USDA Nutrient Database

The USDA nutrition database is a great source of nutrition information. However, the data formatting options (plain text ASCII files or MS-Access) leave a little to be desired.

This is a simple gem to import the database into your ruby application.

Installation

Add this line to your application's Gemfile:

gem 'usda-nutrient-database'

And then execute:

$ bundle

Or install it yourself as:

$ gem install usda-nutrient-database

If you're using rails then copy the migrations across:

rake usda_nutrient_database_engine:install:migrations

Usage

Import the latest data with the import task:

rake usda:import

This is going to take a while. 60+ minutes on my 2.66 GHz i7 macbook pro

Use the models to query and profit:

UsdaNutrientDatabase::FoodGroup
UsdaNutrientDatabase::Food
UsedNutrientDatabase::Nutrient
UsdaNutrientDatabase::FoodsNutrient
