These are almost all manufactured by adding hydrogens or " partially hydrogenating" some unsaturated fat like soybean oil.

这些几乎都是通过增加氢原子或“部分氢化”了一些不饱和脂肪（如大豆油）制造的。

So trans fat and hydrogenated fats are the same thing... one refers to the process through which they are created, and the other their chemical structure.

所以反式脂肪和氢化脂肪是一回事… … 一个是指它们产生的过程，另一个是指它们的化学结构。
