National Nut Day is observed worldwide every October 22 and celebrates the health benefits of nuts. This food holiday, which is well-established in the United States and has gained popularity in the UK, encourages people to recognize the nutritional value of various nuts. While the botanical definition of a nut is specific, the culinary interpretation includes a broader range of seeds and fruits, such as almonds, cashews, and walnuts. Nuts are known for being high in nutrients, including fat, protein, vitamins, and fiber, making them a popular choice in vegetarian cuisine and a healthy snack option. To celebrate National Nut Day, individuals are encouraged to substitute nuts for their usual snacks, highlighting their taste and health benefits.
