Where would we be without Polyphenols? These superstars of the phytochemical world are in many of the foods we eat, especially those that are naturally deeply coloured and flavoured. Whilst there have been many studies that look at their beneficial effects, a recent study speaks to the benefits of small, sustained increases in their consumption.
In a recently published study, researchers from King's College, London, found that eating polyphenol rich foods, such as tea, coffee, berries, nuts, and whole grains—on a regular basis may help protect heart health over time. In a 10-year study of more than 3,100 adults, people who consistently consumed more of these foods tended to have healthier blood pressure and cholesterol levels and a lower estimated risk of cardiovascular disease.
Professor Ana Rodriguez-Mateos, senior author and Professor of Human Nutrition at King's College London, said: "Our findings show that long-term adherence to polyphenol-rich diets can substantially slow the rise in cardiovascular risk as people age. Even small, sustained shifts towards foods like berries, tea, coffee, nuts, and whole grains may help protect the heart over time."
This is good news for those that regularly eat these foods and another great reason to consume more of these if you don't eat enough already.
