Headshot of Colleen WebbMeet Colleen

I’m a registered dietitian nutritionist with years of experience counseling patients with complicated gastrointestinal issues, including Crohn’s disease, ulcerative colitis, and IBS. My fascination with nutrition and gut health began in 2011 when I started working at the inflammatory bowel disease center at Weill Cornell Medicine in NYC. That’s where I discovered that a strong gut is essential for optimal health.

My mission is to improve lives by empowering people to use food to improve their digestive health. I do this through counseling patients in my private practice, teaching graduate students at NYU, instructing medical students at Weill Cornell Medical School, blogging, lecturing nationwide, and creating tools for patients and health care providers as co-founder of Wellness By Food. Wellness by food is a nutrition and lifestyle resource for people with inflammatory bowel disease.

My professional experience has made me a go-to authority for physicians, patients, and other dietitians seeking answers to their gut-related questions.

I’m psyched to be part of the FODMAP Everyday Success Team because I’ve helped countless individuals successfully change their lives for the better using the low FODMAP diet. I love how FODMAP Everyday shows patients how delicious low FODMAP food can taste.

In my free time, I love spending time with my family exploring NYC, traveling, cooking, and snuggling with my baby boy.

My Favorite Low FODMAP Recipe Header

FODMAP Everyday’s Vegetable Latkes. I’m a sucker for potato latkes and now that I have a food processor, I can grate potatoes in no-time. This recipe satisfies my latke craving while using up leftover veggies and boosting total nutrient content.
