In The Peanut Allergy Epidemic, Fraser delves into the history of this allergy, trying to understand why it largely develops in children and studying its relationship with social, medical, political, and economic factors. In an international overview of the subject, she compares the epidemic in the United States to sixteen other geographical locations, finding that in addition to the United States, in countries such as Canada, the UK, Australia, and Sweden there is a one in fifty chance that a child, especially a male, will develop a peanut allergy. Fraser also highlights alternative medicines and explores issues of vaccine safety and other food allergies, making his book a must-read for every parent, teacher, and health professional.
