Why All the Confusion? (aka, Is Peanut Oil Paleo?)
What is Peanut Oil?
As the name suggests, this is the oil that’s derived from peanuts. (It is also known as groundnut oil or arachis oil.)
In the US, peanut oil is commonly used in restaurants (think Chick Fil A if you’re from the South), and it’s often touted for its health benefits.
Peanut oil typically has:
— 46% Mono-unsaturated fats
— 32% Poly-unsaturated fats, and
— 17% Saturated fats
So, it’s definitely not as high in monounsaturated fats (MUFA) as an oil like olive oil (which has typically over 70% MUFA) and yet has a ton of polyunsaturated fats, which can be easily oxidized and cause the oil to go rancid.
Another key reason for why peanut oil became so popular is its high smoke point — 446F (230C). This is higher than an oil like olive oil, whose smoke point typical ranges between 338-446F (170-230C). And the more refined the peanut oil (or any oil for that matter), the higher its smoke point will be.
