1. A food processing device or food storage device, comprising:
a chamber for housing a foodstuff to be processed or stored; and
a nutrition analysis system, comprising:
an electromagnetic radiation source;
a radiation guide for guiding electromagnetic radiation based on total internal reflection, wherein the radiation guide comprises an input coupled to the electromagnetic radiation source, an output, and a sensing surface between the input and the output for placing against the foodstuff to be analyzed, wherein the sensing surface is for contact with the foodstuff;
a detector for detecting guided electromagnetic radiation at the output of the radiation guide; and
a filter arrangement for wavelength filtering the guided electromagnetic radiation reaching the detector, wherein the filter arrangement comprises a plurality of optical bandpass filters, and wherein the plurality of optical bandpass filters are selectively movable into a path of the detector.
