Looks like only available in one restaurant for now, but it's a start.

"For one thing, cultivated meat is not vegan or vegetarian." -> I know some vegans who would disagree with that, on the grounds that no animal cruelty or slaughter is involved. I suspect there will be a fair bit of debate on this as cultivated meat becomes more widespread. I would guess just like we've already got "I'm a vegetarian who eats fish" we'll end up with "I'm a vegan who does/doesn't eat cultivated meat."

You might want to cross-post this to !food too.

I know some vegans who would disagree with that

I definitely would!

Usually, the reason people go vegan is to try to reduce (hopefully eliminate) animal suffering, and/or to reduce green house gas emissions from animal farming.

Cultivated meat deals with the first, and, depending on how it's produced, can probably entirely avoid the second as well.

I don't know the process in detail, but I would also imagine that cultivated meat is no more sourced from animals than a plant that was fertilized with animal dung, and that would still be considered vegan.

There are some analyses out there that suggest cultivated meat will actually be worse for the climate than animals - for example https://www.ucdavis.edu/food/news/lab-grown-meat-carbon-footprint-worse-beef

Of course the cultivated meat startups disagree: https://www.npr.org/2022/11/21/1138371310/a-taste-of-lab-grown-meat

[–] Dee_Imaginarium@beehaw.org 18 points 1 year ago* (last edited 1 year ago) (2 children)

I was going to say, all the articles and science I saw on lab meat previously had it consuming far, far less resources than the traditional beef industry. Definitely going to read more about it but I'm still team lab meat for now.

Edit:

"But in a preprint, not yet peer-reviewed, researchers at the University of California..." That's not a good start to their point.

The comments on that preprint by another expert also don't seem promising on their conclusions of lab grown.

I'll believe it's worse than traditional beef when more science substantiates that view. This article isn't that.

[–] TechyDad@beehaw.org 16 points 1 year ago

Even if cultivated meat was initially bad for the environment, I'd guess that it would be easy to minimize it's environmental impact versus traditional meat. There's only so much you can do to stop cows from belching CO2. However, a factory making vats of cultured meat could install pollution controls to reduce their emissions.

I'd definitely like to see peer reviewed studies backing everything up, but my guess is that cultivated meat will on par with or be better for the environment than traditional meat and will only get better.

[–] ffmike@beehaw.org 9 points 1 year ago

Yeah so far it seems to be battling experts. UC Davis is a big agriculture/animal science school. On the other hand I don't trust the lab meat industry's own experts either. Hoping at some point to see a credible neutral analysis.

[–] NecoArcKbinAccount@kbin.social 10 points 1 year ago

I've read it, and there's already two issues:

  • Not peer reviewed, so more margin of error
  • It says that it will only be worse if the stuff needed to make lab grown meat is purified at pharmaceutical levels; if the stuff is food grade then the claim begins falls apart.
[–] Woovie@kbin.social 8 points 1 year ago

I think it's odd to even compare. One is a brand new industry, the other is a hundreds of year old process in terms of learning how to make it efficient. Over time, I have no doubt lab-grown can out-carbon footprint actual cattle raising.

[–] The_Terrible_Humbaba@beehaw.org 4 points 1 year ago (1 children)

That was an interesting read, thanks for the link!

But yeah, I had no idea it was so much worse for the environment. But it seems there's still the possibility it will be better one day, so I hope for the best. I guess in the meantime I'll stick with plant-based foods.

[–] abir_vandergriff@beehaw.org 2 points 1 year ago (1 children)

You should check out issues brought up about this article by other comments since yours.

Oh, I did see some of them later, but thank you for the heads-up!

I noticed it wasn't peer-reviewed, but when they mentioned the process and I started to imagine all it must take to cultivate meat in a lab, it started to seem that it could be a lot worse for the environment than I had really considered, and it didn't seem implausible that it could be worse than farmed meat.

Either way, at this point I would be willing to bet it definitely isn't as sustainable as just eating plant based food, so I'd rather stick with that for now; I'm accustomed to it already anyway.

They biopsy live animals to get the cells to grow meat, so I am sure many vegans will object -- but the labs theoretically never need to get more cells. The question becomes whether they do or not and how the source livestock is treated. Do they just sell the source animals to a slaughterhouse? Or do they donate them to a petting zoo? They are unlikely to tell the public.

I noticed the post's link is PR from the Upside company website. GOOD Meat is another provider. Here is an NPR link with a bit less sensationalism: https://www.npr.org/sections/health-shots/2023/06/21/1183484892/no-kill-meat-grown-from-animal-cells-is-now-approved-for-sale-in-the-u-s

I know they biopsy animals to get the cells, but I just assume it's a one and done thing since there's no need to go back; or at least just once for each company working on it. If it's more than that, it would completely defeat the purpose and probably not be worth it for them.

Not perfect, but assuming they only do it the one time with an animal that was already likely to be slaughtered, I think I'd still consider it vegan.

Either way, I'll probably still stick more plant based. Even if lab meat is better for the environment than farm meat, it still needs to be "fed" and so will probably always take more resources than plant based to be produced.

[–] TechyDad@beehaw.org 7 points 1 year ago (1 children)

I'm not vegan, but I do keep Kosher and I'm sure there would be a huge debate in the Jewish community as to whether cultured meat was kosher.

Assuming that the animal that the original cells were taken from was Kosher (e.g. a chicken or a cow, not a pig), then would the cultured meat be Kosher? Would it not need to follow usual processes (specific slaughter techniques, salting and soaking the meat to remove blood, etc) if there was no animal/blood?

As cultured meat takes hold, there are going to be a lot of communities trying to take it into account. I'm sure there will be plenty of arguments as to the status of it as well. It should be interesting.

[–] FatCrab@lemmy.one 6 points 1 year ago

This is a fascinating issue, though it looks like from that article that there is no consensus. I think I'd side on it being kosher and pareve though as Rabbi Lau asserts in that article. The root principle of kosher laws is food safety and kindness to animals (however misguided that is given the we now know schechting an animal is actually horrifically cruel to it). Moreover, the rule against mixing meat and dairy derives from the prohibition on boiling a calf in its mother's milk. Cultivated meat is the least cruel method of acquiring meat obviously and it has no mother, so kosher and pareve in my book.

[–] GeenVliegtuig@kbin.social 3 points 1 year ago (2 children)

I know at least one person that has preemptively rejected cultivated meat because it requires the death of an animal.

Even though they know that a single animal's death could then spare uncountable billions of future animals.

... does that make the chicken sampled for cultivation Chicken Jesus?

[–] Ertebolle@kbin.social 6 points 1 year ago (1 children)

If you're going to start rejecting things because even one animal died in the process of making them, you'd have to say goodbye to much of modern medicine too.

[–] HipHoboHarold@kbin.social 4 points 1 year ago (1 children)

I would argue at some point they would need to reject modern living as a whole. Go build an A frame in the woods. Forage for berries and shit. Many aspects of the ways we live cause deaths. Like cars hitting animals. So if a single animal is too much, I have a feeling they should really be following that mindset.

[–] chatterbox@kbin.social 2 points 1 year ago

The amount of animals killed by a modern farm tractor combine passing through is enormous. Its just that we don't count "vermin" like that life. And most people who are vegan will never see it.

[–] leetnewb@beehaw.org 1 points 1 year ago

I don't think that cultivated meat technically requires the death of an animal at all.

[–] borkcorkedforks@kbin.social 2 points 1 year ago (2 children)

If the vegan is there for ethics then cultivated meat should be all good. More ethical than cheese or leather anyway.

Maybe some will complain about the source of the starter cells or something.

[–] JoGooD@kbin.social 4 points 1 year ago* (last edited 1 year ago) (2 children)

Yes, there ain't much to complain except for health. After all, vegan isn't a diet, it is an ideology and if meat was the only healthy option, then it would be vegan to sometimes eat animal products and use products that caused harm to animal. In fact, I doubt there is such a thing as a totally vegan as the world is quite harsh. Because veganism is about minimising harm. Anyway, back to the diet, vegans generally believe that meat isn't a necessity for humans thus making this lab meat potentialy unhealthy (according to that belief).

[–] Rekorse@beehaw.org 1 points 1 year ago

Accurate! At the very least fish are incredibly unhealthy. It's funny that most governments recommend that their people limit the amount of fish they eat in a week due to mercury. But fish take all the stuff we dump like chemicals and trash among other things. Farm raised fish are all that plus disgusting and disease ridden.

Basically, all the stuff a pregnant woman is supposed to avoid, like processed meat, EVERYONE SHOULD AVOID.

[–] borkcorkedforks@kbin.social 1 points 1 year ago

Health wise there really isn't a big advantage to being vegan, vegetarian, or a meat eater. People can have healthy or unhealthy diets regardless of particular restrictions. In the past there wasn't a lot of vegan junk food or options so vegans kinda had to be healthy on accident. Now days you can get just as messed up on vegan food. As an example oreos are vegan but no one is going to argue they're a healthy meal.

A complete protein is important but a little more complex to get without meat or dairy. Right now the cheapest protein sources are chicken or protein powder derived from milk (whey). Vegan options are kinda pricey for powder and whole foods would be kinda a pain if you want a higher protein diet. I wonder if they could do "lab grown" complete protein powder cheap.

Arguably the lab grown meat could be more efficient than growing a whole chicken. And a lot of people simply won't give up meat.

[–] ffmike@beehaw.org 2 points 1 year ago

Speaking just for myself, I'll be giving cultivated meat a pass. Not because I'm a vegan, but because I avoid ultraprocessed foods and venture capitalism as much as possible.

[–] twitterfluechtling@lemmy.pathoris.de 2 points 1 year ago* (last edited 1 year ago) (1 children)

As far as I read recently, currently the liquid to provide the cells with nutrition is gathered from slaughtering cattle. I couldn't find the link, will keep looking, but if anyone has information to the contrary, I'd be happy. I love the idea of meat-taste without animal cruelty and I think it is the way we have to go if we as a species want to survive.

EDIT: https://gemeinsam-gegen-die-tierindustrie.org/en/clean-meat-the-solution-to-the-problems/

In any case, it is important to bear in mind that the production process regularly relies on fresh muscle tissue and continuously on growth serum.

The growth serum is usually obtained from the heart of a calf embryo, for which the calves and sometimes the mother cow are slaughtered.9b Some companies state that they have replaced the calf serum with an algae nutrient solution.10 It also remains to be seen whether this alternative will prevail.

As the domain name already suggests ("Together against animal industries"), this article seems heavily biased, however. If tissue of a calf embryo is required for the serum, that's not a calf, but an embryo, which is slaughtered. Just like abortion is not murder.

Nevertheless, I hope the mentioned algea nutrition solution will prove a viable alternative.

This is apparently from one of the companys that Works on cultivated meat.

According to them, they got the animal cell free nutrition working. And use it for their production.

Since its from the company directly, You should take it with just as much of a grain of salt as the other article.

But, they have a very convincing argument:

The bovine cells are the most expensive part of the production, and using them for production purposes would be prohibitly expensive.

As cynical as that take is, to me thats the best argument that animal cell free meat will be the rule instead of an exception for cultured meat.

[–] ilovecomputers@beehaw.org 2 points 1 year ago (1 children)

I remember reading about cultivated meat using fetal bovine serum, so I’m wondering if Upside managed to take out a reliance on livestock for its process

[–] leetnewb@beehaw.org 0 points 1 year ago (1 children)

There is no real way to scale production without eliminating fetal bovine serum.

[–] Rekorse@beehaw.org 1 points 1 year ago* (last edited 1 year ago)

People are posting sources saying that most companies have been serum free for a few years now.
