This is a continuation of an off-topic discussion in the lovely Optimal Micronutrient Ratios discussion thread.
Macadamia nut oil is interesting because it has a unique fat makeup of roughly 81% monounsaturated, 3% polyunsaturated in a 2 Ω6 to 1 Ω3 ratio, and 16% saturated fats. It has a smooth buttery slightly nutty flavor. (I’ll let you know for sure after I taste it.) It is very shelf stable partly due to its low amounts of polyunsaturated fats. The price is probably the worst part. It is the most expensive nut to purchase in the world, isn’t it? Another bad part is that some people are allergic to tree nuts. Just on the price and allergenic point, I think it’s safe to say this will never be a part of official Soylent.
So why is it an interesting oil? Its fatty acid makeup. (And hopefully flavor too!) It generally has a very high Oleic acid content, like olive oil. I write “generally,” because these things apparently change a lot depending on “the cultivar, maturity of the fruit, altitude, climate, and several other factors.” It seems like a good fatty acid to get a majority of your calories from. There’s an ongoing discussion about ideal ratios, ideal amounts, and safe amounts of lots of nutrients, including different fatty acids, going on in the thread I linked to at the beginning.
It is also low in polyunsaturated fats, and in particular, Omega-6 (Ω6). If you are looking to minimize your Ω6 intake to some level of your choosing, while minimizing saturated fats, this seems like the ideal oil.
For a more complete breakdown of the fats, here is one supplier’s information: Textron Organic Macadamia Oil Product Data Sheet.
Although the oil is perfectly fine to eat, (but possibly some produced aren’t food grade, make sure and check!) this producer is currently targeting towards cosmetics and doesn’t have complete nutritional information available on that data sheet. For example, the oil should contain, at the minimum, some amount of vitamin E. Any help finding a complete profile for the oil in general and posting it here would be awesome!
Interestingly, the NOW Foods brand oil has a makeup that shows some of the ranges from Textron’s data sheet averaged. I think there’s a good possibility that Textron is their supplier.
If we can’t find real nutritional data, I’m planning to look to see if there’s a significant pattern in what micronutrients are in a given nut compared to its oil. If there is a significant pattern, I plan to use that to estimate what’s in macadamia oil compared to the USDA nutrient database profile of a raw macadamia nut. Maybe just eating raw macadamia nuts to begin with would be best… (I have tasted one raw, guerilla style, from a road in Hawaii. It is very different from the roasted taste, FYI. I liked it, but I don’t think most do.)
You probably shouldn’t only consume this oil. At this point I’m looking into using it along with olive, krill, and maybe a little coconut oil. I’m researching a daily fat mix that would put my Ω3 intake at 1.6g to 3g, my intake of Ω6 at roughly 2.3x that while keeping Ω6 below 4% of overall daily kcal, minimize but not eliminate saturated fats, keep Euric acid under 500mg, minimize Palmitic acid and get 40% of the kilocalories from my diet from fat in general. I’m still researching, but the end goal is 40% kcal from fat, 20% kcal protein, and 40% kcal carbohydrates. Sound vaguely familiar? It kind of lines up naturally, more or less, to what I’m trying to put in my nutritional ooze… my Nutriooze™. I’ll put my recipe up, whenever it gets finished, in another thread for you all to laugh at and tear apart.
But to the topic, what do you think of macadamia nut oil, my new fall fling? Has anyone seen good, reliable information about it in general, and in particular its full nutritional information? Are macadamia nuts dry roasted before they are pressed into oil or do they press them raw? If you really care about avoiding pesticide doses over safe limits, do you have to buy an organically farmed nut oil? I have found opinions either way, but not any empirical evidence yet.
