Due to the market

[namloan]

- These days prices of fresh food are climbing up because prices fluctuate due to the market.

- Is this sentence grammatical?

Thank you very much, Teachers

It doesn't work for me. How about something like

Fresh food prices are going up because of market fluctuations.

[freezeframe]

- These days prices of fresh food are climbing up because prices fluctuate due to the market.

Above suggestion is good.

I would add:

Your sentence feels incomplete. Market itself is a neutral idea here -- prices cannot fluctuate "due to the market" (what about the market?! your reader would ask) but because of some quality of the market.

ex.

These days prices of fresh food are climbing up because prices fluctuate due to the market instability.
