Eating foods rich in polyphenols can boost heart health, recent research shows. This study from King’s College London tracked over 3,100 adults for more than a decade. It found that those who included more polyphenol-rich foods in their diets had a lower risk of cardiovascular disease as they aged.
Ana Rodriguez-Mateos, a professor at King’s College, explains, “Long-term commitment to a diet rich in these compounds can slow the rise in cardiovascular risk. Even small but consistent changes, like adding berries or nuts, can help.”
As we age, our risk for heart issues naturally increases, but the study suggests that greater polyphenol intake can slow this process over time. Participants with higher levels of these compounds showed healthier blood pressure and cholesterol levels. Specifically, they had more of the “good” HDL cholesterol, which helps protect the heart.
Polyphenols are plant-based compounds known for their health advantages, including benefits for the heart, brain, and gut. The study analyzed many metabolites in urine, indicating that those consuming higher amounts of polyphenols, especially flavonoids and phenolic acids, had lower cardiovascular risks.
To measure polyphenol intake, researchers created a dietary score focusing on 20 key foods popular in the UK, like tea, coffee, berries, and olive oil. This approach provided a clearer picture of how these foods work together to support heart health.
Dr. Yong Li, the study’s first author, noted, “Incorporating polyphenol-rich foods into your diet is an easy and effective way to protect your heart. These compounds are found in everyday foods.”
Looking ahead, researchers emphasize the need for more studies to validate these findings. In parallel, recent studies in Spain revealed that heating fruit and vegetable smoothies can enhance polyphenol absorption in the gut. This might improve health benefits while also extending shelf life.
Moreover, a study on pomegranate extract demonstrated that daily intake of a high-polyphenol supplement can boost certain growth factors in older adults, which typically decline with age. This shows promise for supporting overall health as we grow older.
These insights highlight not only the power of simple dietary changes but also the growing interest in the science behind our food choices. Regularly enjoying foods rich in polyphenols can be an easy step towards better heart health.
