Heart disease is among the most widespread illnesses worldwide. Diet, exercise, and smoking have long been recognized as key factors.
A new study now highlights certain plant-based compounds that many people already consume as part of their everyday diet that can protect their heart.
Common foods in focus
Polyphenols are natural compounds found in foods such as berries, coffee, cocoa, nuts, and olive oil.
They are also part of dietary patterns such as the Mediterranean diet, which has previously been linked to better heart health.

According to Medical News Today, researchers believe that polyphenols may help explain these associations.
Ana Rodriguez-Mateos, a professor at King’s College London, explains that diet is one of the factors people can most easily change to reduce the risk of heart disease.
A long-term study
According to the researchers, who published the study in BMC Medicine, more than 3,100 adults were followed for more than ten years.
Participants reported their dietary habits, and a smaller group also had their polyphenol levels measured through urine samples.

The results showed that people with higher levels of polyphenols in their bodies often had a lower estimated risk of cardiovascular disease, as well as higher levels of so-called “good” cholesterol.
Practical implications
The risk of heart disease increased more slowly among those who consumed the highest amounts of polyphenol-rich foods.
External experts note that polyphenols have anti-inflammatory and antioxidant properties.
Foods such as berries, coffee, and nuts are already part of many people’s diets.
