Eat cranberries, shoo away health woes

Scientsists are also investigating the potential of the fruit against cancer, stroke and viral infections.

Cranberries are among the top foods with proven health benefits, according to Amy Howell, a researcher at Rutgers University. Cranberries are full of antioxidants, which protects cells from damage by unstable molecules called free radicals.

The National Institute of Health, USA, is funding research on the cranberry’s effects on heart disease, yeast infections and other conditions, and other researchers are investigating its potential against cancer, stroke and viral infections.

So far research has found:
Drinking cranberry juice can block urinary infections by binding to bacteria so they can’t adhere to cell walls. While women often drink unsweetened cranberry juice to treat an infection, there’s no hard evidence that works.

Fruit for all seasons

A compound Howell discovered in cranberries, proanthocyanidine, prevents plaque formation on teeth; mouthwashes containing it are being developed to prevent periodontal disease.

In some people, regular cranberry juice consumption for months can kill the H pylori bacteria, which can cause stomach cancer and ulcers.

Preliminary research also shows:

Drinking cranberry juice daily may increase levels of HDL, or good cholesterol and reduce levels of LDL, or bad cholesterol.

Cranberries may prevent tumours from growing rapidly or starting in the first place.

Extracts of chemicals in cranberries prevent breast cancer cells from multiplying in a test tube; whether that would work in women is unknown.
