Heart Healthy Food: Eating Cranberries Daily Improves Cardiovascular Health

A new scientific trial discovered day-to-day usage of cranberries for one month improved cardiovascular function in healthy males.
The new research study, released on March 22, 2022, in Food & & Function, included 45 healthy men who consumed entire cranberry powder equivalent to 100g of fresh cranberries per day (9 g powder) or a placebo for one 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 heart disease danger and determines how blood vessels expand when blood circulation boosts.

The new study, released on March 22, 2022, in Food & & Function, consisted of 45 healthy men who took in whole cranberry powder equivalent to 100g of fresh cranberries per day (9 g powder) or a placebo for one month. The pilot concluded that cranberry intake increased FMD and confirmed dosing. The main study was a gold standard study design examining 45 healthy males each taking in 2 packets of entire cranberry freeze-dried powder equivalent to 100g of fresh cranberries, or a placebo, daily for one month. These results conclude that cranberries can play an essential role in supporting cardiovascular health and good blood vessel function.

Dr. Ana Rodriguez-Mateos, Senior Lecturer in Nutrition at the Department of Nutritional Sciences at Kings College London and senior author of the research study, stated: “The increases in polyphenols and metabolites in the blood stream and the associated improvements in flow-mediated dilation after cranberry usage highlight the essential function cranberries may play in cardiovascular illness prevention. The truth that these improvements in cardiovascular health were seen with a quantity of cranberries that can be reasonably consumed day-to-day makes cranberry an essential fruit in the prevention of cardiovascular illness for the basic public.”
Low consumption of vegetables and fruits is among the leading modifiable threat elements related to a higher incidence of cardiovascular illness worldwide. Growing evidence continues to connect the polyphenols from berries with heart health advantages. Cranberries are rich in special proanthocyanidins that have actually unique properties compared to polyphenols found in other fruits.
This study explored entire cranberry freeze-dried powder, comparable to 100g of fresh cranberries, and its effect on cardiovascular health. The results demonstrated that consumption of cranberries as part of a healthy diet plan can help minimize the threat of cardiovascular illness by improving capillary function.
An initial pilot study was completed with 5 healthy young males to verify the biological activity of the whole cranberry freeze-dried powder. The pilot concluded that cranberry intake increased FMD and verified dosing. The primary study was a gold standard research study style taking a look at 45 healthy men each consuming 2 packets of whole cranberry freeze-dried powder equivalent to 100g of fresh cranberries, or a placebo, daily for one month. The study found considerable improvements in FMD 2 hours after very first usage and after one month of day-to-day consumption revealing both persistent and immediate advantage. In addition, metabolites were likewise identified and anticipated the favorable impacts seen in FMD. These outcomes conclude that cranberries can play a crucial function in supporting cardiovascular health and good blood vessel function.
Dr. Christian Heiss, Professor of Cardiovascular Medicine at the University of Surrey and co-author of the study stated: “Our findings provide strong evidence that cranberries can considerably impact vascular health even in individuals with low cardiovascular threat. This study further shows that particular metabolites present in blood after cranberry intake belong to the advantageous results.”.
