Consuming cranberries for a month has been found to improve cardiovascular function in healthy adults in a study conducted by the Medical Faculty of Heinrich-Heine University Dusseldorf and the Dusseldorf Heart Centre.

What to know:

  • Daily consumption of freeze-dried whole cranberry powder in an amount equivalent to 100 g of fresh cranberries per day has been shown to improve heart and blood vessel function in healthy adults.

  • The study found significant improvements in flow-mediated dilation 2 hours after first consumption and both immediate and long-term benefit after 1 month of daily consumption.

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

  • Cranberries are rich in unique proanthocyanidins that have distinct properties compared to polyphenols found in other fruits.

  • Cranberries were found to increase polyphenols and metabolites in the bloodstream, which can help prevent blood clots, reduce blood sugar levels, and lower the risk for heart disease.
