High Blood Pressure
In this case, it depends on how you eat your nuts and seeds. If they are raw and unsalted, they can conceivably help lower your blood pressure. However, most come salted to improve their taste. Many of us already eat too much salt, which generally works in partnership with potassium to regulate the fluid balance in our bodies. When that critical balance is off, it drives up blood pressure.
It is best to eat unsalted varieties, but if you are otherwise careful with your sodium consumption, you can cheat a little by choosing unsalted nuts or seeds and adding just a little bit of salt at home. It is sure to be less than the packaged product. Another great strategy is to flavor your seeds or nuts with herbs like Italian seasoning or chili powder to add flavor without sodium.
