When I make a salad or anything that needs oil, I always reach for the olive oil. It is regarded as a healthful dietary oil because of its high content of monounsaturated fat (mainly oleic acid) and polyphenols.

In a study to be published in the January 2007 issue of The FASEB Journal, scientists from five European countries describe how the anti-cancer effects of olive oil may account for the significant difference in cancer rates among Northern and Southern Europeans.

The researchers examined urine samples of subjects consuming a little less than a quarter cup of olive oil for three weeks. They were looking for specific compounds known to be waste by-products of oxidative damage to cells, a precursor to cancer. At the beginning of the trial the presence of these waste by-products was much higher in the Northern European subjects than their Southern European counterparts. By the end of three weeks of consuming the olive oil the presence of this compound in Northern European subjects was substantially reduced.

They also found that phenols in olive oil are not the only compounds that reduced oxidative damage. Phenols are a known antioxidant that is present in a wide range of foods, such as dark chocolate, red wine, tea, fruits and vegetables. Even if the level of phenols in the olive oil was reduced the study's subjects still received the same health benefits.

When you are cooking this holiday season, pick up some olive oil. I also use the spray olive oil which is great for getting those muffins out of the tray!

My little boys love candy -- and sometimes I think they eat healthy food only to earn sweets. Their constant badgering about candy has led to a recent ban on artificially-sweetened stuff in our house. If it's not in the house, they can't have it. No arguments. That's it. Fortunately, they also love fruit. So what we lack in candy we now make up for with fruit -- apples and bananas and grapes and peaches and strawberries are favorites. And just today at lunch, three-year-old Danny cleared his plate of strawberries and then proclaimed, "I love strawberries!" And I love that Danny loves strawberries -- especially in light of the news that hit papers today.

It seems that candy lovers are more likely than salt lovers to eat fruit. A study published in the journal Appetite found that people who eat candy, cakes, and other sweet snacks eat more fruit than people who prefer salty snacks like chips and nuts. Maybe that's the reason for my boys' equal affection for both candy and fruit -- and their indifference about salty treats. Apparently, the craving for something sweet is satisfied by both candy and fruit -- which is hopeful for kids whose parents might now steer them in the direction of the more healthy option. And for dieters who might incorporate more fruits into their menus in an effort to cut calories. And for anyone really who is concerned that a diet rich in candy, cookies, and cakes might contribute to illness and disease while fruits and vegetables encourage healthful living.

An apple a day.
