Diet has a major influence on both, human health and their behavior. Raw veganism is a diet that brings together two concepts: the one of veganism and the one of raw foodism, a diet that excludes all ASF (Animal Source Foods), all food cooked at a temperature above 48 °C (118 °F), and any food that is changed from its ordinary condition, and/or processed. The aim of the study was to bring more information about raw vegan diet and the controversy raw vegan versus cooked food. Scientific data taken into account recommend the use of the raw vegan diet mostly for a short period.
