[Health] Feature to add nutrition data values

[mikenussbaumer]

Description

For iOS, there is a section for nutrition type identifiers. So as developers we can track nutrition types that the user consumes. For example calories, protein, carbs, fats...

See the full list of identifiers here: https://developer.apple.com/documentation/healthkit/data_types/nutrition_type_identifiers

This would be a great feature for every app that has some kind of food-related data!
