Few cranberries daily improves cardiovascular health
A double-blind, parallel-group, randomized controlled trial was conducted in 45 healthy male adults. Randomly allocated to 1 month daily consumption of either cranberry (9 g powder equivalent to 100 g of fresh cranberries, 525 mg total (poly)phenols) or a placebo for one month.

Flow-mediated dilation (FMD, primary outcome), pulse wave velocity (PWV), aortic augmentation index (AIx), blood pressure, heart rate, blood lipids, and blood glucose were assessed at baseline and at 2 h on day 1 and after 1 month.

Those consuming cranberry had a significant improvement in flow-mediated dilation (FMD), which signals improvement of heart and blood vessel function. FMD is considered a sensitive biomarker of cardiovascular disease risk and measures how blood vessels widen when blood flow increases.

The fact that these improvements in cardiovascular health were seen with an amount of cranberries that can be reasonably consumed daily makes cranberry an important fruit in the prevention of cardiovascular disease for the general public.

Low consumption of fruits and vegetables is one of the top modifiable risk factors associated with a higher incidence of cardiovascular disease worldwide.
