According to the South Gerontopole of Marseillenearly 40% of seniors aged 65 and over show signs of frailty and pre-frailty.
The frailty syndrome (which is defined as “a decrease in physiological reserve capacities that impairs the mechanisms of adaptation to stress”) associates involuntary weight loss, a subjective feeling of exhaustion, muscle weakness, walking speed slow and a significant sedentary lifestyle. It is a risk factor for early mortality.
Quercetin every day for frailty
Dutch and American researchers carried out a study to assess the impact of diet (and especially: the daily intake of antioxidants) on the risk of developing frailty syndrome around the age of 60.
For this, the researchers followed 1701 volunteers (aged 58 on average at the start of the study) for 12 years. Result ? They found that, on average, people who consumed flavonols (and, in particular, quercetin) daily had a lower risk than others of developing frailty syndrome. In detail, for each level of + 10 mg of quercetin consumed per day, the risk of frailty decreased by approximately 35%.
Where is quercetin found? Good news: two “everyday” fruits contain interesting amounts of quercetin – these are apples (with 4 mg per 100 g) and grapes (1 mg per 100 g approximately). Fruits that can therefore be eaten every day to stay healthy longer!
