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.
