A nutrition recommendation system is a technology that uses personal and contextual data to provide individuals with personalised nutrition advice. These systems are designed to improve health outcomes by helping individuals make informed food choices that align with their specific dietary needs and preferences.

The use of nutrition recommendation systems has been shown to have a positive impact on health outcomes, including weight loss and improved blood sugar control. However, there are still challenges to be addressed in the development of these systems, including the need for more accurate and reliable data inputs, as well as the need for more user-friendly interfaces that can be easily integrated into daily life.
