Are the phrases correct?

Doctors advise people to cut down their salt consumption to benefit their health.

Yes it is gramatically OK.

Also possible:
Doctors advise people to benefit their health by cutting down on salt.

The construction of the first sentence is correct, and the usage acceptable. I'm sure any number of people will show up here to offer you a "superior" way to state the case, but the first sentence is acceptable as it is written.



The locution "some member" is acceptable, and one might say common--that part you did correctly. The rest of this sentence, however, limps to a lame conclusion. Your command of English is sufficiently competent, however, that i assumed that this is a writing error, which any native speaker could make, and that why you had meant to write was: " . . . kind enough to rephrase it if I'm correct." Now, if you thought the use of "what" at the end of the sentence is required, that would be incorrect.

Hi Setanta

Could some member be kind enough to rephrase it if what I'm correct? (By the way, have I used 'some member' correctly?)

Could some member be kind enough to rephrase it if I'm correct?

Yes, you're right. I've a tendency to be careless. Unfortunately, there is no medicine to cure this 'illness' of mine.

Thanks, Sullyfish and Setanta, for your replies.
