Peanut butter is a popular food paste made primarily from ground dry roasted peanuts that is mainly used as a sandwich spread, sometimes in combination with other spreads such as in the peanut butter and jelly sandwich. The United States and China are leading exporters of peanut butter. Other nuts are used as the basis for similar nut butters.
Peanuts are native to the tropics of the Americas and were mashed to become a pasty substance by the Aztec Native Americans hundreds of years ago. Early forms of peanut butter, like the Aztecs’ version, were nothing but a paste made from roasted peanuts. Modern processing machines allow for very smooth products to be made, which often include vegetable oils to aid in its spreadability.
Evidence of peanut butter as it is known today comes from U.S. Patent 306,727, issued in 1884 to Marcellus Gilmore Edson of Montreal, Quebec, Canada, for the finished product of the process of milling roasted peanuts between heated surfaces until the peanuts entered “a fluid or semi-fluid state.” As the peanut product cooled, it set into what Edson explained as being “a consistency like that of butter, lard, or ointment”. Edson’s patent is based on the preparation of a peanut paste as an intermediate to the production the modern product we know as peanut butter; it does show the initial steps necessary for the production of peanut butter.
Dr. John Harvey Kellogg patented a “Process of Preparing Nut Meal” in 1895 and used peanuts. Kellogg served peanut butter to the patients at his Battle Creek Sanitarium. Dr. Ambrose Straub, a physician in St. Louis, Missouri, pursued a method for providing toothless elderly with protein in the 1890s. His peanut-butter-making machine was patented in 1903.
Peanut butter has a high level of monounsaturated fats and resveratrol. Peanut butter (and peanuts) provides protein, vitamins B3 and E, magnesium, folate, dietary fiber, arginine, and high levels of the antioxidant p-coumaric acid. For people with a peanut allergy, peanut butter can cause reactions, including anaphylactic shock, which has led to its being banned in some schools.
Some brands of peanut butter may contain a small amount of added partially hydrogenated vegetable oils, which are high in trans fatty acids that are thought to be a cause of atherosclerosis, coronary heart disease, and stroke; these oils are added to prevent the peanut oil from separating from the ground peanuts. Peanuts and natural peanut butter, i.e., ground, dry roasted peanuts without added oils, do not contain partially hydrogenated oils or trans fats.
