Dietary factors have long been considered to influence the formation of cholesterol gallstones. A number of clinical and epidemiological studies have demonstrated, although with inconsistent results, the possible impact of dietary factors such as high energy intake, high intake of cholesterol and fat (especially polyunsaturated fatty acids), high intake of refined carbohydrates, and low intake of dietary fiber.
