With my own history of gut problems and sensitivities, I have learned how complex the relationship between our food, our mind and our lifestyle factors play a role in our gut health and simultaneously interact.

Digestive health is a primary focus area of my practice, as I recognize from personal experience as well as working with 100s of clients that optimal digestive health is essential for every aspect of our wellness such as our mental health, immunity, exercise recovery and performance, hormonal health, and more.

As a Digestive Health Dietitian, I am also trained by MONASH University in the low FODMAP diet and specialize in supporting those with IBS utilize the low FODMAP diet to find symptom relief.

Favorite Low FODMAP Diet Tip

Diversity is crucial for a healthy gut-microbiome, which is essential for efficient digestion and managing IBS. When following a low FODMAP diet, avoid the common path of falling into having the same ‘safe’ fruits and vegetables every day. Be sure to seek out resources to help you add more variety of plant foods to your diet, and work with a Dietitian if you are struggling.

Favorite Low FODMAP Recipe

I absolutely love nourish bowls (aka buddha bowls) because they are a great way to get in lots of colours and plant variety. For a low FODMAP option, I combine a whole grain (quinoa, brown rice), plant protein (firm tofu or tempeh), raw veggies (like purple cabbage, carrot, cucumber, spinach), and a dressing. A great example I love is the Banh Mi Tofu bowl.
