Your desires are things you want, while motivation is your reason for performing a given action. You can be motivated by your desires ("I want to buy a new car, so I should save some money!"). Here, your desire is "a new car", and the action you take is "save some money". Your motivation for saving money is your desire to buy a new car. Technically, almost everything you do could be said to be motivated by desire ("I don't want to starve to death, so I should eat a sandwich"), but I wouldn't say they're the same thing. Just because someone wants something to happen doesn't mean their actions will reflect that.
I think you can define "fresh" best by what it's not. Fresh is:
And is generally:
- not frozen
- not dried
- not tinned
Often the sense is chilled, but not always (fresh milk is chilled, longlife milk isn't, and wouldn't be described as fresh, fresh meat is always chilled)
Of course, before refrigeration, the only way to get something fresh was to pick it just before consumption (with a few exceptions - apples, onions etc. can be stored cool and dry for some time).
You can think of the condition being (approximately) the same as in the historical case, the technology to achieve that condition not being particularly relevant.
In the sense of bakery products, "fresh" should mean baked recently- for some value of recently appropriate to the product. Generally this would mean on site or nearby, and perhaps not packed in a sealed packet.
However to describe something as "not fresh" would implies that it's past its best - slightly stale bread for example, so it's not quite the opposite.
I've tried to capture the whole range of meanings, but I'm sure I've missed some!

From my understanding, "grab some food" is close to "get some food". So it basically means acquire food, regardless of the method used. So buying it or fetching it from the kitchen would both fall under "grabbing food".
