Stroke in Women and Dietary Flavonoids

By: Alere Staff

An apple a day is said to keep the doctor away but a new study suggests that oranges and other citric fruits may keep a certain type of stroke away, or at least reduce your risk for a certain type of stroke. A study of more than 69,600 women in the United Kingdom looked at the affect of a natural product called flavanone. The results were published in the February issue of Stroke, a journal of the American Heart Association.

Flavonone is a flavonoid compound commonly found in citrus fruits such as oranges, grapefruit, and their juices. They are also commonly found in tea and apples. This compound was suggested to lower a woman’s risk of ischemic stroke (a stroke caused by a blood clot in the brain), but had no affect on another type of stroke called a hemorrhagic stroke (a stroke caused by bleeding in the brain).

There was a 19% reduced risk of ischemic stroke in women with the lowest in-take of 97 mg/day of flavanone compared to women consuming the highest in-take of 761 mg/day.1

Large consumption of orange juice and other sugar based citrus fruits should be eaten with caution as they contain high levels of sugar which, in addition to having a lot of calories, may increase your risk of developing diabetes.

You should discuss any changes in diet with your doctor or nurse before starting or stopping any new foods or even increasing or decreasing amounts you currently intake. If you take warfarin, a simple adjustment of your dose by your physician (if needed) will allow you more choice of foods – some of which may prevent your risk of a stroke.
