Walter Willett

Walter Willett has been interested in food, food processing, and nutrition his entire life. He went to medical school. Willett's family is involved in agriculture, which led him to become interested in the area. Willett conducted experiments to further his knowledge of nutrition and what food does to people's health. Willett taught public health in Tanzania to better inform the people of their nutrition. He found that breast cancer and cataracts are largely related to diet and nutrition. He was the first to administer any type of dietary questionnaires. Willett chose to do research rather than pursue an internal medicine career, because he wanted to be able to prevent or delay the onset of incurable conditions. Willett would like to know more about Alzheimer's and Parkinson's disease, so he's conducting research on both conditions. The main issue of concern is being able to feed the whole population healthy food. The environment needs to be taken care of first so "healthy food can be produced in a sustainable way" for humans.
