Walnuts are considered one of the oldest tree foods known to humans, with a history stretching back thousands of years. Early on, people discovered that walnuts were easy to store, simple to eat, and highly nutritious.
In ancient Persia, walnuts were known as the Royal Nut and were reserved for royalty. During the time of Alexander the Great, walnuts were brought from Persia to Greece and were called Persian nuts for over a thousand years. Over time, Greek-grown walnuts became smaller and less desirable, leading to efforts to improve them by reintroducing Persian varieties.
The Greek word for walnut is karyon, meaning head, which is fitting since the shell resembles a human head and the inside looks similar to a brain.
Walnuts likely spread into Europe between 500–700 BC and later reached the British Isles through the Roman Empire. Around this time, the name “English walnut” emerged to distinguish it from black walnuts.
Eventually, walnuts made their way to the New World. Franciscan missionaries found that Southern California provided ideal growing conditions, which led to the name “mission walnuts.” Today, California produces about 99% of the walnuts in the United States and plays a major role in global supply.
National Walnut Day has been celebrated for over 70 years. It was established in 1949 by the Walnut Marketing Board in the United States to promote this nutritious food. In 1958, President Dwight D. Eisenhower officially recognized it as a public holiday, and it continues to be celebrated annually.
The walnut’s long journey explains why it appears in so many cuisines. Its ability to store well and its protective shell made it ideal for travel and trade. It also provided a valuable source of energy through fats and protein.
Walnut trees themselves require patience. They take time to mature but can produce generously once established. Cultivation became closely linked to land management and seasonal harvest practices. After harvesting, walnuts are hulled and dried to ensure proper storage and prevent spoilage.
The term “English walnut” can be misleading, as it does not indicate origin but rather distinguishes it from black walnut varieties. Black walnuts have a stronger flavor and tougher shell, while English (or Persian) walnuts are milder and easier to use in cooking.
National Walnut Day began as a way to highlight the walnut’s importance as both a crop and a food. Over time, it has become a simple reminder to cook, bake, and enjoy walnuts while appreciating their long history and versatility.
Learn Some Health Benefits of Walnuts
National Walnut Day is a great opportunity to get to know the health benefits packed into this small but powerful nut. Here are a few reasons why walnuts make a smart choice for both snacking and baking: Filled with Antioxidants Walnuts are highly valued for their rich antioxidant content, including compounds like polyphenols and vitamin E. Antioxidants are important because daily life creates oxidative stress in the body, and diets that include antioxidant-rich foods are often linked to better overall wellness. What makes walnuts stand out is that these compounds are not only inside the nut but also concentrated in the thin, papery skin. That slight bitterness you may notice comes from that layer, which is also why it’s worth keeping it on instead of removing it. High in Healthy Fat Walnuts are especially known for their omega-3 fats, including ALA (alpha-linolenic acid), which is considered essential because the body cannot produce it on its own. This is particularly useful for people who do not regularly eat fish, as walnuts are one of the most recognizable plant-based sources of omega-3s. Their fat content also makes them satisfying, adding richness to meals whether they are sprinkled over vegetables or blended into sauces. Promotes Gut Health Walnuts contain fiber and plant compounds that support a healthy digestive system. Gut health goes beyond regular digestion. The gut microbiome plays a role in metabolism, digestion, and many other bodily functions. Walnuts provide a combination of fiber and natural compounds that nourish beneficial gut bacteria. Adding them to your routine is a simple way to increase plant diversity in your diet, which is often encouraged for overall digestive wellness. May Decrease Inflammation Inflammation is a natural response in the body, but long-term inflammation is linked to various health concerns. Walnuts provide nutrients commonly associated with supporting a balanced inflammatory response, such as polyphenols and omega-3 fats. While no single food can do everything, walnuts fit well into balanced eating patterns that focus on whole foods and healthy fats.
Make Some Candied Walnuts
While candied pecans and toasted almonds often get the spotlight, candied walnuts are definitely worth trying. They make a delicious snack, a great salad topping, or a finishing touch for cakes and desserts. Plus, they are incredibly easy to prepare. All you need are three ingredients: walnuts, butter, and sugar. Add everything to a skillet and heat over medium heat for about five minutes, stirring constantly. Then spread the nuts on parchment paper and let them cool. For better results, small adjustments can make a big difference. Use medium heat instead of high so the sugar melts evenly without burning. Stir continuously and watch closely, because once sugar heats up, it can quickly go from perfect to overdone. Spreading the walnuts out to cool is important, as they set quickly and can stick together if left in a pile. These three ingredients are the classic base, but walnuts pair well with added flavors. A pinch of salt enhances sweetness. Cinnamon creates a warm, bakery-style taste. A bit of chili powder or cayenne adds a sweet-and-spicy twist that works surprisingly well with roasted vegetables. Vanilla or a touch of maple syrup can deepen the flavor with a caramel-like note. Candied walnuts are not just for desserts. They work beautifully on salads with bitter greens, paired with fruit, or added to sandwiches with sharp cheese. They can also be crushed and used as a crunchy topping for ice cream, yogurt, or oatmeal.
