It’s true, an apple a day does keep the doctor away

New evidence in a study by Scientists at the Chinese University of Hong Kong supports the old saying ‘an apple a day keeps the doctor away’.

Or to put it in rather more scientific terms, the research published in the Journal of Agricultural and Food Chemistry indicates that consumption of Apple polyphenols (AP) which are an excellent source of dietary antioxidants, extended the average lifespan of fruit flies by up to 20%.

It is known that free radicals in the body, although necessary to good in health in killing bacteria, are also believed to be involved in cell injury and death which results in many diseases such as cancer, stroke, myocardial infarction, diabetes and cancer.

Antioxidants can combat this damage and fruit and vegetables in the diet, especially brightly colored foods like tomatoes, broccoli, blueberries and apples are all excellent sources.

Previous studies indicated that an apple antioxidant could extend average lifespan and in their current report, the researchers used fruit flies to study whether Apple polyphenols, could do the same thing.

The results showed they not only prolonged the average lifespan of the flies but also helped preserve their ability to walk and climb. Furthermore, APs reversed the levels of various biochemical substances found in older fruit flies and used as markers for age-related deterioration and approaching death.

Spokesperson, Zhen-Yu Chen said that the results support those from previous studies, including one in which women who ate apples regularly had a 13-22 percent decrease in the risk of heart disease and further enhance the popular perception of the apple as a healthy food.
