Research by Department of Nutrition, Food Science, and Packaging graduate student, Cassandra Boyd, and Assistant Professor Dr. John Gieng have recently featured in Newsweek, Yahoo, Everyday Health, and many other news sources. They performed a literature review of around 70 articles, estimating the prebiotic content of 43 foods and extrapolating that data to estimate the prebiotic content of more than 8,600 foods detailed in the 2015-2016 Food and Nutrient Database for Dietary Studies (FNDDS). The foods that were found to be some of the highest in prebiotics (50 – 243 milligrams per gram food) were dandelion greens, jerusalem artichoke, garlic, leek, onions, onion rings, peas and onions, creamed onions, cowpeas, and asparagus.
Congratulations Cassandra Boyd and Dr. John Gieng on their recognition!
Correction:

A previous version of this story incorrectly listed the number of foods that were estimated for prebiotic content as 117 instead of 43.
