It sounds nutty, but May 17th is National Walnut Day.
Created to promote the consumption of walnuts, the first National Walnut Day was proclaimed in June 1949 by the Walnut Marketing Board.
On March 3, 1958, a Senate Resolution was introduced by William F. Knowland and signed by President Dwight D. Eisenhower on the first National Walnut Day, May 17, 1958.
Walnuts are a high-density source of nutrients, particularly proteins and essential fatty acids. Like other tree nuts, walnuts must be processed and stored properly.
Grown for their seeds, the Persian or English Walnut and the Black Walnut are the two most common major species of walnuts.
