Non mettete latte nel vostro te: lo dicono alcuni ricercatori crucchi

[are(a)zione]

A small German study found drinking black tea significantly improved the ability of arteries to relax and expand to keep blood pressure healthy.
But the European Heart Journal paper also found proteins in milk, called caseins, blocked this effect.


It is estimated as many as 98% of UK tea-drinkers prefer milk in their favourite cuppa.
The researchers tested the effects of tea in 16 humans and on rat tissue.
They showed molecules in the tea called catechins helped dilate the blood vessels by producing a chemical called nitric oxide. The caseins in milk prevented this effect by reducing the concentration of catechins in the tea.


Our results provide a possible explanation for the lack of beneficial effects of tea on the risk of heart disease in the UK


Professor Stangl


Senior researcher Dr Verena Stangl, professor of cardiology at the Charite Hospital, in Berlin, said: "Our results thus provide a possible explanation for the lack of beneficial effects of tea on the risk of heart disease in the UK, a country where milk is usually added."
However, June Davison, cardiac nurse at the British Heart Foundation (BHF), said: "It is difficult to say from this small study the impact of adding a drop of milk to your tea can make.
"The tea break is a great British tradition which provides time to relax with a cuppa in hand.
"Leaving milk out of your tea is far less likely to help protect your heart health than other measures, such as taking regular exercise, avoiding smoking and eating a healthy balanced diet."
