Sorry for the free plug for a guy who comes off as (and in many ways is) a crank, but that's almost verbatim the health policy preferred by Nicholas Taleb (of Black Swan /Anti-fragile fame):

- Be very conservative in what foods/medicines you use, limiting yourself to those with a proven track record.

- Ignore warnings about specific figures (e.g. cholesterol, blood pressure) if you're otherwise healthy and active.

- If you have a terminal condition, take risky treatments since you have little to lose.
