Experts particularly observed the relationship between the six major subgroups of flavonoids (flavanones, anthocyanins, flavan-3-ols, flavonoid polymers, flavonols and flavones) and the risk of stroke.
Almost 70,000 women took part in US survey within 14 years which showed that orange and grapefruit provide excellent protection from stroke. Scientists believe that these results are significant for men as well.
A team of scientists from Norwich Medical School examined how much protection is provided by flavonoids, which are found in fruits, vegetables, dark chocolate and red wine.
Experts particularly observed the relationship between the six major subgroups of flavonoids (flavanones, anthocyanins, flavan-3-ols, flavonoid polymers, flavonols and flavones) and the risk of stroke.
It has been shown that there is a connection between women who eat a greater amount of flavanone (45 mg daily) of citrus – they have a 19% lower risk of sudden stroke associated with a blood clot than the women who ate smaller amount (20 mg).
In the glass of orange juice can be found from 20 to 50 mg of flavanones, depending on the method of production and storage.
The researchers note that it is better to eat fresh fruit rather than drink purchased juice because these juices can contain large quantities of sugar.
Lead researcher, nutritionist Aedin Cassidy says: “Studies have shown that a higher intake of fruits, vegetables and especially vitamin C is associated with lower risk of stroke. Flavonoids help in a way that are improving the condition of blood vessels and have anti-inflammatory properties”
