It would be great if there was a list off all the lables we could use in our filters, without haveing to make a list myself by going through hundrends of results and just writing down what I find.

From looking through articles, this is the most I could find out.

healthlabels This array contains the health label for the selected recipe, such as ‘peanut-free’, ‘gluten-free’ etc.

cautions This variable contains if the recipe has any allergen warning"
