The fruits richest in quercetin, an antioxidant that is part of the flavonoids, would reduce the risk of frailty syndrome which affects 10% of people over 65 years old.
We all know the old saying, “An apple a day keeps the doctor away”. It would seem that the ancients were not wrong since researchers at Harvard University (USA) have just demonstrated in a study that fruits rich in flavonoids (of which the apple is a part) made it possible to prevent the fragility of the elderly.
To study the link between flavonoids and frailty syndrome, which affects 10% of adults over 65, the researchers analyzed the diet and state of frailty of 1701 people for 12 years.
An apple and a few blackberries every day
During this time, almost 13% of participants developed frailty, and upon closer examination of their diets, scientists found that an additional 10 mg serving of quercetin (an antioxidant that is part of the flavonoids) consumed per day, the equivalent of an average-sized apple, reduced the risk of frailty by 20%. Quercetin is most commonly found in apples and blackberries.
“This study highlights the importance of evaluating specific flavonoid subclasses and the potential of quercetin as a strategy to prevent the development of frailty,” the researchers explained.
