Can unsaturated fats become saturated?

[leopard]

I know that unsaturated fats are healthier than saturated fats. It's therefore supposed to be better to use f. ex. olive oil than butter in food. When I fried some fish in olive oil yesterday, I thought: maybe the heat can cause the unsaturated fats to become saturated by breaking the double bonds? Is this possible?

 

[Borek]

Just breaking the bonds doesn't change unsaturated chain into saturated chain.

And add some hydrogen from the air.

And add some hydrogen from the air.

Have you seen hydrogen in the air?

 

[leopard]

No. Add some H from the fish then.

 

[Borek]

Like in leaving just fis?

 

[leopard]

Yes.
