One of the harder data sets to track is food consumption, which can in theory provide some vague estimate count of nutrient, calorie, etc. over time. Once tracking this data becomes easier, we can start to correlate this against health outcomes.
I’ve come across two approaches recently, both of which seem impressive when looking at the demo:
- Evolve does this by allowing you to speak to it. I assume they will create Alexa, Google Home, etc apps. Check out the video: https://vimeo.com/221845678
- Bitesnap does this by allowing you to take photos: https://www.youtube.com/watch?v=Uw6kjbiFcNs
In both cases, the app will parse out your food input into ingredients, then nutrients. Both (I assume) will learn over time and get better at knowing what you eat. Bitesnap seems to have a more intuitive way to provide feedback.
