As far as I know, this code should be used to generate a nutrition label based on a given amount of a specific food:

EntityInstance[refried beans, 200g]["NutritionLabel"]

I tried to include this option in the FormFunction function so that on a website generated with the Wolfram Language, nutrition labels could be displayed by searching for a specific food name with this code:

CloudDeploy[FormFunction[{"Food"->"Food"},{"Gram"-"Quantity"},
#Food["NutritionLabel"]#Gram["NutritionLabel"]&]]. 

Unfortunately, this doesn't work. How could this be solved? Thank you in advance for your help.
