Frequently Asked Questions
Your gut health questions, answered
Karen Ball is a clinical nutritionist specialising in gut health, IBD, and women's hormonal health. Here's what clients ask most often.
Gut Health Basics
What is gut health and why does it matter?
Gut health refers to the balance and function of your entire digestive system - from how well you digest and absorb nutrients, to the trillions of bacteria living in your gut (your microbiome).
A healthy gut does far more than just process food. It influences your immune system, mood, energy, hormones, skin, and even how well you sleep. When your gut is out of balance, symptoms like bloating, irregular bowel movements, fatigue, brain fog, and inflammation can follow.
The good news? The gut is highly responsive to nutrition and lifestyle changes.
Is bloating normal?
Some degree of bloating after meals can be completely normal - your digestive system is working, and gas is a natural byproduct of fibre fermentation. But significant daily bloating, persistent discomfort, or bloating that affects your quality of life is not something you just have to put up with.
It's your gut's way of signalling that something needs attention. Common causes include low microbiome diversity, dysbiosis (imbalance of gut bacteria), food intolerances, slow gut motility, stress, and hormonal changes. Identifying the underlying cause - rather than just eliminating foods - is what leads to lasting improvement.
What are the signs of an unhealthy gut?
The gut communicates through symptoms - and it's worth knowing what to look for.
Common signs that your gut may need some attention include:
-
frequent bloating or excessive gas
-
constipation or diarrhoea (or swinging between both)
-
abdominal pain or cramping
-
feeling tired or sluggish after eating
-
brain fog
-
poor sleep
-
skin issues like eczema or breakouts
-
getting sick more often than you'd expect
Less obvious signs include strong sugar cravings, mood changes, and food sensitivities that seem to be getting worse over time. Because the gut is connected to so many systems in the body - immune, hormonal, neurological - an unhealthy gut can show up in ways that don't immediately seem digestive at all.
The key thing to know: these symptoms are signals, not just inconveniences. They're worth paying attention to.
How long does it take to improve gut health?
The gut is genuinely one of the most responsive systems in the body. Many people notice meaningful changes within 4 - 6 weeks of consistent dietary and lifestyle changes - reduced bloating, more regular bowel movements, better energy.
That said, deeper microbiome shifts and more complex conditions like IBD or long-standing IBS typically take 3 - 6 months of sustained change to show significant improvement. There's no magic timeline - it depends on where you're starting from, how consistently you implement changes, and what's driving your symptoms.
What matters is building habits you can actually maintain, not a 30-day plan that's unsustainable.
What foods are good for gut health?
The short answer: variety. The single biggest predictor of a healthy gut microbiome is how many different plant foods you eat each week.
Research suggests aiming for 30 different plant foods per week - and that includes vegetables, fruits, wholegrains, legumes, nuts, seeds, herbs, and spices.
Beyond variety, some specific standouts for gut health include fermented foods (yoghurt, kefir, sauerkraut, kimchi, miso) which directly support microbiome diversity; prebiotic-rich foods like garlic, onion, leeks, asparagus, and oats which feed beneficial bacteria; and oily fish like salmon and sardines which reduce gut inflammation.
It's also worth noting what are not good gut foods - ultra-processed foods, excessive alcohol, and low-fibre diets are consistently linked with reduced microbiome diversity.
You don't need to be perfect, but your gut will thank you for making plants the foundation of most meals.
Do I need to take probiotics?
Probiotics can be useful - but they're not the first thing most people need, and not all probiotics are equal.
The research on probiotics is very strain-specific: a probiotic that helps IBS may do nothing for IBD, and vice versa. A probiotic that helps with bloating, or diarrhoea, is very specific.
For most people, the single most impactful thing you can do for your microbiome is increase the diversity and quantity of plants in your diet - this feeds the bacteria already in your gut. Fermented foods also provide live bacteria with excellent evidence behind them.
If you're considering a probiotic supplement, getting guidance on the right strain for your specific situation is worthwhile, rather than picking something off the shelf.
Do I need to go gluten free to improve my gut health?
Not unless you have coeliac disease or a diagnosed non-coeliac gluten sensitivity. For most people, there's no evidence that removing gluten improves gut health - in fact, many gluten-free products are lower in fibre and nutrients than their wholegrain counterparts.
The reason some people feel better going gluten-free is often because they've also cut out ultra-processed foods, fast foods, refined carbohydrates, or a group of foods containing fructans - and that's what's driving the improvement, not the gluten removal itself.
Gluten is an individual discussion, depending on what is happening in the body - a case by case assessment whether removal will be beneficial for you.
If you suspect gluten is a problem for you, it's worth getting properly tested for coeliac disease before removing it from your diet, as the test requires you to be eating gluten to be accurate.
What are fermented foods and should I be eating them?
Fermented foods are foods that have been transformed by beneficial bacteria or yeasts - think yoghurt, kefir, sauerkraut, kimchi, miso, tempeh, and sourdough bread. They're one of the most well-researched dietary additions for gut health.
Regular consumption of fermented foods has been shown to increase microbiome diversity, reduce inflammatory markers, and support digestive function.
Most people benefit from including them - even small amounts daily can make a difference.
If you have IBD, IBS or are very sensitive, starting slowly and choosing lower-lactose options (like lactose-free kefir or sauerkraut) is often the best approach.
Making your own fermented foods is also a surprisingly accessible and cost-effective option.
Perimenopause & Women's Gut Health
Why am I so bloated during perimenopause?
Bloating is one of the most common, and frustrating, symptoms women experience during perimenopause.
Here's what's happening: as oestrogen and progesterone fluctuate, digestion slows down, gut motility changes, and the gut microbiome itself shifts. This can mean food sits in the digestive system longer, producing more gas.
Lower fibre intake, changes in stress hormones, and water retention can make it worse.
The good news is that targeted nutrition changes including increasing specific types of fibre, adding fermented foods, and supporting the microbiome, can make a real difference to bloating at this life stage.
How does the gut microbiome change during perimenopause
and menopause?
Research shows that the gut microbiome changes significantly around menopause - and oestrogen plays a big role in this. As oestrogen declines, the diversity of gut bacteria tends to decrease, which can affect digestion, metabolism, immune function, and even mood.
A less diverse microbiome is also linked to increased inflammation and slower gut motility, which contributes to symptoms like constipation and bloating.
The positive side: diet is one of the most powerful ways to support microbiome diversity at any life stage. Prioritising plant variety, fermented foods, and fibre-rich whole foods can meaningfully shift the microbiome even after menopause.
Can improving gut health help with perimenopause symptoms?
More than most people realise. The connection between gut health and perimenopause symptoms runs deeper than digestion. A specific community of gut bacteria called the estrobolome plays a direct role in how your body processes and recirculates oestrogen. When these bacteria are out of balance, oestrogen metabolism is disrupted, which can intensify hormonal symptoms like hot flushes, mood changes, and irregular cycles.
Beyond the estrobolome, gut inflammation affects the production of neurotransmitters like serotonin (around 90% of which is produced in the gut), which influences mood, sleep, and anxiety. A healthier gut also supports better nutrient absorption, which matters enormously during perimenopause when your needs for certain nutrients are changing.
Focusing on gut health during perimenopause isn't a separate goal from managing hormonal symptoms. In many cases, they're the same goal.
I've cut out lots of foods but still have gut symptoms - what's going on?
This is one of the most common situations Karen sees, and it's genuinely frustrating. Here's the thing: removing foods is rarely the solution to gut symptoms, because elimination treats the symptom, not the cause.
When you cut out a food and feel better temporarily, it often means that food was aggravating an underlying issue, not that it was the root cause. Remove the food, the irritation decreases. But the underlying imbalance, whether that's dysbiosis, poor gut motility, low digestive enzyme production, stress, or a disrupted gut barrier, is still there.
Over time, excessive elimination can actually make things worse. A restricted diet means fewer diverse plants, which reduces microbiome diversity, which makes the gut more reactive, which leads to more food sensitivities.
It can become a vicious cycle that's hard to break.
The goal isn't to find more foods to cut out. It's to understand what's driving the sensitivity in the first place. That's where a personalised nutrition approach tends to turn things around.
Can nutrition help with perimenopause symptoms beyond gut health?
Absolutely! Nutrition has a significant impact on many perimenopause symptoms, not just digestion.
Blood sugar balance is closely linked to energy, mood, cravings, and weight changes during this stage - and diet is one of the most effective tools to stabilise it.
Anti-inflammatory eating patterns can reduce joint pain, brain fog, and fatigue. Adequate protein and specific nutrients support muscle and bone mass, which naturally declines with age.
And gut health itself influences oestrogen metabolism, meaning what you eat can affect your hormonal balance more than most people realise.
A personalised approach looks at the whole picture, not just one symptom.
Why is fibre important for women in midlife, and how much do I need?
Fibre is arguably the most important nutrient most women aren't eating enough of - especially in midlife. It feeds the beneficial bacteria in your gut, supports regular bowel movements, helps regulate blood sugar, reduces cholesterol, and plays a role in oestrogen metabolism.
The recommended intake is around 25 - 30g per day, but most Australians fall well short of this. The key is increasing fibre gradually (a sudden jump can actually cause more bloating initially) and focusing on variety - different types of fibre from vegetables, fruits, legumes, wholegrains, nuts, and seeds each feed different bacteria.
If you're not sure how to build your fibre intake without discomfort, that's exactly what a nutrition consultation can help with.
What foods help with bloating?
Reducing bloating isn't about cutting everything out - it's about understanding what your gut needs.
Some foods that commonly support better digestion and reduce bloating include fermented foods like yoghurt, kefir, sauerkraut, and kimchi; cooked vegetables (easier to digest than raw for some people); ginger and peppermint tea; adequate water intake; and a gradual increase in dietary fibre from wholegrains, legumes, and vegetables.
Triggers vary from person to person, so what works for one person may not work for another. That's why personalised nutrition support is so valuable - rather than guessing, we identify what's actually driving your bloating.
Inflammatory Bowel Disease (IBD)
- Crohn's Disease and Ulcerative Colitis
What is the difference between IBD and IBS?
They sound similar and are often confused, but they're very different conditions. IBD (Inflammatory Bowel Disease) is an autoimmune condition that causes chronic inflammation and physical damage to the digestive tract. It includes Crohn's disease and ulcerative colitis, and is diagnosed through scopes, imaging, and biopsies. IBD is a serious medical condition that requires ongoing management, often including medication.
IBS (Irritable Bowel Syndrome) is a functional gut disorder, meaning the gut is functioning differently but there's no visible structural damage or inflammation. Symptoms like bloating, cramping, constipation, and diarrhoea can be just as debilitating, but the underlying mechanism is different. IBS is typically diagnosed based on symptoms once other conditions have been ruled out.
Both conditions benefit significantly from nutrition support, but the approach is quite different. IBD management often also requires close coordination with a gastroenterologist.
How can a nutritionist help if I have IBD?
IBD is a condition where nutrition support can make a genuine, measurable difference, yet it's often one of the last things people are offered. Here's where a nutritionist experienced in IBD can help.
First, identifying and addressing nutrient deficiencies, which are extremely common in IBD and frequently missed. Iron, vitamin D, B12, zinc, and magnesium are among the most prevalent, and correcting them can significantly improve energy, immune function, and overall wellbeing.
Second, building an eating approach that works across different phases of the condition, both during flares and in remission, so you're not starting from scratch every time symptoms change.
Third, rebuilding microbiome diversity during remission, which emerging research links to longer periods of disease control.
And fourth, cutting through the overwhelming amount of conflicting dietary advice online and replacing it with a clear, personalised plan based on your specific disease location, history, and goals.
Living with IBD is hard enough. Nutrition support should make it simpler, not more complicated.
What can I eat with IBD (Crohn's disease or ulcerative colitis)?
There is no single IBD diet - that is the reality of a condition that looks very different from person to person and flare to flare. That said, there are well-supported nutrition principles.
During a flare, the focus is typically on foods that are easier to digest, lower in insoluble fibre, and gentle on the gut - think well-cooked vegetables, white rice, eggs, fish, chicken and bone broths.
During remission, the goal shifts to rebuilding the microbiome, addressing nutrient deficiencies (iron, B12, zinc, and vitamin D are commonly low in IBD), and gradually increasing dietary variety, including fermented foods.
What triggers symptoms varies widely between individuals, which is why working with a nutritionist experienced in IBD is so valuable - rather than cutting out large food groups unnecessarily.
Can diet help prevent or reduce IBD flares?
Diet doesn't cause IBD, but it absolutely can influence how often and how severely flares occur.
Research supports an anti-inflammatory eating pattern as beneficial for IBD - one that emphasises omega-3-rich foods (fatty fish, walnuts, flaxseed), colourful vegetables and fruits, adequate protein, and fermented foods where tolerated.
Ultra-processed foods, high-fat fast food, alcohol, and artificial emulsifiers have been associated with increased inflammation and disrupted gut barrier function.
Stress management and sleep also play a significant role in IBD flare frequency, so a holistic approach - looking at nutrition and lifestyle together - tends to produce the best outcomes.
Is it safe to eat fibre when you have IBD?
This is one of the most common questions from people with IBD, and one of the most misunderstood. Many people with IBD are told to avoid fibre, but the evidence is more nuanced.
During an active flare, reducing insoluble fibre (found in raw vegetables, wholegrains, whole nuts and seeds, and skins) may ease symptoms. However, soluble fibre - found in oats, psyllium, cooked carrots, and legumes - is often well-tolerated even during a flare and actively supports gut healing.
During remission, gradually reintroducing a variety of fibres is important for microbiome health and reducing long-term inflammation.
The type of fibre, how it's prepared, and where you are in your IBD cycle all matter. This is not a one-size-fits-all situation.
Are there foods I should avoid with IBD?
The honest answer is that there's no universal IBD avoid list, because IBD looks different from person to person, and what triggers symptoms in one person may be completely fine for another. That said, there are some consistent patterns that Karen sees time and time again in clinic.
During an active flare, foods that tend to aggravate symptoms for many people include high-insoluble-fibre foods like raw vegetables, wholegrain skins, and seeds; spicy foods; high-fat or fried foods; caffeine; alcohol; and dairy for those who are lactose sensitive. These aren't necessarily permanent avoidances, just foods that can be harder to tolerate when the gut is already inflamed.
Outside of flares, the research points to a few categories worth limiting regardless of symptoms. Ultra-processed foods, artificial emulsifiers and gums (found in many packaged foods, sauces, and low-fat products), high-fat fast food, and alcohol have all been associated with increased gut inflammation and a disrupted gut barrier, which is particularly relevant in IBD.
The important caveat: over-restriction is a real and common problem in IBD. Many people end up on extremely limited diets that are nutritionally inadequate and socially isolating, without those restrictions actually improving their symptoms. If you've been cutting out more and more foods without significant improvement, it's worth working with someone who can help you identify what's genuinely problematic versus what you're avoiding unnecessarily.
The goal is the least restrictive diet that keeps you well, not the most restrictive diet you can tolerate.
What nutrients are commonly deficient in people with IBD?
Nutrient deficiencies are extremely common in IBD, and often go unaddressed.
Iron deficiency anaemia is one of the most prevalent - caused by blood loss, poor absorption, and restricted diets. Vitamin D, vitamin B12, folate, zinc, magnesium, and calcium are also frequently low, particularly in Crohn's disease where the small intestine is commonly affected.
These deficiencies don't just make you feel tired - they affect immune function, wound healing, bone density, mood, and overall disease management.
Regular monitoring and targeted nutrition support are important parts of living well with IBD, not just managing flares.
Working with Karen
What qualifications does Karen have?
Karen holds a Bachelor of Health Science in Complementary Medicine, as well as an Advanced Diploma of Nutritional Medicine, giving her a strong clinical and evidence-based foundation in nutrition.
She is a clinical nutritionist with a special interest in gut health, IBD, and women's hormonal health.
Her practice is food-first and evidence-informed, meaning recommendations are grounded in current research and tailored to each individual, not based on trends or one-size-fits-all protocols.
What does a nutritionist do, and how is it different from a dietitian?
Both nutritionists and dietitians are trained in food and nutrition science, though their registration pathways differ. Karen at The Foodie Nutritionist holds a Bachelor of Health Science as well as an Advanced Diploma of Nutritional Medicine, giving her a strong clinical and evidence-based foundation.
The focus of nutrition consultations is holistic, personalised, and food-first: understanding what's driving your symptoms, educating you on the 'why' behind recommendations, and building sustainable strategies - not handing you a generic meal plan and sending you on your way.
What happens in a nutrition consultation with Karen?
Every consultation starts with understanding you as a whole person - your symptoms, health history, diet, lifestyle, stress, sleep, and goals.
Karen takes time to listen, ask the right questions, and identify the patterns contributing to how you feel.
From there, you'll receive personalised, practical recommendations you can realistically implement - not an overwhelming list of things to change all at once.
Follow-up consultations build on your progress and adjust the approach as needed. Many clients say the biggest shift is simply feeling heard and having clarity on what's actually going on in their body.
How much does a nutrition consultation cost?
Initial consultations are $195.
Follow-up consultations (for clients seen within the past 12 months) are $170.
A free Discovery Call is also available - a no-obligation conversation to talk through your health concerns and explore what working together would look like.
A Gut Microbiome Testing Package is available at $720, which includes a comprehensive Microba microbiome test, a full microbiome report, and a detailed nutrition consultation with personalised recommendations.
Can I claim nutrition consultations on my health fund?
Yes, many Australian health funds offer rebates for nutrition consultations. As a registered ANTA member nutritionist, Karen is recognised as a provider by the following funds:
-
HBF Health
-
Health Partners
-
Latrobe Health Services, Mildura Health Fund, Peoplecare Health Insurance, Phoenix Health Fund, see-U by HBF (formerly CUA Health), St Lukes Health (including Astute Simplicity Health), Westfund Health Insurance
-
Australian Health Management (AHM)
-
Australian Unity (members prior to year 2000)
-
GU Health

-
NIB (including AAMI, APIA, ING, Qantas Health Insurance, and Suncorp)
The rebate amount varies depending on your level of extras cover and your specific policy. To check if you're covered, look at the extras section of your policy or call your fund and ask whether nutrition consultations are included.
If your fund isn't on the list, it's still worth checking directly as policies do change.
This list is current as at July 2026.
Do you offer online consultations?
Yes. Consultations are available both in-person and online, making it easy to get personalised gut health support no matter where you're located. Online consultations are just as thorough and personalised as face-to-face appointments.
If you're unsure whether a consultation is right for you, the free Discovery Call is a great first step.
What is gut microbiome testing and do I need it?
Gut microbiome testing analyses the thousands of species of bacteria, fungi, and other microorganisms living in your gut.
The test Karen offers uses Microba's microbiome tests - one of the most comprehensive clinical grade microbiome tests available in Australia, which sequences the entire DNA of your gut microbiome rather than just identifying a limited panel of bacteria.
This gives a far more detailed picture of your gut ecosystem: which bacteria you have, what they're producing, how diverse your microbiome is, and what this means for your specific health concerns.
It's not essential for everyone, but for people with complex gut symptoms, IBD, persistent IBS, or those who want a deep dive into their gut health, it can be a powerful tool for personalisation.
I've already tried lots of things and nothing has worked.
Can nutrition actually help?
This is one of the most common things Karen hears - and one of the most understandable.
If you've tried elimination diets, supplements, and wellness programs without lasting results, it's often because the approach was focused on removing things rather than understanding the root cause.
Generic advice rarely works for complex gut issues because the gut is highly individual. What drives bloating in one person is completely different from what drives it in another. A personalised, evidence-informed approach - one that actually looks at the big picture - tends to produce results where generic programs haven't.
If you're feeling sceptical but curious, the free Discovery Call exists exactly for that: a chance to talk it through with no pressure.
How do I get started with The Foodie Nutritionist?
The easiest first step is booking a free Discovery Call.
It's a no-obligation 20 minute conversation where you can share what's been going on with your health, ask any questions, and get a feel for whether working together is the right fit.
There's no pressure and no commitment required.
If you're ready to go straight into a consultation, you can book an Initial Nutrition Consultation directly. Either way, the booking process is simple and done entirely from here.
