Eating with IBD: The Essentials” is now available!

“With the right knowledge and resources, you still can enjoy all that food has to offer.”
Colleen Webb

My mission is to improve your quality of life by empowering you to use food and nutrition to manage your digestive health.

Every day we make decisions about what to eat. Many factors influence our food choices, including family, culture, time, money, knowledge and health. Choosing what to eat can be very challenging for people with gastrointestinal troubles. I specialize in providing personalized nutrition counseling to people with the following conditions:

  • Inflammatory Bowel Disease (IBD)
  • Crohn's disease
  • Ulcerative colitis
  • Microscopic colitis
  • Irritable Bowel Syndrome (IBS)
  • Food intolerances
  • Food sensitivities
  • Small intestinal bacterial overgrowth
  • GERD
  • Bloating
  • Abdominal pain / discomfort
  • Other digestive conditions

Healthy eating is important, but enjoying food is paramount.

In 2011, my husband and I began discussing starting a family. Unfortunately, I have ulcerative colitis and was on Asacol. While doctors told me it was OK to be on a small dose of the medication while pregnant, I did not want to take any chances. I therefore decided that I wanted to get off the medication and figured that a healthy diet could be the best way to accomplish this. I met with Colleen who was extremely thorough in going through my food diary and explaining what I was eating that was hurting me and what I was missing. She was patient and understanding and I was confident that she understood my disease and how to help me get healthy sans medication. I followed her advice and had a healthy baby girl in 2013. Maintaining the diet allowed me to experience the most beautiful miracle without controllable risk and, to this day, maintain a healthy lifestyle free of medicine.

If you’re suffering from Inflammatory Bowel Disease (IBD), then you likely have a lot of questions about food.

A few of the ones I hear most often...

I’ve heard that what I eat with IBD doesn’t matter, is that true?

No, not true! We don’t know at this time whether or not food causes, prevents or cures IBD, but we do know that what you eat plays an important role in managing your disease. I use food and nutrition to help you feel your best, to help your medications work more effectively, to correct or prevent nutrient deficiencies, and to better control your symptoms.

Is there one diet for people with IBD?

No, there is not one diet for everyone with IBD, just like there is not one medication for everyone with IBD. I work closely with you to develop a personalized nutrition plan that takes into account your past medical history, food preferences, food triggers, disease activity, etc.

How does my disease activity impact what I can eat?

What you eat during a flare can be very different from what you eat when you’re in remission. For example, many people need to avoid high fiber foods during flares but not when they’re healthy. Part of my job is to educate you on how to modify your diet based on your disease activity while ensuring that you’re eating a healthy diet at every stage.

Colleen has skillfully guided me through the resolution of multiple severe digestive problems including small intestine bacterial overgrowth (SIBO), fructose intolerance and multiple food intolerances and allergies. I have been very grateful for her help and I highly recommend her.

Food Sensitivities

Are you tired of guessing what foods are making you sick? Do you wish that there was a better way of identifying food triggers besides food diaries?

You’re in luck.

Mediator Release Testing (MRT) is the best blood test for food and food-chemical sensitivities. Food and food-chemical sensitivities are highly complex non-allergic inflammatory reactions that are very challenging to identify and manage on their own.

I will combine your MRT results with my clinical experience to design a patient-specific anti-inflammatory eating plan to help you live a healthier and happier life.

Prior to the mediator release test, my digestive issues seemed to be completely irrational and I was unable to pinpoint what my triggers were. The MRT was able to take out most of the guessing, allowing me to complete a LEAP diet in which I recorded all digestive responses and re-learned my body. Though it was a long process, my gut was given the proper time to heal and I have now gained the strength to live my life normally.
