Nutrition Intake observables

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

Example:

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)
