The Walnut Marketing Board created the first National Walnut Day in June of 1949 to celebrate and promote the consumption of walnuts. Then, on March 3, 1958, President Dwight D. Eisenhower declared that May 17, 1958, would be National Walnut Day. You may or may not be aware, but walnuts provide many health benefits and can be used in so many ways. Sometimes we may eat walnuts as a snack and other times we may use them in desserts and salads.
