  Food recognition and nutritional apps are trending technologies that may
revolutionise the way people with diabetes manage their diet. Such apps can
monitor food intake as a digital diary and even employ artificial intelligence
to assess the diet automatically. Although these apps offer a promising
solution for managing diabetes, they are rarely used by patients. This chapter
aims to provide an in-depth assessment of the current status of apps for food
recognition and nutrition, to identify factors that may inhibit or facilitate
their use, while it is accompanied by an outline of relevant research and
development.
