Oral microbiome, don’t overlook this heavy influencer on gut health & general wellbeing
Tracy Cowley highlights why oral health is a critical and often overlooked as a part of our whole-body and gut health.
Tracy explains how the oral microbiome directly influences digestion, inflammation, and even cardiovascular health, noting that up to 70% of New Zealanders experience some level of gum disease.
She unpacks how bacteria from the mouth are swallowed daily, potentially undermining gut healing if oral health isn’t addressed. Tracy also shares practical, reassuring advice around flossing, brushing, bleeding gums, and mineral depletion, particularly for women post-pregnancy.

Why Storms Can Trigger Headaches, Bloating & Stress
If you feel “off” when it’s windy, you’re not imagining it. Tracy explains that storms can directly impact the nervous system, gut health, brain function, and inflammation levels. Changes in barometric pressure, noise, and light can trigger cortisol spikes, activating the primal part of the brain that once associated storms with danger.
A drop in pressure may contribute to bloating, blood vessel dilation, and even inflammation of the meninges, helping explain storm-related migraines and headaches.
Got a headache after a blustery day? Be gentle on yourself. Focus on lowering cortisol with simple stress-management tools: gentle exercise, warming foods like soups, and humming to stimulate the vagus nerve and shift from fight-or-flight into rest-and-digest mode.
Bad weather may just be doing more than giving you frizzy hair.

The Truth About Weight Loss for Women: Why Eating Less Isn’t the Answer
Weight loss is one of the most commonly ‘Googled’ health topics right now and Tracy is seeing more women than ever asking for help. Many initially come in to her clinic for gut issues, poor sleep, post-baby weight, or perimenopause changes, but weight loss quickly becomes part of the conversation.
With the rise of GLP-1 medications like Ozempic and Wegovy, appetite suppression is being normalised, yet Tracy is increasingly concerned about malnutrition, muscle loss, osteoporosis, hair thinning, and long-term metabolic damage associated with these medications.
For women, simply eating less can backfire. Calorie restriction slows metabolism, increases fatigue, disrupts hormones, and often leads to rebound weight gain.
Instead, Tracy focuses on sustainable weight loss and body/mind strength through adequate protein (especially before 10am), fibre, blood sugar balance, and most importantly, body positivity.

Autumn Immunity Reset: Strengthen Your Gut, Stress Less & Stay Well This Winter
Tracy shares practical strategies to strengthen immunity as autumn approaches.

Tracy also highlights the importance of seasonal eating, encouraging a shift from cold smoothies and salads to warmer, gut-friendly meals that support digestion.
A key focus is building a diverse gut microbiome by aiming for 30 different plant foods per week, including vegetables, fruits, nuts, seeds, legumes, herbs, and spices.
By improving gut health and reducing stress, Tracy outlines simple, evidence-informed steps to support immune resilience and avoid recurring colds and fatigue through winter.
