When it comes to personal health, I think that we tend to obsess over the concept of "normal", and the idea that if we do everything ""right", then we should live a long happy life... and... if we can do it without resorting to unnatural chemical substances, we should be even healthier.
That's a little hard to take for those who have physical anomolies that are out of the normal range and are advised that they can be cured with exercise or diet.
The frustration of not being able to control cholesterol, triglycerides or weight with lifestyle changes sometimes leads to a feeling of failure and a loss of self esteem, especially with younger people.
As to drugs, studies, and "what they're not telling you... a simple internet search will bring up a "proof" for whatever the current health fad might be. All of the theories are backed with scientific truths to suit the predilection of the source.
Alternate medicine... Homeopathy, Ayurveda, Chiropractic and Acupuncture, and natural alternatives to drug remedies all have strong adherents, many of whom are absolutely certain that they have discovered the holy grail of eternal life.
Coming from an era when "drugs" and were limited to aspirin, milk of magnesia, Cuticura, Dristan and Tums, ... I see the growth of the pharmaceutical industry as being the single, most amazing evolutionary event since the invention of printing.
Practical thought?... Do whatever works. Try whatever sounds good and logical, watch for side effects, and keep an open mind. This curmudgeon lived through the "discovery" of cholesterol and the first tests of cholesterol level... went through 6 different 'statin drugs with limited results... original cholesterol at 380, and when triglycerides became de rigueur... off the scale at 1000+. Lipitor worked but resulted in severe muscle ache and muscle loss. Finally, a few years ago, settled on fenofibrate, which brought the readings down to borderline high. Total Cholesterol 200, Triglycerides 240.
With all of that, I am not sure that any of this is good, bad, or indifferent. Overall health is pretty good... no serious health problems (except for normal age related arthritis, some neuropathy, and slow onset of some kind of dementia.) DW thinks my early days as an athlete helped. And so we continue... doing whatever seems right or logical, and trying to figure out who to believe. So far, so good.
