Why is palm oil so common in gluten snacks?

I have been glutenfree for 6+ years, and one thing that perplexes me is the amount of palm oil in gluten free snacks.

I find it strange that companies that create snacks for people needing a sustainable diet, don’t also think about sustainable for the planet.

What are your thoughts?

For context i live in the UK.
