How to express appositives in Japanese


I have been searching high and low for how to express appositives in Japanese,
yet the most I have come across is how to express something like "my friend
John". I would like to know how to express more complex appositives in
Japanese, something like:

> 1.) Dogs, **one of my favorite animals** , are going to be featured in
> tonight's show.  
>  2.) John, **the person you were talking to yesterday** , will be at the
> party tonight.  
>  3.) Brian McKnight, **a very popular R &B singer**, has just written a book
> about the music industry.

More specifically, I was writing a post and trying to express the following
idea:

> I had learned that Japanese people consume the greatest amounts of iodine,
> **up to 13 mg per day**!

I have expressed the first part of the sentence below, but have no clue how I
would express the appositive "up to 13mg per day" without outright creating a
new sentence.

> 日本の人が最も大量のヨウ素を食べることを知った。

I appreciate any help you can provide.




I don't think categorically ruling that "complexity" is always bad would be
wise. A lot of rather sophisticated constructions are perfectly natural to a
native speaker, and thus may be preferable over simplified options.

Now, in the case of your sentence:

> I had learned that Japanese people [...]

... I'd say that depending somewhat on the context, connecting the first
statement with the second using けれども or some of its variants (けど, けれど) would
result in a natural and not overly complex sentence, and there are many other
simple options as well (が, possibly ~て-form and more, aside those presented by
@krnk).

Depending on your feeling towards your finding (thinking of the exclamation
mark), you may want to follow that up with something like なんと to express a
sense of "surprise".
