Apple a day advice true

(AAP) Yes it appears to be true, eating an apple a day can keep the doctor away.

A US study focused on a group of cyclists who underwent three days of intense training while taking a supplement containing quercetin – the antioxidant found in apples.

In the two weeks following the training, only five per cent of the group went on to experience an upper respiratory tract infection compared to 45 per cent of a rival group which took a placebo.

Australia-based dietitian Karen Kingham says the research showed how apples could help to boost a person’s immune system ahead of winter.

“Quercetin has been shown to have both antiviral and antibacterial effects, and apples are the second highest contributor of dietary quercetin intake in the Australian population next to black tea,” she says.

And there are other benefits.

A man’s semen quality also depends upon his antioxidant intake, Spanish scientists have found.

Researchers probed the dietary habits of 60 couples who were seeking help at two infertility clinics.

It followed a study which found men who ate large amounts of meat, and full fat dairy products, tended to have lower sperm counts.

“Among the couples with fertility problems coming to the clinic, the men with good semen quality ate more vegetables and fruit,” says Jaime Mendiola, a researcher at the University of Murcia.

“In this study, we have found that people who consume more fruits and vegetables are ingesting more antioxidants, and this is the important point.”

The research is published online in the journal Fertility and Sterility.
