Blueberries could reduce your risk of "fifth" heart disease (but you would have to eat a punne a day for a month)
- Consume 200 g per day for one month improves the functioning and pressure of blood vessels
- "Super" berries could be as effective as the prescribed blood pressure pills. In the UK, 7 million people live with heart and circulatory diseases.

According to a new study, blue in blueberries could reduce the risk of heart disease by 20%.
The researchers found that consuming 200 g of blueberries a day for a month – a large slip – improved blood vessel function and lowered blood pressure in healthy people.
In addition, the study suggests that "super" berries could be as effective as the blood pressure pills prescribed by the doctor.
And all because of a magic chemical that gives the bay its blue color known as anthocyanin.
Hue: The health benefits derive from a magical chemical that gives the bay its blue color known as anthocyanin.
High blood pressure is the leading cause of cardiovascular disease and, if ignored, can cause heart attacks, strokes and kidney disease.
Researchers at Kings College London have badyzed the effects of consuming blueberry juice every day for a month – and the results could save lives.
The principal researcher, Dr. Ana Rodriguez-Mateos, said: "Although it is best to eat all the blueberries to get the most out of them, our study shows that the majority of the effects can be explained. by anthocyanins.
"If the observed changes in blood vessel function after daily consumption of blueberries could last a lifetime, the risk of developing cardiovascular disease could be reduced by 20%.
She added: "Blueberries are rich in polyphenols, especially in anthocyanins, but also contain other phenolic compounds in smaller amounts such as procyanidines, flavonols and phenolic acids, as well as a source rich in fiber, vitamins and minerals.
"Blueberries were initially studied because of their potential beneficial effects on the decline of age-related cognitive function, but they have recently been shown to improve cardiovascular function.
Avoidable: in the United Kingdom, 42,000 people under the age of 75 die each year from cardiovascular disease
"The data from the Nurse Health Study II showed that a high consumption of blueberries and strawberries and a high consumption of anthocyanins (calculated using food frequency questionnaires) were inversely badociated with the risk of myocardial infarction. "
The study of 40 participants received either a glbad containing 200 g of blueberries to drink daily, or a placebo.
The blood pressure, urine and blood of all volunteers were tested, as well as their flux – induced dilatation (FMD), which measures the extent of enlargement of the body. artery when blood flow increases.
FACTS ON HEART DISEASE
In the UK, about 7 million people live with heart and circulatory diseases. A growing and aging population and improved survival rates from heart and circulatory accidents could see these numbers increase further.
Heart and circulatory diseases account for a quarter (25%) of deaths in the UK; That's more than 150,000 deaths each year, an average of 420 people per day or one death every three minutes.
In the United Kingdom, approximately 42,000 people under the age of 75 die from CVD each year.
Since the creation of the BHF, the annual number of deaths from heart and circulatory diseases in the UK has decreased by more than half.
In 1961, more than half of deaths in the United Kingdom were attributable to CVD (320,000 deaths).

The researchers compared the results of blueberry and placebo drinkers and discovered that purified anthocyanins – the phytochemical that gives fruits and vegetables a blue, red, pink or purple color – have a considerable impact on the arterial pressure.
They found that consuming 200 g of blueberries significantly improved blood vessel function in less than two hours.
After a month of daily consumption of fruit juice, blood pressure decreased by 5 mmHg – a similar drop experienced by people taking blood pressure medication.
Drinks containing purified anthocyanins also resulted in improved endothelial function, which is essential for the regulation of blood pressure and blood clotting.
Dr. Rodriguez-Mateos said, "Although blueberries contain many potentially" healthy "bioactive molecules, including vitamins, fiber, and minerals, our current results demonstrate that anthocyanins are major bioactive compounds that can explain why Increased endothelial function after consumption of blueberries.
"Our data demonstrate for the first time that purified anthocyanins lead to dose-dependent improvements in endothelial function.
In conclusion, our results demonstrate the key role of anthocyanin metabolites in mediating the biological activities of blueberries that can contribute to healthy cardiovascular aging.
"We provide additional scientific evidence that chronic bilberry consumption in healthy humans results in long-lasting cardiovascular benefits related to circulating metabolites of anthocyanin and modulation of cellular gene programs toward an anti-cancer protection profile." -Inflammatory and anti-MCV "
The study was published in the Journal of Gerontology Series A.
