Certain foods beyond the well-known culprit of salt can significantly raise blood pressure

High blood pressure affects millions of Britons, but there are natural ways to manage it without medication.

While adopting a balanced diet rich in magnesium, potassium, and calcium is one of the most effective approaches, hidden ingredients can undermine these efforts by sneaking into the diet.


Cardiology dietitian at Entirely Nourished, Michelle Routhenstein, told GB News many people are unaware certain foods like processed fruits (those that have been dehydrated/canned etc) and fruit juices significantly raise blood pressure.

This is because underlying factors like insulin resistance can make a significant difference in blood pressure readings.

Fructose is an unexpected contributor to high blood pressure

Fructose is an unexpected contributor as excess intake can promote insulin resistance, which in turn causes the body to retain sodium and elevate blood pressure.

"Foods high in fructose include sugary snacks, fizzy drinks and processed fruits or fruit juices," Michelle cautioned.

She added: "For some people, excessive caffeine can lead to an increase in blood pressure as well."

Problematically, even the main culprit - sodium - lurks in many everyday foods that Britons might not suspect.

Items like jelly, pudding, bread and sauces often contain surprising amounts of sodium, underscoring the importance of checking nutrition labels.

Other causes of high blood pressure

Regular physical activity, stress management, and ensuring adequate sleep all play a crucial role in maintaining healthy blood pressure levels.

Weight management is another key component of a comprehensive approach to natural blood pressure control.

The good news is that once dietary changes are made, they can impact blood pressure relatively quickly.

Michelle noted: "Dietary changes can have a significant impact on blood pressure relatively quickly, often within two to four weeks.

"In my private practice, I have helped many reduce their blood pressure by 20 to 30 points within just two weeks by making personalised dietary adjustments."

Over time, improved sleep, combined with more stable blood sugar levels, supports overall blood pressure control.
