All new patients seen at The Center must complete a nutrition evaluation questionnaire as part of their application packet. This questionnaire is the Sherlock Questionnaire containing 318 different food and drink items. For seven days, the patient, or parent in case of children, places a mark beside each serving of food or drink consumed. Blank spaces are available to write in any items not listed on the questionnaire. The information is entered into a computer program which calculates the percentage of the RDA from selected nutrients and prints out a nutrition evaluation summary.
