Member of Dr. Oz's medical advisory board says he no longer associates with the celebrity physician because of his politics: 'I want nothing to do with him'

• A member of Dr. Oz's advisory board is no longer friends with the doctor because of his politics.

• Fuhrman has appeared on "The Dr. Oz Show" five times.

• Fuhrman said that he couldn't be ethical and reasonable and be a Trump supporter.

A celebrity diet doctor who served on the medical advisory board of "The Dr. Oz Show" said he can no longer support Mehmet Oz due to his ties to former President Donald Trump.

Fuhrman knew that Dr. Oz was a doctor for a long time. I don't want to work with him now that he's a Republican.

The party's denial of climate change and Trump's attempt to "take over" the 2020 election were cited by Fuhrman as his primary concerns.

Oz is a republican from Pennsylvania who is running for a seat in the Senate. In April, Trump supported Oz.

Fuhrman is not allowed to vote for Oz in the upcoming election because he feels strongly about the political stances Oz has adopted.

Fuhrman said that he's no longer a Dr. Oz supporter because his political views are against what Trump stands for and what Oz has taken on politically. I haven't been in touch with him.

The medical board from Oz's show has come under fire for promoting questionable science such as lining one's nose with petroleum jelly to avoid viruses and drinking tea made of onion juice and lemon to treat flu symptoms.

Fuhrman told Insider he had no specific duties while serving on the board, but knew Oz from their time at the University of Pennsylvania, and at one time considered the doctor-turned-politician his friend. Fuhrman appeared on Oz's show at least five times.

One pound of raw vegetables and one pound of cooked vegetables is what the nutritarian diet requires. Carolyn Williams referred to Fuhrman's nutritarian meal plan as a "fad diet" that takes the concept of nutrition to an extreme.

Fuhrman claimed in an interview with Men's Journal that he fasted for 46 days to cure an injury to his foot.

Fuhrman doesn't support Oz because of any concerns about conflicts of interest or the science presented on his show, but he does support his diet and its ability to heal people from all manner of ailments.

Fuhrman said that he can't imagine a person to be ethical and reasonable. I don't know how it happens.

Oz representatives did not reply to Insider's questions.
