Pros and cons of the impact of coffee on the body continues to grow. Previously, coffee is said to potentially increase the risk of cancer. However, recent research called coffee is beneficial to improve cardiovascular health.
The recently published study in PLOS Biology concluded consuming four cups of coffee a day can help cardiovascular cells from damage.
Researchers from Heinrich-Heine-University and IUF-Leibniz Research Institute, Environmental Medicine in Düsseldorf, Germany, found that caffeine can improve the health of cells lining the arteries and veins, thus strengthening the cell’s ability to repair itself.
In a study developed on mice, researchers found caffeine may protect heart damage in pre-diabetic, obese, and old rats.
According to the study, caffeine induces the movement of a protein called p27 into the mitochondria. As a result, the movement can protect the heart muscle cells from cell death and help improve heart muscle.
“Our results show a new action on caffeine that protects and improves cardiac muscle through p27 mitochondrial action,” said researcher Professor Judith Haendeler, quoted by The Independent on Saturday (23/6).
Haendeler explains this result can be one strategy to protect the heart from damage.
The study even suggests parents or elderly to drink coffee or other caffeinated beverages because it is beneficial to reduce the risk of heart disease. However, the researchers also concluded the dose of four cups of coffee is the optimum measure for humans.
Reported by The Independent, professor of the University of Sheefield Tim Chico assessed the need for further proof on coffee that is beneficial to the heart.
“The results of this study are very interesting, but need to be confirmed in clinical trials before we can say caffeine is beneficial to the heart, I do not think people should drink coffee after knowing this research, but people who have been drinking coffee can be sure that coffee is beneficial.
