In Alvin Powell's
interview, his goal was to try and find out more about the life of Walter Willet and how he became interested in being a food and nutrition specialist. He was able to do this by interviewing him about his life in chronological order.
Starting out with his childhood, Willet describes growing up around animals. His grandfather was a dairy farmer and his father "was a Ph.D. reproduction physiologist and worked at the American Foundation for the Study of Genetics" (Powell). He grew up in Madison, Wisconsin on a research farm. He then goes on to explain how he went to Michigan State to pursue a study in physics. He then goes to Michigan to get his M.D.
Later on, his interest in food and nutrition started to take effect. He and his friends began to be involved in nutritional experiments at a local hospital. During his college days, he decided to spend some time studying abroad in Tanzania where he was also able to teach about nutrition while at the same time learning about diseases such as diabetes and cancer and their connections to ones diet.
After conducting several health studies he was able to publish his work in the New England Journal of Medicine explaining an analysis that "[showed] that with just moderate diet and lifestyle we could prevent about 80 percent of heart disease, and in another paper, 90 percent of type 2 diabetes" (Powell).
In the end of the interview, Willet explains that his life would have never been that same if he never got the chance to participate in the health and nutrition study program as a student.
