Huckleberry imports a curated version of the USDA's nutritional datasets for use in nutrition apps. While the USDA's datasets are great for research purposes, we've reorganized, recalculated, and developed methods to enable easy access to the most useful data for developers of nutrition apps, such as meal planners, recipe aggregators, and other applications.
Thank you to Matt Beedle and his USDA Nutrient Database for some of the code underlying this project and to the USDA for providing free data!
Add this line to your application's Gemfile:
gem 'huckleberry'And then execute:
$ bundle
Or install it yourself as:
$ gem install huckleberry
Install the necessary migrations by running:
$ rake huckleberry_engine:install:migrations
And then migrate the database:
$ rake db:migrate
Import nutritional data using the import task:
$ rake huckleberry:import
Note: The USDA's datasets contain hundreds of thousands of records, which means that this process may take some time.
The data can then be accessed in an ingredients model, for example:
Huckleberry::Ingredient
Huckleberry::Ingredient.total_calories
Huckleberry::Ingredient.saturated_fat
Huckleberry::Ingredient.fructose
Huckleberry::Ingredients.selenium
