The warm, toasted nuts airlines often serve to their first class customers may be doing more to help pampered passengers relax during flight than the cushy seats and fluffy pillows. Researchers at Penn State University found that regularly snacking on walnuts may help your body respond better to stress. Study participants who added a small daily dose of walnuts and walnut oil to their diet experienced a smaller rise in blood pressure during stressful events like giving an impromptu speech. Scientists speculate that the heart-healthy omega-3 fats
may be responsible for the nuts' calming benefits. Walnuts are great straight out of the package, but toasting them enhances the flavor and brings them to a whole new level. Simply arrange on a baking sheet and bake for 8 to 10 minutes in a 350 degree oven.
