The Western pattern diet (WPD) is a modern dietary pattern that is generally characterized by high intakes of red meat, processed meat, pre-packaged foods, butter, candy and sweets, fried foods, conventionally-raised animal products, high-fat dairy products, eggs, refined grains, potatoes, corn (and high-fructose corn syrup) and high-sugar drinks, and low intakes of fruits, vegetables, whole grains, pasture-raised animal products, fish, nuts, and seeds. The modern standard American diet was brought about by fundamental lifestyle changes following the Neolithic Revolution, and, later, the Industrial Revolution.
