New research has shown that broccoli and Brussels sprouts could be the most beneficial when it comes to preventing advanced blood vessel disease. The research, published in the British Journal of Nutrition, has found higher consumption of cruciferous vegetables, such as broccoli, Brussels sprouts and cabbage, is associated with less extensive blood vessel disease in older women.
Using data from a cohort of 684 older Western Australian women recruited in 1998, researchers from ECU's School of Medical and Health Sciences and The University of Western Australia found those with a diet comprising more cruciferous vegetables had a lower chance of having extensive build-up of calcium on their aorta, a key marker for structural blood vessel disease.
Eurekalert.org quoted lead researcher Dr Lauren Blekkenhorst as saying there was something intriguing about cruciferous vegetables: "In our previous studies, we identified those with a higher intake of these vegetables had a reduced risk of having a clinical cardiovascular disease event, such as a heart attack or stroke, but we weren't sure why. Our findings from this new study provides insight into the potential mechanisms involved."
"We have now found that older women consuming higher amounts of cruciferous vegetables every day have lower odds of having extensive calcification on their aorta. One particular constituent found abundantly in cruciferous vegetables is vitamin K which may be involved in inhibiting the calcification process that occurs in our blood vessels."
