Good Oil, Bad Oil?

What's one to do -  eat a diet low in all fats, one with "healthy" fats like fish oils or one with a mixture of saturated as well as unsaturated fats?  The answer is that there is no right answer at this point.  It could depend on genetics, so what's right for you isn't right for me and it could depend on what disease you are trying to fight.  Newly analized old studies and more recent studies on diet and heart disease point to shortened life expectancy for men following low saturated fat diets.  The long held belief that high cholestoral leads to heart disease is also being called into question.   When in doubt I like to think of the  Chinese dietary traditon of eating all things, but in moderation.
