A photographic method of diet evaluation.


A photographic method of diet assessment is described. The subject is issued with a camera and a food record book and asked to photograph all meals and record the number of the photograph and details which will not show in photographs such as the method of cooking, the use of sugar in drinks, etc. The photographs are viewed alongside previously prepared 'standard' slides which show the weights of a variety of portions of each foodstuff. A weight is given to each item and nutrient analysis is done with food composition tables. The cost of the camera is comparable to the cost of a weighing scale and the cost of film is about pounds 6 (+9) per subject per week.
