I hear Peat talking about complete hydrogenation of coconut oil, which removes all unsaturated fats, both cis and trans forms.
It wasn't until he was able to find a supplier who could do complete hydrogenation of coconut oil that he switched.
As usual, he gives us lots to think about. Can we find a supplier of completely hydrogenated oil? Should we try to do complete hydrogenation of oil ourselves, the theory of which is explained in this video (but not the actual how-to)?
