Tried "high blood pressure" which has to be one of the most common concerns and got weird results. It started talking about ethnicity (not something you change in an intervention) and how Hispanics had a really high 145 diastolic and Blacks had a really low 144 diastolic (makes no sense) but didn't say anything to the effect that "if your are in ethnic group A you should try intervention B".
There's a short list of supplements which seem to help blood pressure such as dark chocolate, garlic, magnesium, L-citrulline, nitrates and it didn't mention one. Not killing examine.com just yet.
