Nutrition Intake and Emotions Logging System

Unbalanced diet is a major risk for chronic diseases such as cardiovascular, metabolic, kidney, cancer, and neurodegenerative diseases. Current methods to capture dietary intakes may include food-frequency questionnaires, 7-day food records and 24 h recall. These methods are expensive to conduct, cumbersome for participants, and prone to reporting errors. This chapter discusses the development of a Personal Nutrition Intake and Emotions logging system. The following will be discussed: establishing requirements and designing a simple interactive system, implementing a simple interactive system, performing data analysis, and evaluation of the simple interactive system.
