Dr. Johnson studies the relationship between diet and the microbiome. She holds a Ph.D. in Nutrition from the University of Minnesota and devotes much of her time to research. Since 2010, Dr. Johnson has been heavily interested in gut issues and the microbiome. While studying in Chicago, she learned a great deal about fats in the gut, bowel disorders, and more, and her interest was triggered. She states that what we eat can literally change the bacteria in our guts. She talks about the foods we eat and the many microbes that are within. Her research begs the questions: can we change the stability of the microbiome?
