Macadamia nut oil is technically a seed oil (something we generally advise against), but this one is different. Unlike most seed and nut oils, which are made up of mostly polyunsaturated fats (PUFA), macadamia nut oil consists of largely monounsaturated fats, followed by saturated fats and only a small amount of PUFAs.
Paleo and PUFAs
Most of us living a Paleo lifestyle try to avoid the PUFAs because they are much less stable and more likely to oxidize than saturated and monounsaturated fats. Consuming oxidized fats is dangerous because it creates oxidized cholesterol in our blood – the stuff that tends to latch onto the insides of our arteries, causing inflammation and plaque build-up.
A Very Stable Fat
Macadamia nut oil has also literally withstood the test of time, proving itself to be one of the most shelf stable oils out there. This means you can hang on to your bottle of macadamia nut oil for months without having to worry about it going bad, so long as you store it in a cool, dry place, away from direct light.
