Heart attack patients have typically been put on low-fat diets to help prevent a recurrence in the future, but that may no longer necessarily be the case. A new study shows that a Mediterranean style diet (including "healthy" fats like olive oil) is just as effective at reducing further cardiovascular incidents as the more usually recommended low-fat American Heart Association diet.

Interestingly enough, the patients in the study who were put on the Mediterranean diet had a harder time following it -- despite being allowed more fat. Apparently, since they were mostly older individuals, they weren't used to eating so much fish and seafood.
