I work virtually with motivated individuals or couples (in Ontario) who are actively trying to conceive or planning for pregnancy. They seek evidence-based information and personalized guidance to optimize their fertility and prenatal nutrition. With concerns about their current diet, lifestyle choices, or specific medical conditions, they are driven to provide the best start for their future child. They value the role of nutrition in this process and are open to making positive changes. Ultimately, their goal is to create a healthy, nurturing environment for their little one to thrive.

Coming from a multicultural background and being an immigrant to Canada, I bring a unique perspective that recognizes and respects various dietary practices and cultural food traditions.

Whether you are seeking a dietitian for preventative reasons, digestive issues, beginning a new chapter in life (pregnancy, introducing to solids, picky eaters), or need support with a new diagnosis ( PCOS, Endometrosis, Thyroid Disease etc.) I am here to support you!
As a registered dietitian I take an anti-diet approach to support my clients. Growing up as a "picky eater", I was always told how to eat and how much to eat. As I got older, I grew an interest for food and nutrition which led me to become a registered dietitian. Now I support individuals in creating sustainable dietary changes based on their preferences, dietary restrictions and medical history. I believe that embracing cultural foods, enjoying all foods and meeting your nutrition needs can all be done in sync. I specialize in pediatrics, women's health and family nutrition.

Polycystic Ovarian Syndrome (PCOS) Nutritionists and Dietitians
What is Polycystic ovarian syndrome (PCOS)?
Polycystic ovarian syndrome (PCOS) is a condition characterized by hormonal imbalance, leading to symptoms such as irregular or absent periods, weight gain, excess hair growth, infertility, and acne. The exact causes of PCOS are not well understood, but it is believed to result from a combination of genetic and lifestyle factors, including stress and nutrition.

How is PCOS treated?
PCOS is typically treated with a combination of medication and lifestyle changes. Many individuals with PCOS are prescribed birth control medication to help regulate the abnormal hormone levels associated with the condition. With regard to lifestyle modifications, healthcare professionals often recommend maintaining a balanced, healthy diet and engaging in regular physical activity. This is particularly important for women diagnosed with obesity or diabetes, as weight loss and improved insulin regulation can significantly alleviate PCOS symptoms.

What diet is best for people with PCOS?
In general, experts recommend a plant-based diet high in fiber, healthy fats, and lean protein as the best nutritional approach to managing PCOS. Because women diagnosed with PCOS are at a higher risk of specific conditions, such as type 2 diabetes, hypertension, and heart problems, a diet that helps prevent such conditions can be highly effective. The "Mediterranean diet," characterized by the consumption of lots of healthy fats, vegetables, beans, and whole grains is one common diet with evidence supporting its efficacy in preventing cardiovascular and metabolic diseases. In addition, other lifestyle modifications that support weight management and healthy insulin levels—such as exercise, smoking cessation, and alcohol consumption reduction—are often also incorporated into PCOS treatment.

What foods should people with PCOS avoid?
Due to the high blood sugar levels and insulin resistance characteristic of PCOS, experts typically advise individuals with PCOS to avoid foods that cause large blood sugar spikes, such as sugary snacks and refined carbs like white bread. Instead, they recommend consuming foods rich in healthy fats, whole grains, and fiber, which can help stabilize blood sugar levels. Individuals with PCOS may also find that certain foods trigger their symptoms. Therefore, identifying and avoiding these specific foods can be important for reducing symptom severity on an individual level.
