Raw foodism (or rawism) is a lifestyle promoting the consumption of un-cooked, un-processed, and often organic foods as a large percentage of the diet. If 100% of a person's total food consumption is raw food, he/she is considered a raw foodist or living foodist. Raw foodists typically believe that the greater the percentage of raw food in the diet, the greater the health benefits. Raw foodism or a raw diet is usually equated with raw veganism in which only raw plant foods are eaten, but other raw foodists emphasize raw meat and other raw animal products. Depending on the type of lifestyle and results desired, raw food diets may include a selectıon of raw fruits, vegetables, nuts, seeds (including sprouted whole grains such as gaba rice), eggs, fish (such as sashimi), meat (such as carpaccio), and non-pasteurized/non-homogenized dairy products (such as raw milk, raw milk cheese, and raw milk yogurt). Raw foodists can be divided between those that advocate raw vegetarianism or raw veganism, those that advocate a raw omnivorous diet, and those that advocate a diet of only raw animal foods (carnivorous).

Adherents of raw foodism believe that consumption of uncooked foods encourages weight loss (and stability, without the risk of re-gaining), while also preventing and/or healing many forms of sickness and chronic diseases. Some medical studies have indicated that different forms of raw food diets may lead to various health problems, while other studies have shown positive health outcomes with such diets.
