aljada. you seem balls deep in the medical books.
what they don't tell you is people are real people, and the books are a VERY VERY wide generalization.
tell me i'm wrong, 4000 people in a study, nothing tracked about food intake, not about how they live their life, its pure generalization.
ask yourself. are you 1 in a million? or are you a general fat slob like 57% of the population? digest that a while and maybe that will make you a better doctor.
doctors are far from always right, infact, most the time they clutching at straws and "using the book" because they cant think for themselves.
others have years and years of observation... wanna know how chemistry and electricity and the human body was discovered how it works? OBSERVATION. testing it on themselves.
don't recite your text book, google has that. tell me something i don't already know, please.
Doctors may not always be right but they have an absolute shit load better chance of being right than a loony off his pills googling crack pot web sites.
