Scientific process vs. nutrition and lifestyle advice

Background: I sometimes receive better health and fitness recommendations from friends. I find it very difficult to categorise expert from non-expert sources. The documents frequently cite newspapers or TV shows which, whilst respectable, might not submit their content to as much 3rd party analysis and checking as a normal paper or book publication process. How does one quickly figure out what to pay attention to and what to ignore?

Part of the source of the problem was a proliferation of self-proclaimed "universities" offering mail-order "degrees" late last century. I recall even Australia had one external territory in which a scam university temporarily operated. We're now seeing the fruits of these shonky graduations!


While attempting to more quickly identify unreliable sources in nutrition, diet, exercise, etc. or unusual "universities" that might be a common cause, I discovered a number of groups attempting to do the same thing. My current list of relevant information (early 2014):

People of interest:
  • Deepak Chopra is described in http://www.skepdic.com/chopra.html as "a graduate of the All India Institute of Medical Sciences (1968) and a former leader of the Maharishi Mahesh Yogi's Transcendental Meditation and Ayurvedic medicine  programs". He seems to know about meditation but has swallowed and now emits some strange pseudo-science interpretations of quantum physics (which he seems to connect to meditation). He also sells ideas on healthy living.
No doubt this list can grow...
