In the last decade, developed and developing countries have unsuccessfully been fighting the so called new world syndrome or the epidemic of 21st century. Nutritional misbehaviors in so called developed countries are causing significant social and economic damages, reflected in considerable growth of chronic diseases, morbidity and death. The phenomenon has been traditionally felt in aged populations, but a significant increase has also been detected more recently in young populations. This chapter presents a proposal to tackle theses serious problems related to nutrition by the means of information and communication technology tools. NutriMe is presented as a new nutritional monitoring and advising system to help individuals to monitor and correct their behaviors. NutriMe is also proposed as the main component for a public national observatory on nutritional profiles for public health and medical analysis purposes.
