whereas unsaturated fats are liquid at room temperature due to their chemical structures. “I’ve seen a lot of this conversation around dietary fat specifically, and how that impacts the heart ...

Dietary fats are saturated, unsaturated or trans fats depending on the molecular structure. Saturated fats are fats with no double bonds between carbon atoms as they are saturated with hydrogen.

I keep mentioning all these terms like unsaturated ... The process actually changes the chemical structure of the fat, turning some of it into trans fats. The oil doesn't take up all the hydrogen ...

Unsaturated fats are usually liquid and are found in plant products and fish. Chemically, saturated fats have a higher proportion of single bonds between carbon atoms rather than double bonds.
