When it comes to apple juice, "cloudier" may mean healthier, according to a study published in January 2007, in the Journal of the Science of Food and Agriculture.
In a head-to-head comparison of apple juices, Polish researchers found that pulpy, non-clarified juice carried a greater antioxidant punch than clear juice. Antioxidants are compounds that neutralize free radicals, molecules that can damage body cells and contribute to disease.
Unlike cloudy apple juice, the much more common clear variety undergoes additional processing to remove any apple solids. Manufacturers typically think the public will favor the more attractive, clear juice over its cloudy cousin, and retailers prefer the clear variety for its longer shelf life.
But the new findings suggest that health-conscious consumers should reach for the cloudy variety, according to Dr. Jan Oszmianski, the study's lead author. "Cloudy apple juices contain much more antioxidant than clear," says Dr. Oszmianski, a researcher at the Agricultural University of Wroclaw.
In fact, Oszmianski's team found, cloudy juice packed up to four times the level of polyphenols, a group of antioxidant plant compounds. And in experiments, cloudy juice was the more effective free radical "scavenger," the researchers report in their findings.
In addition, Researchers at the University of California-Davis recently reported that apples and apple juice may help protect arteries from harmful plaque build-up. In the first study conducted in humans, adults who added two apples, or 12 ounces of 100% apple juice, to their daily diet demonstrated a significant slowing of the cholesterol oxidation process that leads to plaque build-up - thereby giving the body more time to rid itself of cholesterol before it can cause harm.
Enjoy some apples or cloudy apple juice each day and keep the doctor away!
