Diet: Drinking tea and eating apples can help fight low blood pressure and heart disease


Drinking tea and eating apples can help fight low blood pressure and heart disease, the study claims

  • Researchers studied the diet and blood pressure of 25,168 people from Norfolk
  • They measured flavanol intake using biomarkers instead of self-reporting
  • They found that a high flavanol diet can cause 4 mmHg low blood pressure
  • This is equivalent to the benefits of a Mediterranean or hypertensive diet

One study claimed that diets such as those found in apples, berries, and teas – such as blood, help lower blood pressure.

British and American researchers studied the diet and blood pressure of 25,168 people living in the English county of Norfolk.

They found that, on average, a person with a flavanol-enriched diet had blood pressure up to 4 mmHg (millimeter of mercury), lower than a person with a low flavanol intake.

This is similar to the ‘meaningful’ change in blood pressure in people who follow a Mediterranean or dietary approach to prevent a hypertension (DASH) diet.

A diet rich in flavanols – such as those found in apples, berries, and teas – may help lower your blood pressure and relieve heart disease, a study has claimed

Unlike previous studies that typically relied on people reporting their own food and beverage intake, the team used nutritional biomarkers – blood-based dietary intake, metabolism, or nutritional status to determine fluvol levels. did.

Nutritionist Günter Kuhnl from Paper University and Reading University said, “What this study gives us is an objective discovery about the relationship between flavanols and tea and some fruits and blood pressure.”

‘This research confirms results from previous dietary intervention studies and shows that the same results can be obtained with a habitual diet rich in flavanols.’

“In the British diet, the main sources are tea, cocoa, apples and berries,” he said.

“This is the largest study ever to use a nutritional biomarker to investigate bioactive compounds,” said Professor Kuhnl.

“The use of nutritional biomarkers to estimate the intake of bio-food compounds has been seen as the gold standard for research, as it allows measuring intakes objectively,” he said. ”

‘Unlike self-reported dietary data, nutritional biomarkers can address vast variability in food composition. We can therefore confidently attribute the characteristics we observed to flavanol intake. ‘

'This research corroborates the results from previous dietary intervention studies and shows that the same results can be obtained with a habitual diet rich in flavanols,' said the paper writer and University of Nutrition University of Gunter Kuhnan.

“This study provides important insights into the growing body of evidence supporting the benefits of dietary flavanols in health and nutrition,” said Mars Age’s Chief Science Officer, Hagen Schroter.

‘But perhaps even more exciting was the opportunity to implement biomarkers aimed at large scale flavanols intake.’

‘This enabled the team to avoid the significant limitations that come with previous approaches that depend on assessing intake based on self-reported food consumption data and shortcomings of current food composition databases.’

The full findings of the study were published in the journal Scientific Reports.

What if I have high blood pressure?

High blood pressure, or hypertension, are rarely noticeable symptoms. But if untreated, it increases your risk of serious problems like heart attacks and strokes.

More than one in four adults in the UK have high blood pressure, although many will not realize it.

The only way to find out if your blood pressure is high is to have your blood pressure checked.

Blood pressure is recorded with two numbers. Systolic pressure (high number) is the force at which your heart pumps blood around your body.

Diastolic pressure (low number) is the resistance of blood flow to blood vessels. They are both measured in millimeters (mmHg) of mercury.

As a general guide:

  • Hypertension is considered to be 140 / 90mmHg or more
  • Ideal blood pressure is assumed to be between 90 / 60mmHg and 120 / 80mmHg
  • Low blood pressure is considered to be 90 / 60mmHg or less.
  • If you do not take steps to keep blood pressure under control then a blood pressure reading between 120 / 80mmHg and 140 / 90mmHg may mean that you are at risk of developing hypertension.

If your blood pressure is too high, it puts additional pressure on your blood vessels, heart and other organs, such as the brain, kidneys, and eyes.

Chronic hypertension can increase your risk of many serious and potentially life-threatening conditions, such as:

  • heart disease
  • heart attack
  • Stroke
  • Heart beat stop
  • peripheral arterial disease
  • Aortic aneurysm
  • Kidney disease
  • vascular dementia
