Mobile and social technologies can help encourage healthy eating habits by increasing awareness of healthy foods and making it easier to share cooking experiences. Apps like Yelp, Locavore, and DinnerSpinner increase the availability of information about healthy food options nearby. Flickr and Facebook provide motivation to cook and eat healthy foods by allowing people to share photos of meals with friends. While these tools focus on availability, more can be done to motivate healthy choices when eating out and cooking at home.
