Pistachio
Pistachios are amazing for reducing blood pressure because it reduces peripheral vascular resistance. What that means is that is it reduces the tightening of blood vessels, leaving more room for blood to flow, which can help improve your heart rate. What you can do is to eat them as a snack in a bowl, combine them with cranberries to make some energy balls or eat them with apples and some low-fat cream cheese. Just keep in mind that some pistachios contain more fat than other nuts, so weight gain is possible if you eat too many of these.
