  • Defatting nuts?

    This is a bit of a strange question but does anyone know of any methods for extracting the fat from nuts, in such a way that the nut is not destroyed? Shea butter, for example, is made by roasting the seed till its completely burnt, and then crushing it, etc etc... but is there any way to get the oils out without losing the nut?

      Most oil extraction processes from seeds/grain are either mechanical pressing, or chemical extraction, which uses a lot of nasty chemicals. It's okay for getting oil out of algae, or rapeseed, 'cause...well... who would eat that? .... oh, wait...

      Anyways, no, not that I'm aware of, unless you are willing to use a lot of nasty chemicals.

        Again, it's a little weird... I love nuts but am looking to get around the pufa issue by extracting the fat.

          Yea thats a tough one. There is no way to actually de-fat a nut without destroying the nut but you could look into sprouting and roasting to see if they have any effects on the PUFA content. Also eating along side some coconut might displace the pufa, making sure you get vitamin E could also help. There might even be other things you could eat along side the nuts that could off set the pufa content but i am not sure.

            Um, I don't think that's going to work. Pufa stands for poly unsaturated fatty acid. The fat has all the pufa. The rest is mostly fiber and a bit of carbs. Nothing worth eating.

              I don't really eat nuts, except here and there as an ingredient in recipes. I could take them or leave them. I used to really, really love bread though. I haven't replaced it with faux bread, or some kind of sprouted, fermented, magic sour dough. I mostly just gave it up. I have some of the real thing, now and then, less and less as time goes by.

              I think if you really believe a particular food is not in the best interests of your health, it's best just to give it up. That's my (long term) plan for beer.

                Powdered peanut butter,PB 2, is defatted nut product you could buy though it is peanut butter so it's not entirely primal...tastes great though, low calorie snack and cures my peanut cravings!
                Mix it in almond milk and BOOM BOOM BOOM dessert

                  Funnily enough, I used to be a fiend for pb2 before going primal/paleo. I wonder if the defatting process removes some of the worrisome traits associated with peanuts... thanks for the suggestion!

                    By warming and grinding nuts, then pressing them, you could extract the oil, leaving a hard paste that contains protein and fiber and could be used as a flour. Sounds equipment-intensive.

                      Well I spent longer than I should have googling this, and as that is the case I figure I may as well share my findings, though I think this probably is not a worthwhile enterprise.

                      Lots of people online say that almond flour (as opposed to almond meal) is usually partially defatted, but calorie counts suggest otherwise.

                      De-Fat The Nuts, Freezer Burn "Fix", Re-Use Those Dryer Sheets, Free Stud Finder For Remodelers and MORE! is one thing you could try. I have no idea how much fat would actually leech out of a chopped nut when you roast it.

                      And finally, this was just bizarre, I read a US patent from 1990 (just google "how to defat nuts" -- it was the first result). Apparently this is like a common problem for crazy food scientists, and there must not be a good way to do this (besides as a by-product of making nut oil) otherwise we'd all be able to buy low fat roasted nuts in a jar at the grocery store.

                      Oh another idea: you could buy a "natural" nut butter and then waste the oil on top.

                      But like I said, don't pay attention to any of these things. I just didn't want to feel like I completely wasted half an hour.

                        I had read an actual study, pointing out the fact that only about half of the fats in nuts is actually absorbed and metabolized by our bodies.

                        My personal experience from eating plenty of nuts and their butters has kinda proven that also. Just don't ask me how I knew, cause the answer is kinda in the tmi category.

                        I'd say don't worry about it. PUFAS or what not, if it's natural, whole food.....

                          and how many nuts are you eating?
                          As I ate the oysters with their strong taste of the sea and their faint metallic taste that the cold white wine washed away, leaving only the sea taste and the succulent texture, and as I drank their cold liquid from each shell and washed it down with the crisp taste of the wine, I lost the empty feeling and began to be happy and to make plans.

                            interesting stuff... your time wasn't wasted, I actually read all of it and found it interesting!

                            noodletoy -- for the past few months I've been eating no nuts whatsoever (I had one glass of almondmilk back in February but considering how many almonds go into a single cup, it's really negligible). I miss them though, which is why I'm interested in this topic.

                            Honestly, I might just go with PB2. The big issues with peanuts seem to be eliminated through the grinding process and the fat removal process.

I love it and I would jump for joy if it turned out to be less harmful than regular peanuts or peanut butter! I mean, the only ingredients are peanuts, sugar, and salt (and cocoa powder, with the chocolate one.) I mean, the verdict would probably come to be "not primal" but maybe he'd say it's okay for a once in a while type of thing.

                              I can always dream... lol.
                              Here's my logic: Mark says there's a few main problems with peanuts.
                              1. aflotoxins, a bacteria from the ground which appears in many crops. However, the process used to make peanut butter reduces aflotoxins by around 89%.
                              2. agglutinin, a lectin which in some in vitro (not in vivo) studies showed a correlation with colon cancer cells. These studies don't show much about what happens when peanuts are ingested, however -- and there are some studies which show that frequent intake of peanuts and peanut products was linked to a lowered incidence of colorectal cancer in Taiwanese women
                              3. the oils, apart from being largely pufa, might be atherogenic... however, not only is this merely speculative, but pb2 is ground peanuts with the oils removed -- which renders this a non-issue.

                              Unless anyone can think of something I'm missing, I'll probably go for it. As they say, "nobody gets out alive" -- and as a healthy 21 year-old, my main reason for being primal is effortless weight maintenance. Pb2 seems like it could be a pretty handy tool in my pantry.
