I built a FoCo (Dartmouth's dining hall) nutrition scraper API app that lets you query by year / month / day and returns a JSON listing of food offered in the dining hall that day, with associated nutrition facts for every single food item.
Integrated this with a mobile app that lets me create my own "food diary" application. I can enter in my food portions and calculate exactly how much macronutrients I'm taking in.
Eventually, we plan to merge this in with Timely as a zero-action feature. Imagine walking into FoCo and Timely pulls up the food offered that day with the associated nutrition facts seamlessly and automatically.
