I think "Exercise and healthy food are important for keeping our bodies healthy" sounds better.
Agree. We don't share one body!
Shouldn't keep be tetap? Agar is more like so that. As in " so that are body is healthy" another would be for as in " for a healthy body"
Again, this mysterious use of "itu".
Where is the "keep" ???
Once again, sloppy grammar from Duolingo. It is NOT 'our' body, it is our bodies. Also, i agree with IlseDens, where is the keep?
Why not "Exercise and healthy food are important for our body health"?
