Cancer Prevention
The antioxidants in nuts help fight free radicals that can damage cells and lead to cancer. Walnuts may offer added protection due to their melatonin content.
Brain Health
Walnuts contain omega-3s that support cognitive function. Cashews provide magnesium that helps reduce migraine frequency.
Skin Health
Cashews and walnuts help nourish the skin from within thanks to their fatty acids, vitamins, and antioxidants.
Male Fertility
A handful of walnuts a day may improve sperm quality due to the omega-3 content. More research is needed.
Bone Health
Magnesium in cashews and manganese in walnuts helps promote bone formation and strength.
Vision Protection
Vitamin E and zeaxanthin in walnuts support eye health. Lutein in cashews also benefits vision.
Digestion
Walnuts are high in fiber which aids digestion. But cashews may be better for people with IBS due to their lower fiber.
