There are certainly some benefits to having medical/health shows. They open up the opportunity for people to become informed about their health and potentially bring issues up with their own doctor that they may not have otherwise done.
Allow me to explain: TV is a very competitive industry. If you are going to survive you have to remain interesting and fast paced at all times to maintain the attention span of the average viewer. The problem is that you cannot give sound medical advice in that kind of environment.
Humans are complicated. Nutrition is complicated. Living a healthy life CAN be and usually IS complicated. If it wasn't, I'd probably be working as a chef or making a sad attempt at getting into musical theater.
I remember when Dr. Oz first came on TV. His information was pretty generic but it came from a sound medical background. Over the years though, I have watched a once sharp minded cardiologist go from what he knows to acting like he knows everything. Not only that, but the information he uses now isn't always from sound sources.
A couple of times I've turned on the TV and he's invited some 'expert' that is promoting a product with no scientific evidence and to top it off has been sued before for malpractice or misleading advertising. I have said in the past there are alternative health professionals I respect and trust, but the quality of people brought on Dr. Oz is definitely questionable at times.
Yet people trust Dr. Oz and they trust the Drs because they appear reputable. Why wouldn't they be? They wear a lab coat all the time and have a nationally popular TV show. TV producers wouldn't dream of putting information on TV that is incorrect or misleading just because it's interesting right.....right?
All I ask is that you be careful when taking in the information these doctors put out there. They've only got a few minutes between commercial segments to give you their interesting point of view. Often the topic in exaggerated to make it more interesting and some information may be missing due to time and interest sake. If you learn something from one of these doctors, go speak to your own doctor or health professional.
Doctors, dietitians and nurses are required by law to give the most up to date, sound advice on topics they can. That's the other reason I'm baffled by these shows though. How can Dr. Oz still have a license to practice with all the poorly researched garbage he's putting out on the air?
