthy microbiome contains many different species living together in balance. When we dramatically restrict foods, we may unintentionally starve important bacterial species that rely on those foods.
Her message was simple: Gut health is often about inclusion, not exclusion.
Fibre: The Closest Thing to a Gut Health Superfood
If there was one nutrient Dr Prpa believes deserves more attention, it's fibre.
In fact, she described fibre as the closest thing we have to a gut health "silver bullet."
Unfortunately, most people don't consume nearly enough.
Current recommendations suggest adults should aim for approximately 30 grams of fibre daily, yet many people consume far less.
Excellent fibre sources include:
  • Fruits
  • Vegetables
  • Whole grains
  • Beans
  • Lentils
  • Chickpeas
  • Nuts
  • Seeds
  • Herbs and spices
Why is fibre so important?
Because our gut bacteria feed on it.
When bacteria ferment fibre, they produce compounds called short-chain fatty acids that support gut integrity, reduce inflammation and contribute to overall health.

Your Gut and Your Brain Are Constantly Talking
One of the most fascinating topics discussed was the gut-brain axis.
Many of us have experienced:
  • Butterflies before a presentation
  • Feeling sick with nerves
  • Digestive upset during stressful periods
These are real examples of communication between the brain and the gut.
Conditions such as Irritable Bowel Syndrome (IBS) highlight this relationship particularly clearly.
Research shows that stress, anxiety and emotional wellbeing can significantly influence digestive symptoms, which is why approaches such as:
  • Breathwork
  • Yoga
  • Meditation
  • Hypnotherapy
are increasingly being incorporated into evidence-based IBS management.

Why Stress Can Wreck Your Digestion
Dr Prpa explained that chronic stress doesn't just affect mood.
It can:
  • Alter gut bacteria composition
  • Increase inflammation
  • Affect bowel habits
  • Influence food cravings
  • Disrupt digestion
The hormone cortisol plays a central role here.
When we're stuck in "fight or flight" mode, digestion becomes a lower priority for the body. This is one reason digestive symptoms often worsen during periods of prolonged stress.
One of the simplest tools available?
Breathing.
Activating the vagus nerve through slow, controlled breathing can help shift the body into "rest and digest" mode, supporting both digestive and overall health.

Probiotics vs Prebiotics: What's the Difference?
It's easy to get confused by the terminology.
Dr Prpa explained the difference clearly:
Probiotics
These are live microorganisms that can provide health benefits when consumed in adequate amounts. Examples include:
  • Live yoghurts
  • Fermented milk drinks
  • Certain probiotic supplements
Prebiotics
Prebiotics are essentially food for your existing gut bacteria.
Common sources include:
  • Onion
  • Garlic
  • Asparagus
  • Tomatoes
  • High-fibre plant foods
Prebiotics help beneficial bacteria grow and thrive.
Her advice? Food first.
A varied, fibre-rich diet remains the foundation of good gut health.

What About Antibiotics?
Antibiotics can be life-saving when needed.
However, because most antibiotics are broad-spectrum, they don't only eliminate harmful bacteria—they can also affect beneficial microbes living in the gut.
The good news is that the microbiome can recover.
Supporting recovery through:
  • A fibre-rich diet
  • Diverse plant foods
  • Appropriate probiotic use where suitable
may help encourage a healthier rebound following treatment.

Gut Health, Hormones and Menopause
For women, one particularly exciting area of research involves the connection between gut bacteria and hormones.
Dr Prpa explained that specific gut bacteria are involved in processing and recycling oestrogen. This collection of bacteria is sometimes referred to as the "estrobolome."
As oestrogen levels naturally decline during perimenopause and menopause, researchers are investigating whether improving gut microbiome diversity may help support hormonal balance and potentially reduce some menopausal symptoms.
While research is still developing, the findings so far are extremely promising.

Gut Health and Women's Health Conditions
The discussion also touched on conditions affecting many women, including:
  • PCOS
  • Endometriosis
  • Fertility challenges
Emerging research suggests women with some of these conditions may experience differences in their gut microbiome composition compared with healthy controls.
Although scientists are still investigating exactly how these relationships work, maintaining good gut health appears to be an important part of supporting overall wellbeing.

The Connection Between Gut Health and Skin
Ever noticed your skin breaking out during periods of stress, illness or poor diet?
There may be a reason.
Dr Prpa discussed growing evidence linking gut health to skin conditions such as:
  • Acne
  • Rosacea
  • Eczema
  • Inflammatory skin concerns
Many of these conditions involve inflammation, which may be influenced by the gut microbiome and the compounds it produces.
While skincare remains important, healthy skin often starts from within.

Four Things You Can Do Today to Support Your Gut
Dr Prpa's recommendations were refreshingly practical.
Rather than chasing miracle supplements, focus on four foundations:
1. Increase Fibre
Aim to gradually increase the variety and quantity of fibre-rich foods in your diet.
2. Move More
Regular movement supports digestive health and microbiome diversity.
3. Prioritise Sleep
Your gut bacteria thrive when your sleep is consistent and restorative.
4. Manage Stress
Simple breathing exercises, mindfulness and relaxation techniques can have a surprisingly powerful impact on gut function.

Where Elle Sera Fits In
One of the strongest messages throughout the episode was that health doesn't happen in isolation.
Your gut influences your hormones, energy, skin, mood and overall wellbeing. Supporting your body with good nutrition, movement, sleep and stress management creates the foundation upon which everything else is built.
At Elle Sera, we share this whole-body approach to wellness.
Whether it's supporting daily nutritional intake through Golden Pill, promoting relaxation and recovery through Magnesium, or helping nourish the body with Liposomal Tripeptide Collagen, the goal is always to support the body's natural systems rather than chasing quick fixes.

The Bottom Line
The gut microbiome may be one of the most exciting areas of modern health research.
Far from being simply a digestive system, the gut influences multiple aspects of health—from mood and hormones to immunity, skin and overall wellbeing.
The best part?
Many of the most effective ways to support it are simple:
  • Eat more fibre
  • Diversify your plant foods
  • Move your body
  • Sleep well
  • Manage stress
As Dr Prpa reminds us, every meal isn't just feeding you.
It's feeding trillions of microbes that help support your health every single day.
