The tracking of nutrients in aliments is a key aspect to consider when dealing with several pathologies. A clear example is type-1 diabetes: people diagnosed with this disease need to administrate insulin injections on daily basis. The estimation of the prandial dose is complex, time consuming and depends on several factors. Studies demonstrated that even well-trained patients, tent to over/underestimate CHO by 27% on average on every meal. Moreover, especially for early diagnosed people with little to none training, it could be hard to keep track of the CHO contained in each food, especially when they go eating outside. Type 1 diabetics are not the only patients that suffer the disadvantages and the complexity of their treatments.
