Query: Investigating Health-Aware Smart-Nudging with Machine Learning to Help
  People Pursue Healthier Eating-Habits   Food-choices and eating-habits directly contribute to our long-term health.
This makes the food recommender system a potential tool to address the global
crisis of obesity and malnutrition. Over the past decade,
artificial-intelligence and medical researchers became more invested in
researching tools that can guide and help people make healthy and thoughtful
decisions around food and diet. In many typical (Recommender System) RS
domains, smart nudges have been proven effective in shaping users' consumption
patterns. In recent years, knowledgeable nudging and incentifying choices
started getting attention in the food domain as well. To develop smart nudging
for promoting healthier food choices, we combined Machine Learning and RS
technology with food-healthiness guidelines from recognized health
organizations, such as the World Health Organization, Food Standards Agency,
and the National Health Service United Kingdom. In this paper, we discuss our
research on, persuasive visualization for making users aware of the healthiness
of the recommended recipes. Here, we propose three novel nudging technology,
the WHO-BubbleSlider, the FSA-ColorCoading, and the DRCI-MLCP, that encourage
users to choose healthier recipes. We also propose a Topic Modeling based
portion-size recommendation algorithm. To evaluate our proposed smart-nudges,
we conducted an online user study with 96 participants and 92250 recipes.
Results showed that, during the food decision-making process, appropriate
healthiness cues make users more likely to click, browse, and choose healthier
recipes over less healthy ones.
