The Modesto Nuts, a minor league affiliate of Major League Baseball’s Seattle Mariners, adopted its name in 2005 to honor the almonds, walnuts, and pistachios that are grown near Modesto, Calif. The team mascots? Al the Almond, Wally the Walnut, and Shelley the Pistachio.

Those are potent choices. Spanish researchers have found that pistachios, almonds, walnuts, and hazelnuts can help undo the sex-stifling effects of an unhealthy Western diet (lots of sat-fat, few veggies) on men's libido.

In a study published in Nutrition, researchers tracked 83 relatively healthy guys (no diagnosis of erectile dysfunction) who were all eating poorly.

For 14 weeks, half of them added around 2 ounces of walnuts, almonds, and hazelnuts to their daily diet.

By the end of the study, those guys said they were newly charged up and raring to go.

In a previous study, the same researchers found that 3.5 ounces of pistachios daily help ease diagnosed erectile dysfunction.

Sexual dysfunction affects around 52% of guys ages 40 to 70, and 85% over age 80. But it isn't inevitable; it's the result of smoking, excess alcohol, lack of activity, stress, and bad diet, among other things.

So if your libido is lagging or you're struggling with erectile dysfunction, talk to your doctor to make sure chronic health problems aren't the cause.

Then strengthen your lineup of foods by ditching red and processed meats, and opting for 100% whole grains and seven to nine servings a day of fresh produce to go along with your daily, libido-raising, almond, walnut, hazelnut, and pistachio snacking.
