Walnut: King of Nut Antioxidants?

Walnuts have more antioxidants-and more potent ones-than any other nut, according to research presented at the National Meeting & Exposition of the American Chemical Society on March 27.

Walnuts have more antioxidants-and more potent ones-than any other nut, according to research presented at the National Meeting & Exposition of the American Chemical Society on March 27.

“Walnuts rank above peanuts, almonds, pecans, pistachios and other nuts,” said lead researcher Joe Vinson, PhD of the University of Scranton, Pennsylvania. “A handful of walnuts contains almost twice as much antioxidants as an equivalent amount of any other commonly consumed nut.”

Vinson and his research team compared the antioxidant quality of various types of nuts-walnuts, almonds, peanuts, pistachios, hazelnuts, Brazil nuts, cashews, macadamias, and pecans-to find that walnuts had the highest levels. Walnuts offered the highest amount of antioxidants and also the highest potency on antioxidants­-two to fifteen times as potent as those in vitamin E, according to Vinson.

This news can only do good for nuts, which Vinson says make up just 8% of the average person’s daily antioxidant intake.
