Raw walnuts contain antioxidants.They also contain triglycerides of the n-3 fatty acid alpha-linolenic acid which is effective in reducing heart risk. There’s one more thing. Important research shows that walnuts may prevent Alzheimer’s disease.
Walnuts are top nut for heart-healthy antioxidants. Compared to other tree nuts and ground nuts (almonds, peanuts and hazelnuts, pistachios, Brazil nuts, cashews, macadamias, and pecans), walnuts (particularly in their raw form) contain the highest level and potency of antioxidants, including free antioxidants and antioxidants bound to fiber.
“Walnuts rank above peanuts, almonds, pecans, pistachios and other nuts,” said Joe Vinson, Ph.D., who did the analysis. “A handful of walnuts contains almost twice as much antioxidants as an equivalent amount of any other commonly consumed nut. But unfortunately, people don’t eat a lot of them. This study suggests that consumers should eat more walnuts as part of a healthy diet.”
