Unfortunately you gotta do your own research and not just turn to a doctor for health advice at least in my opinion.
So would you trust someone receiving tons of money from corporations to do unbiased research? I wouldn't and don't. Sadly, this is why I don't trust financial advisors and medical doctors when it comes to them giving advice.
I say sadly, as health and finance are two very very very important to our well being - health and money. I would say most people want to be healthy, especially if they are sick. Who wants to be poor? Who doesn't want good financial advice or good unbiased advice at least when asking for advice.
Something to think about next time you go to the doctor.
