The big professional associates generally put out a set of consensus guidelines that are aimed at giving "physicians in the trenches" a (relatively) easy interface as to "best practices" in terms of preventative medicine and risk reduction. That being said, this is a matter of separating the noise from the signal in the population which is quite hard. AFAIK, and I am probably missing a few, but the only real long term modifiers are aspirin, low blood pressure, and high fiber/low cholesterol/low glycemic index foods. Everything else - there isn't enough data to separate noise from signal except for a few specific cases (someone found a gene polymorphism or mutation to something specific, i.e. the risk of blue converse sneakers or something like that)
