Daily consumption of these red fruits improves heart health

This is indicated by the results of a study just published in the journal Food & Function which highlights the significant benefits of cranberries in the prevention of cardiovascular disease.

The daily consumption of cranberries, also known in Italy by their English name, i.e. cranberries, has been shown to improve heart health and, in particular, the function of the endothelium, the tissue that lines the inside of the walls of heart muscle, blood and lymph vessels. The results of a study just published in the journal indicate that Food and function by an international research team, which also involved researchers from the University of Parma.

In particular, the analysis evaluated the effect of consuming 9 grams per day for a month of freeze-dried cranberry powder, equivalent to 100g fresh cranberries, compared to placebo, in 45 healthy adults aged 18-45 years. The powder, which was dissolved in 500ml of water, was taken in the morning, with breakfast, and the research participants’ vascular measurements were taken both after an overnight fast and 2 hours later. the intake, the first day and after one month of daily consumption.

Analyzes indicated that cranberry consumption significantly improved endothelial function two hours after the first consumption and after one month, and that this improvement was linked to specific metabolic profiles in plasma. “The increase in polyphenols and metabolites in the bloodstream and associated improvements in flow-mediated vasodilation following consumption of cranberries underscore the important role these fruits can play. in the prevention of cardiovascular diseases – said Ana Rodriguez-Mateos, corresponding author of the study and senior lecturer in nutrition at the Department of Nutritional Sciences at King’s College London. The fact that these improvements in cardiovascular health have been observed with a reasonably edible amount of cranberries each day makes this fruit an important player in the prevention of cardiovascular disease for humans in general.“.

Our results – added Christian Heiss, Director of Research and Professor of Cardiovascular Medicine at the University of Surrey, Guildford, UK – provide strong evidence that cranberries they can significantly affect vascular health also in people at low cardiovascular risk, also indicating that specific metabolites present in the blood after cranberry consumption are linked to the beneficial effects“.
