Passionfruit: Small fruit, big benefits

/in , ,

Wrinkled on the outside, vibrant and jewel-like inside, passionfruit is one of New Zealand’s most distinctive summer fruits.

Beyond its distinctive aroma and tangy sweetness, passionfruit offers impressive nutritional benefits, supporting digestion, immunity, heart health and even mood. Small but mighty, this fruit earns its place as more than just a decorative topping, as Paula Sharp elaborates.

Growing passionfruit

Grown widely across warmer regions, particularly in home gardens and organic orchards, passionfruit thrives with minimal intervention when conditions are right, making it a natural fit for organic growing systems. You can grow it from seed, generally from October to May.

Passionfruit (Passiflora edulis) likes moist, fertile soil and a warm, sunny and sheltered spot.

A framework, such as wires or trellis, is essential for the vine to to climb up. It can be grown alongside a fence, with wires, or even in a tub, with bamboo stakes or tub trellis.

A nutrient-dense favourite

Passionfruit is rich in vitamins, minerals and plant compounds that support whole-body health. Just one fruit contains a meaningful amount of vitamin C, essential for immune function, skin health and collagen production. Vitamin A and carotenoids contribute to eye health and cellular repair, while potassium supports healthy blood pressure and heart rhythm.

Focus on fibre

What truly sets passionfruit apart is its fibre content. The edible seeds and pulp provide both soluble and insoluble fibre, supporting digestive health, bowel regularity and beneficial gut bacteria. For those focusing on blood sugar balance, fibre helps slow the absorption of natural sugars, making passionfruit a smart addition to meals rather than a spike-and-crash snack.

Gut health and digestion

Traditionally passionfruit is used in herbal medicine systems for its calming properties, but modern nutrition also highlights its role in digestive wellbeing. The fibre feeds beneficial gut microbes and supports healthy gut motility, the coordinated muscular contractions that move food efficiently through the digestive tract.

The polyphenols in passionfruit act as antioxidants, helping to reduce inflammation in the digestive tract. In organic systems, where soil health is prioritised, fruits like passionfruit often show higher polyphenol content. Healthy soils produce resilient plants, and that resilience is reflected in their nutritional profile.

Heart and metabolic support

Passionfruit contains potassium, magnesium and plant sterols that collectively support cardiovascular health. Fibre plays a role in lowering LDL cholesterol, while antioxidants help protect blood vessels from oxidative stress.

For those managing insulin resistance or aiming for metabolic balance, passionfruit works best paired with protein or healthy fats, for example alongside yoghurt, nuts or seeds to further stabilise blood sugar levels.

A gentle mood booster

Interestingly, compounds found in the passionflower family have been studied for their calming effects on the nervous system. While the fruit itself is milder than medicinal extracts, its magnesium content and antioxidant profile can support stress resilience as part of a balanced diet. The sensory experience alone, that tropical aroma and burst of flavour, often brings a moment of joy, which is no small thing in today’s busy world.

Choosing and using passionfruit

Ripe passionfruit should feel heavy for their size with wrinkled skin – smooth skins usually indicate under ripeness. Organically grown fruit may show more surface imperfections, but inside, the pulp remains vibrant and nutrient-rich.

Passionfruit requires little preparation: simply halve, scoop and eat. The seeds are entirely edible and contribute much of the fibre and beneficial fats.

Passionflower Tea

The fruit offers vibrant nutrition, but also the leaves and flowers of the passion vine, particularly species such as Passiflora incarnata. This is traditionally drunk as a herbal tea (or herbal tincture) because of its renowned calming properties.

Passionflower tea is useful when you are feeling: mild anxiety and nervous tension, restless sleep, and/or stress-related digestive discomfort.

The plant contains flavonoids and alkaloids thought to gently influence GABA receptors in the brain. These promote relaxation without heavy sedation. It’s often used as part of a bedtime routine or during heightened stress.

NB. While considered safe, it’s not recommended during pregnancy, and anyone on sedative medication should seek professional guidance before use.

How to make passionflower tea

  1. Place 1 teaspoon dried organic passionflower (leaf and flower) in a teapot or infuser. Pour over a cup of ‘near to’ boiling water.
  2. Cover and steep for 5–10 minutes. (The longer it’s left, the stronger the flavour and herbal properties. As a sleep aid, steep for 10 minutes or more).
  3. Strain and enjoy warm.

Ideally, for sleep support, drink 30–60 minutes before bed. For daytime calm, enjoy mid-afternoon.

The Gut Microbiome

/in ,

8 tips for whole-body health

One of the most complex systems supporting your health isn’t your brain, heart, or even your immune system – it’s your gut microbiome.

Nutritional therapist Paula Sharp finds out why this internal ecosystem, composed of trillions of microorganisms, is hailed by scientists as key to health research.

Your gut microbiome is the diverse community of bacteria, viruses, fungi, and other microbes residing primarily in your large intestine.

They are microscopic, but have an enormous collective impact. They have essential roles in digesting food, modulating inflammation, and influencing brain health.

The microbiome also builds and regulates most of our immune function.

What is the gut microbiome?

Imagine a rainforest inside your body, teeming with life. Like any ecosystem, the gut microbiome thrives on diversity and balance. This community of microorganisms works together to help you break down fibre, extract nutrients, synthesise vitamins (such as B12 and K), and produce beneficial short-chain fatty acids.

While we tend to think of bacteria as harmful, the majority living in your gut are either beneficial or neutral. These microbes co-evolved with us and perform tasks we cannot do on our own—such as fermenting non-digestible carbohydrates or keeping pathogenic (harmful) bacteria in check.

It’s estimated that the human gut contains between 300 to 1000 different species of bacteria, with every individual having a unique microbiome signature, influenced by genetics, diet, environment, and lifestyle.

The microbiome’s role in the body

Research over the past decade has dramatically changed our understanding of the gut microbiome. Once considered a passive system, it’s now seen as an active organ in its own right, interacting with nearly every physiological process.

1. Digestion and nutrient absorption

Gut microbes help break down complex carbohydrates, such as dietary fibre, that we can’t digest on our own. The fermentation of fibre by certain bacterial strains produces short-chain fatty acids (SCFAs) like acetate, propionate, and butyrate. These SCFAs are anti-inflammatory and nourish the cells lining the colon.

2. Immune system regulation

About 70% of your immune cells reside in the gut lining. A healthy microbiome helps maintain the balance between immune tolerance (not reacting to harmless substances) and defence (attacking pathogens). An imbalanced microbiome may contribute to autoimmune conditions – in which the body mistakenly attacks its own healthy cells – and chronic inflammation.

3. Gut–brain axis

The gut-brain axis describes the two-way communication between the gut and the central nervous system. Through neural, hormonal, and immunological pathways, the gut influences mental health.

Certain strains of bacteria, particularly lactobacillus and bifidobacterium produce neurotransmitters like serotonin and GABA, these improve mood and cognitive function.

However, some bacteria mimic and interfere with these neurotransmitters. E-coli, campylobacter and clostridium are some of the bacterial culprits which release inflammation causing compounds (or toxins) causing mood to dip, anxiety to increase and sleep to be compromised.

Emerging evidence even links gut health to neurodevelopmental conditions like autism spectrum disorder and degenerative diseases such as Parkinson’s disease.

What disrupts the microbiome?

Despite its resilience, the gut microbiome is highly sensitive to changes in our environment and behaviour. Modern lifestyles, particularly in industrialised nations, are often hostile to microbial diversity.

1. Dietary factors

Diets high in ultra-processed foods, added sugars, and low fibre reduce beneficial species and encourage the overgrowth of pathogenic bacteria, which are otherwise not a problem when the microbiome is balanced.

Excessive alcohol consumption and low intake of plant-based foods limit microbial diversity.

2. Medications

Antibiotics, while lifesaving, can wipe out both good and bad bacteria, potentially leading to long-term imbalance.

Medications that reduce stomach acids, NSAIDs (non-steroidal anti-inflammatory medications), and artificial sweeteners all negatively alter the gut microbiome.

3. Lifestyle stressors

Chronic stress or cortisol poisoning is felt in the gut.  The stress-hormone response increases intestinal permeability (leaky gut) and impairs microbial balance. This can show up as stress diarrhoea, nervous urination, nausea and ‘tummy ache’ in the lower abdomen. Is it just butterflies in your tummy, or compromised gut health?

Poor sleep quality disrupts the circadian rhythm of gut microbes. Sedentary behaviour has also been associated with reduced microbial diversity.

Eight ways to nurture your gut microbiome

Restoring and maintaining a healthy gut doesn’t require drastic changes. Simple, evidence-based strategies such as the following can support your microbiome’s resilience and diversity:

1. Eat a diverse range of whole foods

A variety of fibre-rich foods feeds different bacterial strains. Aim for 30+ plant types per week, including vegetables, fruits, nuts, seeds, legumes, herbs, and whole grains.

2. Prioritise prebiotics and probiotics

Prebiotics are non-digestible fibres that act as food for beneficial bacteria. Sources include garlic, onions, leeks, asparagus and bananas.

Probiotics are live bacteria found in fermented foods like yoghurt, kefir, kimchi, sauerkraut, and miso. These can help restore microbial balance, especially after antibiotic use.

3. Minimise ultra processed foods

Artificial additives, emulsifiers, and preservatives in highly processed foods harm microbial communities and contribute to metabolic dysregulation.

Ultra processed foods look like this: instant noodles, snack chips, sugary cereals, frozen chicken nuggets, processed cheese slices, fizzy drinks and snack bars.

Many of them contain MSG (monosodium glutamate), thickeners, and phosphoric acid as additives. Taste has been enhanced with lab-produced flavourings such as ‘cheese flavour’, ‘strawberry flavour’, ‘honey flavour’. And the preservatives of choice are sulphates, sodium and/or sorbates. Food labels can feel like a minefield, but if you don’t recognise what’s on the label, it can be considered ultra processed food. 

4. Stay hydrated

Water is essential for maintaining a healthy gut lining and aiding fibre fermentation.

5. Move your body

Regular exercise has been linked to increased diversity and abundance of health-promoting bacterial strains.

6. Manage your stress

Mind-body techniques such as meditation, breathwork, or gentle movement like yoga can regulate the gut-brain axis and reduce inflammation.

7. Sleep consistently

A regular sleep schedule supports the natural circadian rhythms of your gut bacteria, which influence digestion and hormone production.

8. Consider supplementation carefully

While probiotic and prebiotic supplements can be helpful, they’re not one-size-fits-all. It’s best to consult a qualified health professional to tailor recommendations to your needs.

The microbiome and the future of health

We’re just scratching the surface of microbiome science. With emerging links to conditions as diverse as type 2 diabetes, cardiovascular disease, allergies, skin conditions, and even cancer, researchers believe the microbiome may soon be a central focus for personalised and preventive medicine.

Microbiome testing and interventions may one day guide us in choosing the best foods, therapies, or even medications based on our internal microbial profile.

The gut microbiome represents a new lens through which we can understand health, illness, and healing. It’s not about striving for perfection—but rather cultivating balance.

By eating real food, managing stress, staying hydrated, and treating your gut with respect, you can positively influence not just your digestion, but your immunity, energy levels, mood, and long-term vitality.

The joys of sauerkraut

/in ,

By Mike Bradstock

Sauerkraut is one of the healthiest preserves you can make. By a natural fermentation process it converts humble cabbage into a tasty and versatile nutrient-and-vitamin-rich product. It is high in vitamins C, K, B6, folate, and minerals including iron, calcium and magnesium. The only drawback is its comparatively high salt content, though this is partly offset by less need to salt the food you eat it with, and you can remove some of the salt by rinsing immediately before use.

Many people believe sauerkraut needs to be made in bulk and is tricky and a lot of work. In fact it is easy and you can make it in small quantities; I only make only a couple of litres (about one cabbage’s worth) at a time.
