Query: WARNING This book may be dangerous for allergic people

While the intentions of this book may be sincerely well meant, this book could be extremely dangerous to those with sensitive allergies. Many of the products are cross-contaminated and could be very dangerous to allergic people. My son has reacted to some of her recommendations due to the cross-contaminations. The book should of been reviewed in detail for medical accuracy since allergies can be life threatening. With all of the confusion due to the differing severity of allergic reactions this book misleads as to the safety of these products and recipes.
