I wrote an R package called nutritionR that interfaces with the /v2/natural/nutrients endpoint. Using this package, you can query Nutritionix API and extract the sum total for any one of 68 nutrients.

For example, let’s say you wanted to know how many calories were in your query “A hamburger with cheese”. You can do this with two of the package functions:

obj <- nutritionix_lookup(“A hamburger with cheese”)
nutrient(obj, “calories”)
