Claim Text:
1. A system for measuring nutritional parameters of food items, the system comprising: a holding cavity; a sensor assembly comprising a transmitter antenna and at least one receiver antenna, wherein the transmitter antenna is configured to transmit signals to at least a portion of a food item disposed in the holding cavity, and wherein the at least one receiver antenna is configured to receive response signals from the food item; at least one switch coupled to each antenna of the sensor assembly; wherein, in a first state, the at least one switch is configured to set the sensor assembly to an electric potential equal to that of the holding cavity in order to limit interaction between electromagnetic waves in the holding cavity and the sensor assembly; and, in a second state, the at least one switch is configured to couple the sensor assembly to a power source during operation of the sensor assembly to determine the nutritional parameters of the food item; and a processing unit configured to process the signals received by the receiver antenna to determine the nutritional parameters of the food item.
