A recent study showed that an apple a day keeps age-related fragility away, in new medical evidence of the many benefits of apples in the health field.

According to the American Journal of Clinical Nutrition, research indicates that eating foods that contain certain nutritional compounds, particularly blackberries and apples, can reduce your chances of becoming frail and sensitive as you age.

The substances referred to are known as “flavonols”, and they have been linked to a variety of health benefits, and they are found in a range of fruits and vegetables.

To investigate the possible link between flavonols and frailty – which affects 10 percent of adults over the age of 65 – the researchers analyzed the diets and vulnerability status of 1,701 people over a 12-year period.

During the study period, 13.2% of the participants developed weakness. The analysis revealed that for every additional 10 milligrams of flavonols people eat each day – such as a medium-sized apple – the odds of developing weakness decreased by 20%.

One flavonol in particular, called quercetin, has the strongest link to preventing frailty, the team said. This is mainly found in the likes of apples, dark berries, citrus fruits, onions, parsley and sage.
The researchers said: “There may be some truth to the old adage ‘an apple a day keeps the doctor away’.”

According to Age UK, “vulnerability” refers to a person’s mental and physical resilience, or their ability to recover from events such as illness and injury. It is generally characterized by problems such as decreased muscle tone and fatigue.
