Description of a food recording electronic device for use in dietary surveys

A Food Recording Electronic Device has been developed for quantitative collection of dietary data in the home for a period of up to 3 weeks. The accumulated information on the weights and types of food, and time of consumption, is transferred to a host computer for calculation of the nutrient composition of the diet. Using this method the subject does not have to read the balance or keep a written diary, and the need for coding of records by a dietitian is eliminated.
