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.

My ideal clients are parents of young and teen athletes trying to keep up with the growing demands of sport, school, and daily life. They often feel unsure what their child actually needs and notices things like inconsistent energy during practices or games, slower recovery, changes in appetite, or just a general sense that nutrition isn’t keeping up with training and growth. Together, we take a step back and look at the full picture , your child’s schedule, training demands, eating patterns, and daily routine. From there, we create a simple, realistic plan that supports energy, performance and recovery without adding stress.

Crohn's Nutritionists and Dietitians
What is Crohn's disease?
Crohn's disease is a type of inflammatory bowel disease (IBD) characterized by inflammation in the intestines. It is considered an autoimmune condition, where the immune system becomes overactive in the lining of the digestive tract, causing symptoms such as abdominal pain, cramping, bloating, and the presence of blood or mucus in the stool. People with Crohn's disease can experience complications like infections and malnutrition and have an increased risk of colorectal cancer. Unfortunately, there are few definitive treatments for Crohn's disease. However, some patients are prescribed immunosuppressant drugs or steroids, which reduce the immune response and can help reduce symptoms of the disease.

Can Crohn's disease be cured with proper nutrition?
There is little evidence to suggest that Crohn's disease can be cured through nutrition. However, certain foods may worsen symptoms or trigger flare-ups. Common examples include dairy products, high-fat foods, processed meats, high-fiber foods, and beverages containing alcohol or sugar alcohol. People with Crohn's disease are generally advised to avoid foods that exacerbate their symptoms and to focus on consuming regular meals with adequate protein and nutrient density to prevent malnutrition.

What can you eat if you have Crohn's disease?
With the exception of avoiding foods that may exacerbate symptoms, individuals with Crohn's disease are often advised to consume a normal diet. Since Crohn's disease is an autoimmune condition and not caused by specific foods, it is generally recommended that individuals eat a regular and balanced diet as much as they can tolerate.

Should people with Crohn's disease see a dietitian?
People with Crohn's disease are at a greater risk of malnutrition and weight loss, as well as nutrient deficiencies, due to the poor absorption within the digestive track that can occur as a result of the disease. Therefore, dietitians can be highly beneficial to people with Crohn's disease to minimize the potential effects of malnutrition and ensure daily nutrient needs are being met. They may help people with Crohn's disease identify foods that contain sufficient calories and nutrients but minimize symptoms, such as suggesting iron-rich foods for clients with anemia. People with Crohn's disease also often experience flare-ups followed by periods of relief, so dietitians may be helpful in assisting clients in identifying food or nutrition-related factors that may contribute to or worsen their flare-ups.
