Testing apparatus and methods eliminate uncertainties associated with applied kinesiology (AK) evaluation. The invention comprises a housing and a vertical member extending upwardly from the housing. The member includes an upper platform to receive a pressure-applying body part and a lower portion that enters into the housing wherein it is coupled to a device to measure the applied pressure. The measurement device is in communication with a readout on the housing that indicates the applied pressure. The platform, preferably in the form of a cradle, is coupled to a receptacle to hold a food or item to be evaluated. The patient applies a standard measured resistance, and when the item to be tested is held by the patient, the machine measures the decrease in resistance from the body, thereby accurately quantifying the patients response to the food or other item being tested.
