Food of the Week: Walnuts

Food of the Week: Walnuts
Presented by Spartan Training®

Looking for more sources of plant-based omega-3 in your diet? When it comes to nuts, look no further than the historic walnut. In fact, the Romans and Greeks incorporated the walnut as part of their Mediterranean diet not only as a staple food, but for potential medicinal benefits as well.

It was once thought that walnuts mixed with certain foods and prepared in certain ways could even counteract poisons, remove bruises, cure dog bites, and grow hair. Although today’s medical needs differ, there’s no denying the outstanding benefits that these crunchy, fiber-filled, heart healthy, and versatile nuts offer.

Buying and Storing

Walnuts come in a variety of options such as in shell, shelled, whole, chopped, flavored, and raw. In-shell are most abundant in the fall, but walnuts can be found year-round at the grocery store either pre-packaged or in the bulk bins.

Believe it or not, walnuts are best kept in the fridge or freezer. Using them soon, go with the fridge. Keeping them on stand-by, opt for the freezer.

Walnuts have the tendency to absorb the aromas of other foods they are stored with, so avoid placing them in the fridge near onions, fish, or other strong odored foods.

Alternative use: Grind walnuts in a cool, dry food processor to make a walnut flour suitable for baking


The key to maintaining a nutritious diet for the long haul is crowding out the bad foods with the good. This takes a strong arsenal of nutrient-dense foods to keep you interested and coming back for more. The walnut’s versatility for use in breakfast recipes, salads, baked goods, protein toppers, and dessert make it a perfect fit for this goal. Just 1 oz of walnuts provides:

  • 18 grams of fat (15.5 of them from healthy unsaturated fats)
  • 4 grams of protein
  • 2 grams of fiber
  • 1 gram of natural sugar

They also contain the important minerals calcium, iron, and potassium while being a cholesterol and sodium free food. No wonder they earn the Heart Check Award from the American Heart Association!

Athlete Nutrition

The increased popularity of endurance events has peaked interest in understanding how to better fuel aerobic activity, which tends to require a larger percent of fuel from the macronutrient of fat vs the anaerobic drive to pull carbohydrates. The metabolic efficiency of the athlete is going to dictate which fuel source is most easily converted, and not everyone does well fueling with fats over carbohydrates. But for those interested in becoming more fat adapted, reducing carbohydrate intake, or looking to incorporate calorically dense fuel for an endurance event, nuts and nut butter can be a great option.

Walnuts are a great option since they contain the highest percent of Omega-3 alpha linolenic acid (ALA), an essential fatty acid which helps decrease inflammation, per one-ounce serving. Walnuts also provide phosphorus for energy production and magnesium to help regulate blood sugars.

Before you toss out all of your other nuts, remember that variety is the spice of life. Almonds, pistachios, macadamia nuts as well as others should still find space on your shelf.
