Citrus Fruits May Lower Risk of Stroke

A new study recently published examined how consuming flavonoids affect the risk of stroke.

Data from more than 69,000 women who took part in the 14-years of follow-up from the Nurse's Health Study was used in the analysis. The researchers examined the relationship of the six main subclasses of flavonoids commonly consumed in the diet--flavanones, anthocyanins, flavan-3-ols, flavonoid polymers, flavonols and flavones--with risk of ischemic, hemorrhagic and total stroke

Although the results did not find any beneficial association between total flavonoid consumption and stroke risk, they did find that consumption of high amounts of certain flavonoids lowered ischemic stroke risk.

Specifically, women who ate high amounts of flavanones in citrus had a reduced risk of blood clot-related (ischemic) stroke than women who consumed the least amounts.

“Over 14 years of follow-up, high flavanone intake was associated with a 19% lower risk of ischemic stroke, a finding that fits with existing data on the protective effect of citrus fruit consumption,” said the researchers.

  1. I think studies like this go to show that it's not necessarily any one particular food or compound that will prevent disease, but an overall healthy diet and lifestyle.
    Like many things, this study shows high consumption of flavanones will lower risk of stroke --> PREVENTION.
    I doubt the flavanones would do much to TREAT someone already at risk of a stroke.

  2. I wonder if orange juice counts or if it needs to be whole fruit?

    1. Good question. Wondering the same

  3. Not sure what the answer to this question is... I guess it depends on whether the flavonones are water soluble, and if so, where are they found in the fruit, and how the juice is extracted. I'm sure with a little digging, we'd be able to flush out the right answer.

    My guess is that flavonones are water-soluble, but how much is found in the juice is a mystery to me.

    If any one knows the answer to this, please add your comment.

  4. Well, I looked into it... Looks like flavonones ARE found in the juices citrus fruits, wih orange and grapefruits being the best sources.
