This nutrient-rich snack is more than just a way to fight heart disease and ward off ******* (though, yes, those are obviously big perks, too). As it turns out, they are a nutritional powerhouse that supports healthy aging more than any other nut.

, walnuts are also a good source of heart-healthy fats, are high in fiber, filled with micronutrients, and packed with antioxidants that support our overall health and wellbeing, registered dietitian Melissa Jaeger tells Delish. While all nuts contain healthy fats, walnuts are particularly rich in polyunsaturated fats, especially omega-3 fatty acids, and they are the only nuts that contain significant amounts of the healthy omega-3 ****

“A one ounce serving of walnuts provides valuable nutrients such as protein, fiber, and magnesium,” Jaeger, who is an in-house nutritionist for MyFitnessPal, continues. “Their heart health benefits are further highlighted by their certification with the

What Role Do Walnuts Play In Anti-Aging?

According to fellow in-house RD at MyFitnessPal, Joanna Gregg, all of these nutrients make walnuts an incredible resource in anti-aging from the inside out.

“Walnuts contain multiple components such as fatty acids, fiber and essential vitamins and minerals that have antioxidant and anti-inflammatory effects in the body,” Gregg tells Delish. She points to multiple

supports these findings and in fact suggests that walnuts are uniquely linked to healthy aging among nuts. The researchers followed 33,931 women in their late 50s and early 60s, assessing their diets, physical health, memory, and chronic disease status.

Ultimately, the study found that women who consumed at least two servings of walnuts per week had 20% higher odds of being classified as “healthy agers” compared to those who did not eat walnuts. Healthy agers were defined as those with sound mental health, no major chronic diseases or memory issues, and no physical disabilities—a category that comprised about 16% of the participants. While initial analysis showed a link between total nut consumption and healthy aging, after adjusting for various factors, only walnuts maintained a significant association.

Jaeger recommends opting for raw, dry roasted, or unsalted nuts to reduce added salt or sugar. “For a more satisfying snack, you can roast raw nuts at home tossed in your favorite spices,” she suggests.
