Despite years of being told fat should be stripped out of our diets, sources of good-quality fat such as nuts, seeds, and extra virgin olive oil feature heavily in Mediterranean diets, which are heart-healthy. Whole sources of fat such as pecans, walnuts, sunflower seeds, and minimally processed extra virgin olive oil are fantastic additions to your diet from a heart-health perspective. Not only do they contain key minerals like selenium and magnesium, but they provide antioxidants such as vitamin E, which can protect the heart from oxidative stress.
