Health secrets of walnuts

The festive season may be over, but there is at least one Christmas treat worth making a  habit of eating throughout the year – walnuts. Scientists have discovered they are the healthiest nuts to eat as they are loaded with antioxidants.
Snacking on as few as seven a day could help ward off disease and lower cholesterol, they claim. Walnuts contain very high levels of polyphenol, an anti-oxidant which can protect the body from molecules which damage tissue.
Walnuts contained the most polyphenol out of a list of nine commonly eaten types of nuts, tests revealed. Brazil nuts and pistachios were close behind, and cashews and hazelnuts had slightly lower levels of antioxidants.
