You’d never suspect it to look at them, but walnuts are one of the most important sources of plant chemicals known as polyphenols which studies have linked to reducing the risk of diseases as diverse as cancer, heart disease and Alzheimer’s.
Another study confirmed that walnuts rank above all other nuts, including almonds, pecans and peanuts, in their abundance of antioxidants including polyphenols. In fact, they have twice as many of these disease-fighting chemicals as any other nut, according to the research, which was presented at a meeting of the American Chemical Society.

And their brain-like shape is, ironically, a clue to something else they do. Researchers at the David Geffen Medical School at the University of California at Los Angeles, in a study published in the Journal of Nutrition Health and Aging, found that those who eat 10.3 grams of walnuts daily—that’s just six to seven walnut halves—did better than people who didn’t eat walnuts on tests measuring memory, concentration and information processing speed.
And if that’s not enough, walnuts are a good source of linolenic acid, an omega-3 fatty acid linked to heart health, and they have an unusually high amount of vitamin E, according to a study published in 2009 in the journal Acta Horticulturae, which also found that walnut consumption contributed to weight loss, lower cholesterol and blood sugar control in type 2 diabetes.
