Dr. Mehmet Oz discussed the tragic death of Princess Diana, and offered his theories for why she died on the April 10 episode of the Dr. Oz Show. “We are re-examining one of the most intriguing deaths of our time,” said Dr. Oz. “She was awake and talking after her crash but was dead only a few hours later.”

Princess Diana died in August 1997 at the age of 36 after a horrific car accident in Paris. An investigation later revealed that the car Diana was riding in hit a pillar in a highway tunnel while moving at 65 miles per hour. Both the driver of the car and Diana’s boyfriend, Dodi Fayed, died instantly.

Dr. Oz was shocked to learn that Diana had initially survived the crash and wanted to understand why she later died. Dr. Oz’s guest was medical examiner Dr. Bill Manion, a forensic pathologist. Dr. Manion said when emergency workers responded to the scene of the accident, they were surprised to find that Diana was conscious and crying out for help.

Pathologist: Diana Did Not Have to Die

Diana had multiple cuts on her neck and forehead and her arm was dislocated, but she was still alive. Dr. Oz and Dr. Manion used a mannequin to re-enact the crash, and concluded that Diana likely suffered severe internal injuries after being thrown around inside the car. Exacerbating her injuries was the fact that the princess had not worn a seat belt.

Dr. Manion was outraged that it took two hours to transfer the injured Diana to the hospital, and said this inexcusable delay was partly responsible for her death. Manion said Diana’s injuries were survivable, and blamed incompetence on the part of the French medical team that tended to her injuries for her death. Dr. Manion said in his opinion, Diana would probably still be alive today had she had this accident in the United States instead of France.

Princess Diana’s tragic death has spawned countless conspiracy theories and calls for re-investigation. Some of the most bizarre theories are detailed in the book Princess Diana: The Hidden Evidence.

The O Diet was originally created for children with food allergies, but is now being used by adults as an inflammation-fighting diet to treat gastrointestinal conditions, migraines, asthma, ADHD, and eczema.

Dr. Raj, the author of What the Yuck?, said the O Diet is extreme but effective because it eliminates many different foods that trigger inflammation. The foods you should eliminate include:

  • wheat
  • fruit
  • fish
  • chicken
  • eggs
  • peanuts
  • chocolate.
