Health literacy has emerged as a focus of increasing research in the medical literature, yet it has received little attention in the nutrition literature. Because nutrition practice is an important sector of the health care environment and reduced health literacy confers known health consequences, dietitians should be equipped with an understanding of how health literacy extends to nutritional care. Identification instruments that are available fail to provide an understanding of nutrition literacy. Nutrition literacy may include knowledge of nutrition principles and nutrition skills. Additional research into the development of appropriate nutrition literacy tools and their application is needed.
