Mayo Clinic Health Letter

I just got a solicitation for this magazine (a one month free trial). Is it really from the Mayo Clinic? Is the advice good? Yes, I could get the trial, but I am in no position to judge if their advice is good. If I could, I likely wouldn’t need it. Any Dopers have experience with this?

Have you looked at the online edition? —> http://healthletter.mayoclinic.com/
