The Brain Needs Animal Fat
- mmastrac 8y agoAs a former vegetarian (now a pesco-pollo-tarian?) the important of eggs can't be understated. Arguably the one source of animal protein and fats that can be ethically sourced without harming the animal [1]. [1] vegans disagree on this point, but that's a different debate
- seba_dos1 8y agoThe problem is that while it can be, it rarely is...
- Cthulhu_ 8y agoIf the labels and laws are not to be trusted, you can always have your own chickens and look after their welfare yourself.
- harimau777 8y agoIn much of the US that's against the law (and that's not even including people who live in apartments without yards).
- rootusrootus 8y agoBut if it is important to you, then sourcing ethically produced eggs is not particularly difficult.
- greglindahl 8y agoPeople disagree about what's ethical.
- rootusrootus 8y agoTrue. I could also probably find people who think cutting down plants isn't ethical.
- wool_gather 8y agoRegardless, whatever your "ethical treatment of a fowl" criteria are, you are fairly likely to be able to find eggs that meet it.
- throwaway400 8y agoTake a drive out to the country sometime, you'll find farms that'll sell you eggs. They usually have a sign that says "fresh eggs".
- seba_dos1 8y agoHave you actually tried it? It's feasible if you occasionally eat some eggs, but if your diet is mostly based on eggs you simply won't have enough. The main reason of animal abuse on chicken farms is scaling the supply to reach the demand. Not even speaking about the fact that it's pretty difficult for somebody who lives in a city and doesn't own a car.
- hudbuddy 8y agoWorth noting that if you refuse to get fats from animals, it's important to get your DHA through algae oil.
- hudbuddy 8y agoI see now that the article mentions this
- magic_beans 8y agoI'm the same, and I happily eat farmer-raised eggs and mollusks. Mussels actively clean out water!
- Insanity 8y agoI'm a vegetarian not a vegan, and thus I eat eggs. But the 'ethically' sourced part is something I'm not that sure about. Sure they can be (and I get them from my grandparents who keep some chickens.. so that's ethical IMO). If you buy eggs from a shop, I'd say there is a fair chance that the animals are not treated that well. EDIT: I now realize many others have already made this point in other comments, oopsie.
- ravenstine 8y agoMost of what people think are "ethical" eggs that are sold in stores are basically a scam. Sure, they're eggs, but "free range" can mean the chickens have access to a little door and a puny plot of land for an hour, and "cage free" can mean the chickens never go outside. Pasture-raised eggs are your best bet, and that's all I'll buy, but even I'm skeptical because I've been burned so many times by believing my eggs were ethical.
- KozmoNau7 8y agoIt depends on local regulations, but here in Denmark, organic eggs must meet the following regulations: -Maximum of 3000 chickens in a flock and a maximum of 6 chickens per square meter in the coops, which must allow daylight in. -The chickens must have access to perches and nests. -At least one third of the flooring must be loose bedding, such as straw or sand, to allow the chickens to dust bathe. -The chickens must have all-year access to outdoor areas with at least 4 square meters per chicken. It must be covered by grass or other vegetation, and must provide shelter from wind/weather. An outdoor area must stand unused every other year, for parasite prevention and to let the vegetation regrow. -Beak trimming is prohibited. -Feed must be organic and must include roughage. While it's not perfect, it's a damn sight better than battery caged hens.
- dguo 8y agoI use this "Organic Egg Scorecard" to help determine if I should buy eggs from a particular brand: https://www.cornucopia.org/scorecard/eggs/ https://www.cornucopia.org/scorecard/eggs/
- J-dawg 8y agoUnless you're referring to the very new "no-kill" eggs [0] (which AFAIK are only on sale in Germany), all eggs involve harming an animal. And that's before we get to any concerns about how the laying females are treated. I eat eggs myself, so I'm not preaching. I just sometimes wonder whether I should.

- peteradio 8y agoI'd encourage you to find a local source. Truly an insignificant cost difference. You can see how the sausage is made and make your peace with it. The more bold could even get a couple chickens 3-4 would have a small family drowning in eggs. Maybe it's not the same everywhere but there are tons of people with chickens in the Midwest.
- J-dawg 8y agoWith respect, that doesn't really affect the point I was making. While I agree with you, the people/companies who supply those chickens to the local supplier still have no use for the male chicks. So even if you're buying eggs laid by hens that have a great life, you're still causing animals to be killed. Like I said, I have no right to be preachy. I just want more people to think clearly about this stuff. I hope the "no-kill" method becomes widespread.
- peteradio 8y agoOh I see, I did not consider roosters at all. Not really sure what you do about them. They are nice to have for protection in an open range setup. What exactly do they do with roosters in the no kill method?
- J-dawg 8y agoThey are never born/hatched - the new method allows the sex of an embryo to be determined while it's still in the egg. Effectively they are "aborted". Some roosters would obviously be preserved as breeding stock, just as they are now.
- toomanybeersies 8y agoAs a (sometimes inconsistent) vegetarian who doesn't actively eat eggs (haven't bought them in a year), I'd actually argue that eggs (and diary) are actually less ethical than meat, with (pastured) beef and lamb being the most ethical. It seems less cruel for an animal to spend its life standing in a field than for it to be stuck laying eggs its whole life or being milked twice a day for as long as its useful, only to be led to the slaughterhouse. In fact, commercial chickens are the most cruel industry, chickens are so cheap they are treated like a bulk good, rather than like a living animal. Even free range chickens live a shit life. We talk about treating our servers like cattle, rather than pets. But cattle are actually treated very well, there's a lot of value in a single beast and it's worth looking after them when they're sick. Chickens are so cheap (they cost, what, $7 at the supermarket?) that if they're sick or injured, it's cheaper just to turn them into fertiliser. Of course, that's just the commercial industry. Home raised laying hens tend to live a comfortable life.
- jrace 8y ago>(beef) and lamb being the most ethical. How is slaughtering an 8week old animal (young lamb) ethical?
- svrtknst 8y agoWell, how is slaughtering chickens ethical? For every egg-laying chicken out there, a male chicken is slaughtered, and both egg-laying and dairy milking harm the animals (for instance, compare avg. life span of a dairy cow with their natural life-span). There's also the factor of number of animals killed - One lamb feeds a lot more people than one chicken, yet both are living animals capable of pain and suffering. That's not to say that either is particularly ethical, but (as a vegan), I don't think you can easily say that eating eggs is intrinsically more ethical than eating meat.
- jrace 8y agoNot all eggs come from industrial slaughter farms. At least where I live farm fresh eggs from chickens who live cage free are readily available. But the point of my comment us not that Lambs are less ethical than chickens...but killing and eating a few week old animal is hardly "more" ethical.
- benj111 8y ago"but that's a different debate" Is it? Seems quite central to the debate to me.

- rhacker 8y agoNice chart didn't know existed ;) I actually was a Fruitarian once - basically just ate mangoes, oranges, apples, etc.. all day long for a month. It was incredible. Dad from India so a lot of vegetarianism in my blood I suppose. My wife on the other hand couldn't make it last too long. I wholeheartedly recommend fruitarianism if you can make it work (might not be easy).
- chongli 8y agoArguably the one source of animal protein and fats that can be ethically sourced without harming the animal [1]. I think dairy also applies. Yes, lots of dairy operations in business today are cruel. But they don't have to be. There are dairy operations now that let the cattle decide when to be milked. The machines are fully automatic. The cattle need not be separated from their calves, either. With all of those systems in place, there is no real ethical difference between the dairy operation and a human mother using a breast pump and donating the excess to a milk bank.
- maxerickson 8y agoIsn't there a deep ethical difference when the human has autonomy and the animal doesn't? I don't think it's immoral to keep livestock, I'm questioning whether the situations are analogous in an ethical sense.
- chongli 8y agoYou're providing the animal with a space to live, safety from predators, safe food and clean water, and the freedom to roam a potentially large landscape. Yeah, the animal is not autonomous. Do animals understand autonomy? Can they tell the difference? Maybe whales in capyivity can, but they are used to roaming the vast oceans. I think cattle would be perfectly happy in such an environment. Anthropomorphizing them is not helpful.
- maxerickson 8y agoI'm not anthropomorphizing the animal, I'm drawing a distinction between the ethical considerations when autonomy is a factor and when autonomy is not a factor. You compared them earlier, I questioned the value of that comparison (a human can give their milk; it is taken from the animal). None of that is an argument that it is necessarily unethical or immoral to take milk from an animal. Repeating the point: to me, the ethics of collecting milk from autonomous creatures that willingly give it are a separate thing from the ethics of taking milk from creatures that do not have autonomy.
- rygxqpbsngav 8y agoThere are lot of cultures all over the world who never even smell animal food and has the best brain power. This article is a load of BS. This kind of mediocre baseless studies ignoring centuries of human history have done and are doing immense damage to humanity these days than any other single most source. > If you choose a plant-based diet, supplement properly Oh yeah! How did humanity survived and lived centuries without this stupid knowledge and these super awesome supplements developed just now?
- AllegedAlec 8y ago> There are lot of cultures all over the world who never even smell animal food and has the best brain power. Such as?
- rygxqpbsngav 8y agoBrahmins in India. Strictly, never touch animal food. Go to any veda schools in India, they can recite whole Vedas on their tongue, modern fools eating animals will never even able to pronounce it properly.
- fs111 8y agoYou claimed there were "a lot of cultures". Can you name any more?
- rygxqpbsngav 8y agoPeople who practice Jainism, never touch meat in their whole life. They even avoid certain foods like Onions, Garlic etc. There are more. Why are you asking? Meat is not required as food. Period.

- cageface 8y agoThis is nonsense. As the article itself states, if you're really paranoid about this then just take an algae supplement, which contains plenty of DHA. That's where fish get it. They don't make it themselves. And it doesn't come with all the pollutants you get from fish these days either. The amount of these fatty acids needed by the brain is quite small and even at low conversion rates can easily be met by conversion from other plant sources too. Summary of research on the subject: https://www.youtube.com/watch?v=XMA5ij-bsKc https://www.youtube.com/watch?v=XMA5ij-bsKc
- eggie 8y ago> ... if you're really paranoid about this then just take an algae supplement, which contains plenty of DHA. That's where fish get it. They don't make it themselves. And it doesn't come with all the pollutants you get from fish these days either. The article does note that the bioavailability of this for humans may be very low. We are not fish. We did not evolve to eat algae. If you'd like to be as healthy as you can be, eat meat, sometimes, and don't ignore your body's cravings for fat.
- cageface 8y agoThe linked video addresses this. Supplements work in this case. Eating meat and fish has a lot of downsides too. For your health, for animal welfare, and the environment.
- rootusrootus 8y agoIf the statistics in the article are correct, supplements might work but are not being utilized.
- dalore 8y agoEating meat isn't unhealthy. The studies quoted often are correlation studies where they don't take into account people who eat red meat probably don't do a lot of things they are told to do and so statistically die more, but it's not from red meat. Animal welfare is a big one, and only by highlighting the problem and use sustainable farming practices will it work. Note that large scale vegetable farming practices are also bad for the environment, due to mono culture, soil degradation etc. So the best way is to farm both in a symbiotic relationship.

- IWeldMelons 8y agoI am a vegetarian, and consume very little animal fat. My brains works just fine. Generally this article goes against massive amount of evidence that vegetable fats just healthier than animal fats.
- virtuexru 8y ago> My brains works just fine. I'm sure this wasn't meant to be funny but it gave me a good laugh and brightened up my morning so thank you! :)
- rootusrootus 8y agoI'm glad I wasn't the only one to chuckle when I read that. Kind of a guilty laugh, admittedly.
- IWeldMelons 8y agoYou are very welcome. I am not sure what exactly was funny, but I, and much of the other commenters here, are not native speaker of English, and, as the result, occasionally make linguistical blunders.
- rossdavidh 8y agoI think "vegetable fats" is too broad a term here. I have been a vegetarian for 32 years, and my brain also works just fine, but there are certainly some vegetable sources that are not great for you. The vegetable oils that get used in lots of processed foods, that are not part of any traditional diet, are especially suspect.
- lelima 8y ago"My brains works just fine" What if the article is true and you are only using, let's say 80% of your capacity. It will be fun if you try to make some Sudoku or something similar and test the time, then eat those animal meat and try it out. eg: When I drink coffee I become at least 20% better solving problems

- maxxxxx 8y agoThere are plenty of life long vegetarians in India so this article seems nonsense. I would agree that people should watch their diet and make adjustments but categorically declaring that we need animal fat doesn’t make sense.
- Angostura 8y agoFrom my travels it seemed that most Indian vegetarians were happy to drink milk, and quite a few ate eggs.
- maxxxxx 8y agoThere are also plenty who won’t touch any kind of animal products. You certainly have to adjust your diet but you don’t “need” animal products.
- rootusrootus 8y agoIt's been proven that you can survive eating nothing but hotdogs. But ... it probably wouldn't be advisable in general.

- kantord 8y ago> The Brain Needs Animal Fat > Thankfully, vegetarian and vegan-friendly DHA supplements [..] are available. Both from the same article
- ensignro2340 8y agolmao that’s was my reaction. I’ve been taking DHA supplements and eating a plant-based diet for over a decade. I thought the article might expose some skeezy marketing ploys on the part of BigVitamin, that I had been buying into all along, but alas.
- sneakernets 8y agoAny anthropologist or scientist worth their salt knew this for years. Cooking meat is one of the main reasons fire was controlled, and anyone who didn't eat meat was usually for religious reasons or during a famine. I'm just as appalled as anyone else when it comes to the ethical treatment of animals, but to deny that we didn't evolve to be omnivores despite overwhelming evidence is... well it's silly.
- ben_w 8y agoThat’s not a very effective argument for doing it now. Whatever drove our ancestral evolution is no longer a major part of our environment. We selectively bred plants and animals, wiped out various diseases and created environmental pressure for others to change, and the development of preservatives and refrigeration and cheap long-distance travel means we can combine foods which our ancestors could never find in the same place at the same time. Plus the whole 33 year life expectancy at birth/54 year life expectancy if you reached 15 in the Paleolithic.
- tnzn 8y agoAnthropologists are careful to call for ethical decisions based on evolutionnary arguments.
- nickelcitymario 8y agoThe article is okay. The headline is clickbait nonsense. The headline implies that vegans should all be dead now, assuming we interpret "need" as necessary to survival. A more accurate title might be "The Brain Benefits From Animal Fat". But who would click that, right?
- ravenstine 8y ago[deleted]
- zwaps 8y agoRe-read the article. ALA->DHA reformation has an efficiency of less than 10%. The point that is made here is that you certainly have to ingest a lot of ALA rich food to make that work, and it is not recommended for children at all because of brain development. Furthermore, DHA levels ARE lower in vegans and vegetarians. So either you claim the human body actually does not need DHA, or you you claim that the body can do ALA->DHA. In the latter case, the article talks about it.
- alexmingoia 8y agoDHA levels in blood being lower doesn’t mean much if they get enough DHA. Higher blood levels may mean those people consume more than is needed. AFAIK there is no clinical DHA deficiency established by the literature. Consider that diets that include fish don’t get anywhere near 1.5g a day of DHA, and that many humans didn’t eat fish at all. Fish oil supplements are a relatively recent phenomenon that came about without any evidence of deficiency. I don’t consume any dietary DHA or EPA and don’t supplement. I’m fine, as is every person like me (vegan or not).
- CharlesColeman 8y ago> This article isn't correct. The human body synthesizes DHA from short-chain omega-3 alpha-linolenic acid (ALA), which can be found in things like hemp, flax, algae, pumpkin seeds, etc. That's true, but is that pathway effective enough to effectively provide what the body needs for optimal function? IIRC, the ALA -> DHA pathway is quite rate limited. > I have a hard time believing anything said about the need for certain kinds of nutrients. I've done all-cheese diets, all-meat diets, and all-plant diets for months on end with no serious side effects other than constipation and boredom of eating a monodiet. The human body is resilient and doesn't need to be fed as much as people think. I don't think a few anecdotal short-term experiments with extreme diets say much about what the human body needs to function well. The human body can be somewhat resilient in the face of malnourishment, but it doesn't follow from that malnourishment is an acceptable state. It's sort of like this: If you've got a four-server cluster for your application, would you rather it be in a state where two offline due to hardware failures, or would you rather they all be functioning normally? The former might be an example of "resilience," but your users might also be experiencing slowness issues due to the reduced capacity.
- floatingatoll 8y agoARA has been found to be produced by a lichen, iirc, and so is now available as a vegetarian supplement. (It may or not be vegan, depending on whether you consider lichen animals.) EDIT: I remember imprecisely.

- andosteinmetz 8y agoThis article appears to have a clear agenda and does a poor job of hiding it. The conclusions, which might be summarized "animal fats are good and plant fats are bad" also seem pretty feebly supported by the evidence offered. I am not a scientist, but to my eye this shows the marks of industry supported junks science.
- deleted 8y ago[deleted]
- purplezooey 8y agoThe article mentions coconut oil which seems to be a big mystery. Some people say it's long chain saturated fat which is bad, but others say it's actually medium chain and good for you.
- alexmingoia 8y agoThis is nonsense. I’ve been a vegan for years and do not supplement DHA or EPA. My body converts everything from ALA. My blood levels are great. There is no such thing as clinical DHA defiency established in the literature. What regulates ALA metabolism is poorly understood, but it seems when you don’t get DHA and EPA your body does fine, as evidenced by every vegan alive. Also there isn’t much DHA or EPA in a diet that includes fish. You can’t get the 1.5g a day that’s recommended by eating fish or eggs in your diet. Yet humans were doing just fine before fish oil supplements.
- cdumler 8y ago> It is difficult to be sure precisely how much DHA we need, as DHA conversion rates and availability can vary significantly depending on age, gender, genetics, and dietary composition Vegetarianism/veganism has the same problems with calcium and B12, as those are typically gotten through animals in omnivore diets. It doesn't mean that vegetarianism/veganism is bad, just that you have to be conscious of your diet. We have a phrase in our house: "You need to eat all the colors." We include a wide variety of foods in our diet, and milk replacement products with calcium. As a critical thinker, it bothers me when something says "Well, we don't understand what this relationship is or its importance; therefore, you should conclude.." Seems like a hit piece on vegetarianism/veganism more than anything else. Nevertheless, recognizing the importance of certain fats in your body is a good thing.
- alexmingoia 8y agoThere are plenty of sources of calcium in vegetables, it’s not comparable to B12 (which has been found to be produced in the human upper intestinal tract as evidenced by multiple studies going as far back as 1980 https://www.ncbi.nlm.nih.gov/m/pubmed/7354869/ https://www.ncbi.nlm.nih.gov/m/pubmed/7354869/, despite the claims all over the Internet otherwise. It’s just poorly understood why some guts lack it). The only thing a vegan has to supplement with a proper diet is B12. Eating tofu and fortified soy milk every day gets you most of the way there for calcium (it’s set using calcium sulfate as coagulant). I’ve already had 300mg in my breakfast today by eating oats with fortified soy milk.
- DonnyV 8y agoI love pork chops, steak, lamb and eggs. Nothing wrong eating any meat products. Now I do have issue on how they are raised because I believe it affects the quality of the meat. But you have to be honest with yourselves. These animals have been modified for human consumption. They are not what nature intended them to be. Cows are almost completely different to what they were originally. Chickens are like 3 times bigger than what they used to be. These animals have been made to be eaten.
- HillaryBriss 8y agoi'm not sure which side has the better balance of evidence, but, FWIW, one argument i've seen on the other side of this discussion is: DHA/EPA are highly polyunsaturated and, at human body temperatures, oxidize more easily than they do at cold water fish body temperatures. so, by consuming pre-formed DHA/EPA on a regular basis, the argument goes, a human body must bear the burden of dealing with a fat that oxidizes readily and damages other bodily cells.

- cannonedhamster 8y agoThis article is written by a crusader for meat with a clear agenda of being vehemently pro-meat. She supports the keto-diet, which has no real basis in history or science, the person she cites actively disagrees with her dietary suggestions. She cites inflammation and healing as side effects, but doesn't describe what gets inflamed, where it gets inflamed, or how. She also makes a claim that vegans and vegetarianism will lead to mental disorder because of this lower DHA claim. Well where's the data that vegans/vegetarians have higher instances of this? Should be easy to produce right? She even makes the claim that vegetables have no science to prove that they are healthy. How did this even get onto HN, it's obviously garbage?

- _i____ii_______ 8y agoAt this point in my observation of the diet wars I have concluded that no diet is based in science and everyone is wrong. Like religion.
- cannonedhamster 8y agoI think this is a pretty fair assessment as human nutrition needs can vary wildly based on a variety of factors. Some people obviously have nutritional deficiencies that are best addressed by eating meat. Most people need to eat more veggies. I think the omnivore's dilemma comes closest to a solid diet for humans.
- cageface 8y agoIn fact we have a lot of very solid science on nutrition. It's just that some companies with billions of dollars to lose are doing their best to confuse the issue and get everyone to give up, just as you have. It's straight out of big tobacco's playbook.
- sridca 8y agoYup. Have you also observed that the HN community has a vegan/vegetarian-bias? People here jump to prompt criticism and ad hominem when there is a pro-meat submission. And right now that Burger King vegan burger loaded with questionable ingredients is being lauded as the greatest achievement in nutrition.
- mbostleman 8y agoIt's too bad that the reactions to this article are so quickly approached as if it's a wholesale indictment of plant-based diets. Maybe it doesn't mean that veganism should be immediately stopped worldwide. Maybe it means there's opportunities to optimize what is already a mostly good thing. The fact that an individual poster is vegan and, in his opinion, "is fine" is obviously not useful. The fact that hundreds of millions of people in India are to some extent mostly plant based and are are "Ok" is not useful because a) they are not necessarily 100% plant based and b) what is the definition of "Ok"? They continue to live obviously but who's to say they can't be better? There are plenty of negative characteristics of Indian health - as there are for any population - that could be correlated. If there is a causal link found, maybe it would prolong life and/or life quality. The assertion that the writer is funded by big meat is not useful. If someone says the sky is blue, the first thing to do is look at the sky to see if it's blue - not question whether or not the speaker is paid by the pro-blue sky lobby. It's unfortunate to see cultural movements smother science. I'm not saying that this article is science or is even correct science. But until a rational discussion is allowed that even allows such an evaluation we can't know.
- andosteinmetz 8y agoI think the main problem with the article is that its modest scientific content about the benefits of DHA is buried in a pile of overblown conclusions, assertions that consuming meat products is essential to good mental health, and innuendo that vegetable oils are unhealthy, none of which claims are adequately supported here. Questions that might clarify the facts surrounding these claims are left conspicuously unanswered and unasked. Likely because the purpose of the article is not to to present the available evidence and carefully draw conclusions, but to support a diet based on animal fats by cherry picking from the science where convenient.
