Fisher Chef's Naturals Black Walnuts comes in a 2 ounce pack. As the oldest-known tree food eaten by man, walnuts are used today more than any other nut in America’s home-cooked recipes and restaurant dishes. Originating in ancient Persia about 7, 000 B. C., walnuts were first traded along the Mediterranean by English merchant ships. This fact may be the reason for the misleading name English Walnuts, since walnuts were never produced in England commercially. Today California produces 70 percent of the world’s walnuts, thanks to some Franciscan fathers from Mexico and Spain who introduced the trees to the area in the late 1700s. At John B. Sanfilippo and Son, Inc. (JBSS), parent company of the Fisher brand, we pride ourselves on knowing everything there is to know about nuts. When it comes to smarter snacking, better baking and great cooking, JBSS and our Fisher brand are your natural choice for nuts you can feel good about. Scientific evidence suggests that eating 1.5 ounces per day of most nuts, such as peanuts, almonds, hazelnuts, pecans, pistachio nuts and walnuts, as part of a diet low in saturated fat and cholesterol may reduce the risk of heart disease.
