Food Nutrient Database
The U.S. Department of Agriculture provides a fantastic resource for food nutrition data. The formatting however leaves a lot to be desired:

Food's an interesting subject, and I've had quite a few itches in the past to create food related web apps. But I was always quickly put off after remembering the state of the data I first had to deal with. Until today.
There's a lot of data included which, quite frankly, doesn't seem very useful (e.g. nutrient "22:1 undifferentiated", whatever that is.) So I've cherry-picked the good stuff, and dumped it as JSON goodness.
Example record:
Notes
- 6,636 unique foods.
- 375,176 nutrient figures, avg. 56.5 per food.
- Foods from the original database without any recorded nutrients have been removed.
- Nutrients still being researched and without proper names have been removed, e.g. the "22:1 undifferentiated" one.
- The
tagsare commonly used words to describe the food, including regional names. For example, "soda" or "pop" for carbonated beverages. - The format of the
idfield in the original database was a 5-digit string (i.e. "001001".) I've converted this to an integer here,1001, so bare this in mind if you're comparing against other USDA related resources using the original format. - 94 unique nutrients across all foods:
