Simple, nourishing, and doing more for your body than you might think 🍎✨

Pairing fruit with protein is one of the easiest ways to support more stable blood glucose levels throughout the day. On its own, fruit (like apple) can cause a quicker rise in blood sugar, but when you add a protein source like cottage cheese, you help slow digestion and create a more sustained energy release.

Then we have cinnamon 🤍
This warming spice isn’t just for flavour - it’s been shown to support insulin sensitivity and help moderate blood glucose responses after eating.

This combination =
✔️ steadier energy
✔️ fewer crashes and cravings
✔️ better support for hormones and metabolism

It’s a simple shift, but these are the habits that add up.

Food, as always, is information for your body.

Save this as a reminder for your next snack

Soy has been one of the most misunderstood foods in women’s health.

For years, it’s been questioned because of its “oestrogen-like” compounds…but this is exactly where nutrition science has evolved.

Soy contains isoflavones, which are phytoestrogens.
These don’t behave like our natural oestrogen. Instead, they have a much weaker, more selective effect on oestrogen receptors, often acting in a modulating or even protective way.

In perimenopause, where hormones are fluctuating, this can be incredibly supportive.

Current research suggests that whole soy foods (like tofu, tempeh, edamame and soy milk) may:

• Reduce the frequency and severity of hot flushes
• Support heart health (especially as LDL tends to rise)
• Contribute to bone health
• Fit seamlessly into a fibre-rich, plant-focused dietary pattern

And importantly- whole soy foods are considered safe for the general population, with evidence continuing to support their role in long-term health. 💚

This is a reminder that nutrition science doesn’t stand still.
What we once feared, we now better understand.

👉 Soy isn’t something to avoid, in fact, for many women, it’s something worth including.

Think whole, minimally processed, and consistent.

⸻

🧁 Method

1. Preheat oven to 180°C and line a slice tray.
2. In a large bowl, whisk together wet ingredients.
3. In a separate bowl, combine all dry ingredients.
4. Fold dry into wet until just combined.

Holistic health, to me, means looking beyond symptoms and seeing the whole person 🌿

It’s understanding that your body isn’t separate systems working in isolation — your hormones, gut, metabolism, nervous system, and mindset are all deeply connected.

It means asking:
✨ What’s driving this, not just how do we suppress it?
✨ How is your lifestyle shaping your health?
✨ What does your body actually need to feel safe, nourished, and supported?

Holistic health is about creating sustainable habits that work in real life.

For me, it looks like:
• Using food as therapeutic medicine
• Supporting the gut microbiome for whole-body benefits
• Balancing blood sugar for energy, mood, and hormones
• Respecting the nervous system and stress load
• Personalising care — because no two bodies are the same

It’s also about empowering you to understand your body, so you can work with it instead of against it.

Because true health isn’t just the absence of symptoms —
it’s feeling energised, resilient, and at home in your body.

Doing all the right things… but still feeling off?
It might not just be hormones — oxidative stress could be the missing piece.

When free radicals outweigh your antioxidant capacity, it can show up as fatigue, inflammation, skin changes, metabolic resistance and hormone imbalance.

✨ This is where targeted antioxidant support matters.

One I use often in clinic? Alpha-Lipoic Acid (ALA) — a powerful, whole-body antioxidant that supports blood sugar balance, inflammation, detox pathways and energy production.

For many women, this is the shift from “coping”… to actually feeling well again.

⚖️ Always individualised. Always purposeful.

💬 If something feels off, it’s worth exploring what’s happening beneath the surface.

06/04/2026

✨ What would it feel like to:
• Wake up with consistent energy
• Feel confident in your food choices
• Support your hormones, gut & metabolism properly
• Have a clear, personalised plan (not guesswork)

As a Clinical Nutritionist, I work with you to uncover what’s really going on beneath the surface — and create sustainable strategies that actually fit into your life.

💚 Personalised testing + tailored nutrition plans available
💚 Support for women’s health, gut health, energy & performance
If you’ve been thinking about it… take this as your nudge.

Vitamin D deficiency is consistently associated with increased insulin resistance, metabolic syndrome and type 2 diabetes risk.

Mechanistically, Vitamin D influences insulin secretion via pancreatic beta-cell receptors and improves insulin sensitivity in skeletal muscle. It also modulates inflammatory pathways that drive metabolic dysfunction.

Intervention trials show the greatest metabolic benefit in individuals who are deficient at baseline — suggesting correction, not mega-dosing, is key.

For women in perimenopause experiencing:
• Central weight gain
• Rising fasting glucose
• Fatigue
• Mood shifts

Checking Vitamin D status may be a simple but powerful starting point.

Sunshine is helpful.
Testing is smarter.

50 years young.

Still training.
Still learning.
Still getting stronger.

💚 Nourishing my body
💚 Moving most days
💚 Sleeping deeply
💚 Challenging myself physically

Longevity isn’t luck.
It’s built through the choices we make every day.

It’s never too late to start.

As a clinical nutritionist, I work with women navigating:
• Perimenopause
• Low energy and hormonal shifts
• Gut health challenges
• Metabolic changes

Because feeling strong at this stage of life should be the norm — not the exception.

Collagen vs Protein Powder – are they the same? 🤔

Both are popular supplements… but they serve very different purposes in the body.

✨ Protein powders (like whey or plant proteins) are considered complete proteins, meaning they contain all essential amino acids needed to support muscle repair, metabolism and satiety.

✨ Collagen peptides are rich in specific amino acids such as glycine, proline and hydroxyproline which help support skin, joints, connective tissue and gut lining.

However, collagen is not a complete protein, so it shouldn’t replace your primary protein source if your goal is muscle recovery, strength or meeting daily protein requirements.

✔️ Protein powder → best for meeting protein needs and supporting muscle
✔️ Collagen peptides → targeted support for skin, joints and connective tissue

Think of collagen as a functional add-on, not a full protein replacement.

Food first always wins – but supplements can help fill specific gaps when used intentionally. 🌿

Hey, I’m Tracy 👋
Just a heads up on a Clinical Nutritionist’s qualifications and holistic practice methods (in case you wondered what I do vs Dieticians vs general nutrition consulting) 💚

🌈 Eat the Rainbow – Especially in Perimenopause

This isn’t just a pretty salad… it’s hormone and gut support on a plate.

During perimenopause, fluctuating oestrogen impacts:
• Blood sugar stability
• Gut motility
• Histamine response
• Mood + energy
• Inflammation levels

And one of the most powerful (and underrated) tools?
Colourful plant diversity.

Each colour represents different polyphenols and phytonutrients that:

✨ Support the estrobolome (your gut bacteria that metabolise oestrogen)
✨ Feed beneficial microbes with diverse fibres
✨ Reduce oxidative stress
✨ Support liver detoxification pathways
✨ Calm inflammation

Think:
🔴 Lycopene (tomatoes, capsicum)
🟠 Beta-carotene (carrots, pumpkin)
🟢 Sulforaphane (cruciferous veg)
🟣 Anthocyanins (red cabbage, berries)
⚪ Prebiotic fibres (onion, garlic, leeks)

Perimenopause isn’t a time to eat less.
It’s a time to nourish smarter.

More colour = more diversity = more resilience.

Your hormones love a rainbow. 🌈
