Sun-ripened strawberries on oatmeal; a handful of walnuts to get through that 4 o’clock slump; grilled salmon, roasted veggies and a salad drizzled with olive oil for dinner: At last, we’ve got solid proof that scrumptious foods like these can slash your risk for stroke and other cardiovascular disasters by a whopping 30 percent. It’s thanks to a headline-grabbing study from Spain that overhauled the diets of 7,447 people (even though the researchers made a big flub when they conducted the study; more on that in a minute!).

Two-thirds of the study’s participants conscientiously followed heart-healthy Mediterranean diet plans — plenty of produce, dried beans and fish, with an extra dose of good fats from olive oil or nuts.
