Nutrition Support for Healthy Aging and Longevity, Rooted in the Gut Microbiome
Health is complex and there is no single strategy for maintaining it,
but two areas that are non-negotiable are nutrition and gut microbiome health.
I help adults across Ontario age well through personalized, evidence-based nutrition — focusing on the gut microbiome, inflammation, and the nutrients your body and brain need to function well, now and for the rest of your life.
Rising blood sugar, cholesterol, blood pressure or triglycerides
Fatty liver disease
Low energy
Cognitive decline
Loss of bone density
Frequent illness
Some cancers
Joint issues
Poor sleep
Increasing weight
Frailty
Your gut microbiome—the community of bacteria, viruses and fungi living in your digestive system—plays an important role in several aspects of aging.
It influences:
Inflammation – a key driver of many health conditions, including diabetes, heart disease, fatty liver disease, Alzheimer's and cognitive decline, osteoporosis and joint issues
Energy production – through mitochondrial health
Immune system regulation – for healthy immune function
The body's detoxification and antioxidant systems

Unfortunately, as we age our gut microbiome's diversity typically declines, often with decreases in beneficial bacteria and increases in inflammatory bacteria.
Supporting gut microbiome health through nutrition is one way to help create a stronger foundation for healthy aging and longevity.
Gut microbiome testing allows us to see exactly where your gut microbiome needs support. In this way, your care is personalized to you.

Some reasons you may benefit from nutrition support
You're concerned about what your later years might look like for your health
Maybe you are already feeling the effects of aging
You want to prevent certain health conditions that run in your family
You have any of the following: high blood glucose, high cholesterol, high blood pressure, liver disease, osteoporosis, insomnia, overweight, declining cognitive function, mood or anxiety issues, etc.
You feel overwhelmed by conflicting nutrition advice and you want an evidence-based approach
You would prefer to reduce reliance on medications where appropriate
You want to able to live your best life, now and for decades to come
The evidence supports a whole food, plant-forward diet for healthy aging, longevity and gut microbiome health.
This it is then personalized to you and your specific health concerns and preferences.
I know firsthand that changing the way you eat can be challenging.
I work with you to make small changes over time that feel sustainable for you. Some changes are better than no changes. It remains completely up to you to what extent you adopt this way of eating.
I provide easy guides, recipes and individual recommendations reduce overwhelm and that fit your lifestyle.
Many people find this new way of eating delicious and love the way it makes them feel.


Nutrition is not a replacement for medical care.
It works best as part of a broader support system, which may include:
medication or other medical interventions
lifestyle changes
stress management
This approach is about supporting your body alongside other forms of care—not replacing them.
