I also specialize in relieving the symptoms associated with GI conditions such as IBS and IBD.
My ideal client is someone who is looking to improve their overall health and well-being with sustainable and realistic changes to their eating patterns. Most of my clients are surprised to discover that the dieting behaviors they have participated in (e.g. restricting calories/macros or avoiding food groups) are actually more harmful to their health than health promoting. I teach my clients how to eat in a way that works best for their individual needs and preferences, remove the guilt associated with eating certain foods, and help them feel confident in their food choices.

Gastrointestinal (GI) Nutritionists and Dietitians
What is gut health?
Gut health refers to the overall functioning and well-being of the gastrointestinal (GI) system. Key to gut health is the gut microbiome, which is the collection of healthy bacteria living in the gut. These bacteria are essential for the digestion and breakdown of food, and their health significantly impacts digestion. Poor gut health can result in symptoms such as bloating, gas, diarrhea, constipation, and general abdominal discomfort, which may indicate imbalances or issues with the gut microbiome.

Can diet help with GI issues?
Diet plays a major role in gut health, and changes in diet can often reduce or eliminate some of the symptoms associated with gastrointestinal (GI) issues. Often, GI distress is due to food intolerances or sensitivities, such as gluten sensitivity or lactose intolerance. In these cases, eliminating the problematic foods from the diet can resolve the issue. GI problems can also stem from a combination of environmental or genetic factors, such as in the case of irritable bowel syndrome (IBS). Disruptions in the gut microbiome, such as those caused by taking antibiotics, can also lead to GI issues. In both scenarios, maintaining a balanced diet as much as possible with foods that support a healthy microbiome—such as fruits, vegetables, whole grains, and probiotic foods—can often significantly reduce symptoms and improve gut health.

What are the best foods for gut health?
Maintaining a balanced microbiome is essential for gut health, and this is best achieved through a varied diet rich in fruits, vegetables, and probiotic foods. Fruits and vegetables provide essential nutrients and fiber, which nourish the beneficial bacteria in the gut. Probiotic foods, which are those that contain live bacteria, are also great for gut health. Consuming probiotic foods and drinks, such as yogurt, kefir, kombucha, and tempeh, can help support the microbiome by contributing to the diversity of bacteria within the gut.

When should I see a dietitian for GI issues?
Many people can benefit from seeing a dietitian for GI issues. In general, most dietitians are knowledgeable about what foods support gut health and may help clients choose foods that support a healthy GI system, such as fruits and vegetables high in fiber or foods high in probiotics. Dietitians may be especially beneficial to clients with known gastrointestinal concerns, such as irritable bowel syndrome (IBS) or gastroesophageal reflux disease (GERD). For clients diagnosed with these or similar conditions, dietitians can help clients identify food triggers and develop a meal plan for the client that minimizes symptoms. Dietitians may also work with clients who are having gastrointestinal distress (such as bloating, gas, constipation, diarrhea, etc.) but are not aware of the cause of their symptoms. In such cases, dietitians may be able to help the client identify the cause of the GI distress and coordinate with other medical professionals to help the client better manage their symptoms.
