Answer: Harvey Wiley, a chemist and food safety advocate, conducted experiments in the late 19th and early 20th centuries to demonstrate the harmful effects of certain chemicals commonly added to food. He recruited a group of young men to participate in a study, where they were fed small amounts of these chemicals over a period of several months. The results of the experiment showed that the chemicals caused adverse health effects, such as nausea, headaches, and depression.
Wiley's experiments were influential in raising awareness about the dangers of food additives and led to the creation of the Pure Food and Drug Act of 1906, which established the Food and Drug Administration (FDA) and regulated the production and sale of food and drugs in the United States. The results of Wiley's experiments helped to pave the way for modern food safety regulations and demonstrate the importance of scientific research in protecting public health.
