Trans fats

[koster]

Are trans fats and hydrogenated fats the same thing?

Thanks!

No.

All naturally occuring unsaturated oils are 'cis' (the opposite of trans).

When oils are hydrogenated (for example, to make margarine) they become saturated and are neither cis or trans.

However, some research has shown that re-use of cis oils in deep frying can produce trans fats.

Thank you.
