A food analysis device includes a variable wavelength interference filter adapted to disperse light reflected by the food into a plurality of lights with respective wavelengths, an imaging section adapted to image the lights with the respective wavelengths obtained by the dispersion to obtain spectral images corresponding respectively to the wavelengths, and a control section adapted to obtain spectrum of each of the pixels from the spectral images corresponding to the respective wavelengths, and then detect a pixel including the absorption spectrum of water, and then detect a plurality of components based on the spectrum of the pixel detected.
