High blood pressure: ‘Too little’ potassium means ‘sodium can build up in your blood’

The NHS says: “Eating a healthy, balanced diet is an important part of maintaining good health, and can help you feel your best.

“This means eating a wide variety of foods in the right proportions, and consuming the right amount of food and drink to achieve and maintain a healthy body weight.”

It says: “Most people in the UK eat and drink too many calories, too much saturated fat, sugar and salt, and not enough fruit, vegetables, oily fish or fibre.”

The Mayo Clinic adds that regular physical activity, such as 150 minutes a week, or about 30 minutes most days of the week, “can lower your blood pressure”.
