Is there a word that best describes food and drink taken at the same time? I've thought of refreshments and consumables but neither seem right to me.
Sustenance refers to food and drink.
According to US Legal, aliments are food or drinks that can provide nourishment and support life.
Apparently in the legal context they may also include clothing, but this was news to me.
In my opinion, it depends on what other things you might want to connote. For example, refreshments is a great word for food and drink together - especially food and drink at group functions like meetings and parties.
"I look forward to seeing you at the all-hands meeting. Don't forget that refreshments will be provided."
If you are talking about procuring food and drink together, you might call them groceries.
Victuals and vittles are also correct, but are not used in American vernacular (at least not on the east coast).
I'm a bit surprised that nourishment hasn't come up as an answer itself, although it was used in the definition of another word...
- The substances necessary for growth, health, and good condition.
The first definition would seem to include drink as well as food.
Fare - the food and drink that are regularly served or consumed
For any fans of internet culture, the answer is clearly Noms, popularized by sites like icanhazcheeseburger.com (LOLCats), wins.failblog.org and others.
I was surprised that it didn't have widespread use outside of the internet - until I picked up my kids from daycare and the carer said "they've been good today - they had all their noms"
Although "food and drink" is an accepted phrase, technically at least, there is no reason why drink should not be considered as food -- think "liquid foods". That way, I find food a sufficient word for all things that go into the alimentary canal for nutritional purposes, in whatever solid, liquid, gaseous (or plasma?) state.
I think for some living beings, their food consists exclusively of liquids. Some elderly people live on liquids alone.
So why not just say food where there is no ambiguity and food and drink where absolutely necessary?
