Nutrition Intake observables

Current template, still in process is located here: A nutritional intake (observable entity) - v1.0

Questions:

Using attribute "Process output" seems incorrect for intake
Create a sub-hierarchy << 788335003 |Intake process (qualifier value)| but it is duplicating our "route" hierarchy, is there a better solution?

A few examples being requested, unclear on how/if we can model:

Fasting pattern in one calendar day (observable entity) - also requesting same for "one calendar week", "one calendar month", "one calendar year".

Estimated fruit servings in 24 hours (observable entity)| - in number per day, what to do with servings:

Substance questions

784184006 |Estimated oral fluid intake in 24 hours (observable entity)| - no substance of "fluid"?
Estimated total intake of fluid from food (observable entity) - "fluid from food"?
Intake of enriched food (observable entity) also requesting same for "fortified food", "special dietary food", "medical food", "processed food", "quick service food", "self prepared food", "prepared food"
Measured number of snacks in 24 hours (observable entity) - "snacks" is there an international definition?
100% fruit juice - concentration - (https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/CFRSearch.cfm?fr=101.30)
