Dr. Mehmet Oz recently extended his brand of medical advise to the New York Police Department, serving as a guest lecturer for a department training session.

The celebrity TV doctor spoke to over 150 detectives last week about taking better care of themselves. His advice included proper dieting, getting a good night’s sleep and other routine medical tips.

He recommended eating “food that you love that happens to be good for you” and sleeping in a cool room for seven-and-a-half hours a day, according to the New York Post.

One veteran cop called Oz’s lecture “highly unusual” and slightly tone deaf.

“He talked about taking care of yourself, eating properly, good-diet tips, high cholesterol, getting a good night’s sleep — as if that’s possible for a New York City detective,” the cop added.

Oz said the increasing health problems among officers prompted him to offer his expertise.

“A bunch of detectives have literally dropped dead on the job from diseases they could have prevented,” he said by phone from Washington, DC, where he attended the UNITE to Face Addiction concert rally.
