I made this sentence: there is a concern that unrest such as the political crisis due to insufficient food supply in 2007 might recur.

Althogh it was me who made this sentence, on re-reading, this felt somewhat worng.

It's mainly in relation with the use of "due to."

I tried to figure out what is wrong only to fail.

At first glance, I thought due to cannot be used this way.

Then I thoght this is a sentence in which subject and verb are omitted like the political crisis (which was) due to insufficient food supply...

So, to me, this sentence seems gramatically correct, but feels weird.

Is this just because I'm not familiar with this kind of sentence or is this sentence actually wrong?
You could say that, but I wouldn't hold out hope for its truth over the long run!
This is OK:

There is a concern that unrest such as the 2007 political crisis due to insufficient food supply might recur.

"Due to has been widely used for many years as a compound preposition like owing to, but some critics have insisted that due should be used only as an adjective. According to this view, it is incorrect to say The concert was canceled due to the rain but acceptable to say The cancellation of the concert was due to the rain, where due continues to function as an adjective modifying cancellation. This seems a fine point, however, and since due to is widely used and understood, there seems little reason to avoid using it as a preposition.

"Due to" meaning "caused by" is undisputedly correct in contexts where "due" can be construed as an adjective (e.g., "failure due to carelessness"). Its use in contexts where "due" is an adverb

("He failed due to carelessness") has been disputed. Fowler says that "due to is often used by the illiterate as though it had passed, like owing to, into a mere compound preposition". But Fowler was writing in 1926; what hadn't happened then may well have happened by now."

I don't have any more expressions to extend my gratitude to you.

You never diappoint me.

(can I say, "You never fail me"?)

Thanks a lot.

Your problem here is that you've got three prepositional phrases between your subject and your verb.

In English we like the verb to come right after the subject.

The first time I read this sentence I thought (the) insufficient food supply was the subject of might recur.

I had to read this sentence twice to find the subject of might recur.

You can make this sentence clearer by saying the political crisis resulting from the insufficient food supply

I had another problem understanding the sentence. When you say unrest, such as a political crisis, you are saying that a political crisis is like unrest. It isn't. Unrest is students demonstrating in the streets. A political crisis is a military coup, or at the very least, a change in the ruling party.
