Who we are

  • Barbara Olendzki

    Barbara Olendzki, RD, MPH, LDN

    Director of the Center for Applied Nutrition; Associate Professor of Medicine Umass Chan Medical School, Creator of the IBD-AID therapeutic dietary pattern

    I have been fortunate to be at the forefront of a quiet revolution within medicine: to change the course of chronic, often deleterious diseases through food and nutrition. My favorite accomplishments have integrated my nutrition research into clinical practice and education that provides foundations for our future.  I have seen people truly heal through modification of dietary patterns that preserve culture, tradition, family and community.  We celebrate and grieve with food; we live to eat and eat to live.  Culinary Medicine is the way of the future, when physicians will write as many prescriptions for healthy and tasty dietary patterns as we do for now for medication.

    Ana is a clinical translational researcher intersted in understanding the interaction of diet, the microbiota, and disease. Our bodies are home of trillion of bacteria, namely the microbiota. The microbiota provides tremendously benefits, from protecting us for malicious bacteria (pathogens) to help in training our immune system so it can respond properly. An unbalanced microbiota is associated with diseases such as diabetes, obesity, and inflammatory bowel disease. Ana's lab investigates how manipulation of the microbiota through diet can benefit patient outcomes, particularly those suffering from inflammatory bowel diseases.
