According to the World Health Organization around 80% of cases of heart disease, strokes and type 2 diabetes could be avoided if people were to implement a healthier diet. Computational data analytics approaches have been touted as a valuable asset in achieving the ambitious goal of understanding user behavior and being able to develop intelligent online systems, which can positively influence people’s food choices.

At this talk you will hear about:

data science approaches to understand, predict and potentially change food decision making in an online context,
what extent online food interactions can be linked to real-world health issues such as obesity on a large-scale,
how people upload, bookmark or rate online recipes in large online food communities
and how contextual factors and biases such as seasonality, temporality, social context or presentation of recipes have an impact on popularity and how they are perceived.

With this background we can model and predict the users’ online food choices and attempt to nudge people towards food choices.
