Usage

NutrientKit (NutrientKit.framework) integrates with the USDA National Nutrient Database for Standard Reference via the USDA NDB API. Food composition data is in the public domain, there is no copyright and no permission is needed for its use.

To use NutrientKit in your app, you'll need to sign up for a Data.gov API key.

Nutrient Store

First, create a NutrientStore with your API key:

let nutrientStore = NutrientStore(apiKey: "YOUR_API_KEY")

Search

A search request sends keyword queries and returns lists of foods which contain one or more of the keywords in the food description, scientific name, or commerical name fields.

let query = "Cheddar cheese"
    
nutrientStore.search(withQuery: query, dataSource: . standardReference) { page, error in
	// Reload the list of search items.
}

Food Reports

A food report is a list of nutrients and their values in various portions for a specific food.

let ndbno = "01009" // Cheese, cheddar

nutrientStore.basicReport(forNDBno: ndbno) { report, error in
    // Present the food report.
}
