Flavonoids found in tea carry strong health benefits: study

Putting the kettle on every day could be key to a healthy life, according to an Australian study that found tea consumption in elderly women had positive effects.

The peer reviewed study assessing more than 800 elderly women found that flavonoids — a naturally occurring substance found in beverages such as black and green tea — could lead to notable health benefits.

The participants surveyed, all women with a median age of 80, were determined less likely to have an extensive accumulation of abdominal aortic calcification (ACC), a marker or various health risks, thanks to steady intakes of flavonoids in their diet.

The abdominal aorta, which is considered the largest artery in the body, transfers oxygenated blood from the heart to abdominal organs, and ACC stands as a reliable predictor of susceptibilities to heart attack, stroke, and, according to this recent study, cognitive degenerative diseases such as late-life dementia.

The study, which was conducted by researchers with the ECU Nutrition and Health Innovation Research Institute, identified that a cohort of elderly women with no history of cardiovascular complications largely benefited from having flavonoids in their daily diet.

Ben Parmenter, one of the study’s researchers, said numerous dietary sources hold flavonoids in high amounts, if tea isn’t to your liking.

“In most populations, a small group of foods and beverages – uniquely high in flavonoids – contribute to the bulk of total dietary flavonoid intake,” he said in the release.

“The main contributors are usually black or green tea, blueberries, strawberries, oranges, red wine, apples, raisins, grapes, and dark chocolate.”

The study, which was published in Arteriosclerosis, Thrombosis, and Vascular Biology, looked at women between the ages of 78 and 82 using food-frequency questionnaires and was adjusted for demographics, lifestyles and diet.
