What does "take-away" mean in this context?

Question

This is a passage quoted from the article Moderate exercise not only treats, but prevents depression:

Mammen acknowledges that other factors influence a person’s likelihood of experiencing depression, including their genetic makeup. But he says that the scope of research he assessed demonstrates that regardless of individual predispositions, there’s a clear take-away for everyone. “It’s definitely worth taking note that if you’re currently active, you should sustain it. If you’re not physically active, you should initiate the habit. This review shows promising evidence that the impact of being active goes far beyond the physical.”

What does take-away mentioned in this passage mean? I've looked it up, but couldn't find a definition for it.

Answer 1

First off you have to get that this take-away is literally a noun (from the word a preceding it).

Oxford says that take-away as a noun means:

A key fact, point, or idea to be remembered, typically one emerging from a discussion or meeting.

Rephrase, the clear take-away (the key fact, the point) meant in the passage above is this:

"It's definitely worth taking note that if you're currently active, you should sustain it. If you're not physically active, you should initiate the habit. This review shows promising evidence that the impact of being active goes far beyond the physical."
