The chemical composition of their diets was evaluated with computer, taking into consideration the losses during food preparing, and compared with the diets recommended. Certain variations in the chemical formula of the patients' home diets were revealed using this method. It is stressed that the dietetic recommendations given to coronary patients should be followed, while their physicians should thoroughly control their adherence to the diet.
