Potassium in the Diet
Knowing how they work together, you may not be surprised to hear that our other old friend, potassium, also plays a part.
Just as too much sodium in the diet is known to contribute to high blood pressure, so is too little potassium. In fact, there's evidence to suggest that increasing your potassium intake can actually help to lower blood pressure.
With the average British diet containing just 80% of the recommended daily intake of potassium, any increase is likely to be beneficial for most people.
Getting the balance right
Sodium and potassium work together to control your blood pressure. Sodium pushes it up and potassium pulls it down. Ideally, you need to cut your sodium level along with making an effort to eat more foods rich in potassium*.
Good sources of potassium include:
- leafy green vegetables, such as spinach, parsley, lettuce, broccoli and peas
- fruits, including bananas, avocados and dried apricots
- wholegrains, such as wheat germ, seeds and nuts
- fish, including salmon, cod and sardines and

A word of caution
Most people know processed foods often have large amounts of salt added, but few realise most also have potassium removed, pushing blood pressure higher and higher.
* Please note that increasing your potassium intake won't - on its own - remove the need to reduce your salt intake. Too much potassium can also be harmful, which is why people receiving medication for diabetes, heart or kidney disorders should consult their doctor before using a reduced sodium salt.
