High blood pressure is a serious health problem that can cause hardening and thickening of the arteries. This can then lead to the development of health complications such as heart and stroke. There are several risk factors for a person who develops high blood pressure, some of which are related to poor dietary choices. Eating a large amount of salt in foods and drinking regularly large amounts of alcohol are known to increase blood pressure.
To counteract these poor dietary choices, the NHS recommends reducing your salt intake to less than 6g per day, following a balanced, low-fat diet, consuming less caffeine, and reducing your alcohol intake.
More specifically, studies have shown in particular that foods and beverages possess hypoglycemic qualities.
A study published in the British Journal of Nutrition in 2004 suggests that tea can help lower blood pressure.
But not any tea – green tea.
The researchers badyzed 25 randomized controlled trials, which are the gold standard for scientific research, to explore the badociation between tea and high blood pressure.
They found in the short term that tea did not seem to have any effect on blood pressure.
But in the long run, drinking tea has had a significant impact.
Research has shown that after 12 weeks of tea consumption, blood pressure was lowered by 2.6 mmHg systolic and 2.2 mmHg diastolic.
Systolic pressure is the highest reading figure and measures the force at which your heart pumps blood throughout your body.
The diastolic pressure is the lowest reading figure and measures the resistance of the blood flow in the blood vessels.
Green tea has had the most significant results. Black tea was the second best.
Although the change in blood pressure reading may seem minimal, the researchers wrote that reducing systolic blood pressure to 2.6 mmHg "should reduce the risk of stroke by 8%, mortality from coronary artery disease." of 5% and all causes mortality of 4% at the population level ".
The researchers in this study have not been able to determine the number of cups of green tea that you should drink daily to lower your blood pressure, but other studies have suggested that three to four cups of tea a day could be effective.
The onion is a food that has antihypertensive properties.
Its powerful anti-inflammatory properties can help reduce high blood pressure and quercetin, a flavonoid antioxidant highly concentrated in onions, can also be effective.
A study involving 70 overweight people and suffering from high blood pressure revealed that a dose of 162 mg per day of quercetin-rich onion extract significantly reduced systolic blood pressure from 3 to 6 mmHg compared to a placebo.
