Actually, I was taught that predators have distinctly different digestive systems to herbivores and even omnivores (despite it being controversial to claim humans belong in this category) back in primary school. It's ok if you're education system is not on-par with more modern civilizations, we're all here to learn after all.

Stress hormones are carried via blood right? Animals overproducing stress hormones and it ending up in the meat doesn't sound that unreasonable.
I doubt those hormones survive the whole digestion process when you eat it though.

It's just adrenaline, which is usually caused when we're afraid, however if absorbed from food it would lead to anxiety problems, and undue depression. Currently sieving through some hippy sites to back up my points to pacify the more veracious members.
But you're right, it only really harms you if you eat meat frequently and I supposed in large quantities, not to mention each individual absorbs different minerals differently.

It really seems like I'm not the one with the inferior education..... So basically, your common sense tells you that although almost all prey die in fear in nature, farm animals who relatively die much faster infects only us, humans with fear because fear itself is carried with blood and again our digestive system is not immune to that.... whatever passes with blood?

More consistent fear over time (e.g. isolation and tight quarters and **** that industry animals suffer) would obviously create more stress hormones than an animal that leads a relatively stress-free life before being killed.

What I'm saying is what is bad for us may not necessarily be bad for predators, assuming that adrenaline hits us the same way that it hits predators.

He says adrenalin. It does not work that way, on the contrary, adrenalin rush, it does not accumulate over time.

It doesn't accumulate in the blood, that would eventually kill the animal, but it might accumulate in the meat.
I say might here cuz I honestly have no idea. Haven't really thought about it before.
I still think our digestion system would take care of it if it exists.

adrenal gland. different chemicals get locked in the meat. it makes no difference, ultimately. although, i can say that grass-fed meat tastes better than grain-fed. happy cows make for better meat.

Common sense. Life experience, but if you want me to dig through the web for a scientific source then I'll leave you disappointed, I saw what they did to the animals, and I refuse to believe that the crap they gave them and the adrenaline from fear will not pass unto whomever eats them. As I said, I discerned it from common sense and what I know of how bodies work.

Common sense? My friend, this is filled with so much ignorance of chemistry and biology that I straddle the fence between laughter and sorrow. But let's start with this: you could take pills of pure adrenaline yourself and it probably wouldn't do squat to you since the oral bioavailability of the stuff is practically zero. On top of this, the half-life of adrenaline in a living organism is about 120 seconds, so, well... <sigh>
Maybe you shouldn't be getting your science information from food blogs?

hey cor, you're a scientist/chemist, you might know the answer to this. what exactly ARE the chemicals that get locked into the muscles? is it lactic acid?
the reason i ask is, when you are tense, and you go and get a massage, they tell you to drink plenty of water afterward, to wash out the "toxins" that were trapped in the muscles, making them stiff, and then released into the bloodstream by loosening up the muscles. to me, the "toxins" idea sounds like mumbo-jumbo, i would assume it is actually a variety of stress chemicals(i'm not talking about adrenaline, just stress chemicals). am i right or wrong in this?
or is it more similar to what they described in the military, through physical fitness, where a muscle that is unused, develops a film of hardened cells over the muscles, that can snap/hurt/cause damage when they aren't stretched and exercised enough?
are either of these correct, or are they merely propaganda to sell their ideas of massage, stretching, and fitness?

My advice is that any time someone starts talking about mysterious or ominous 'toxins', it's time to start walking in the other direction.

yeah, that's what i figured. thing is, i find myself getting a headache if i don't drink a lot of water afterward. so, there's obviously something that is released into the bloodstream, a buildup of some chemical(s), that isn't really good for you, when you get a good massage.
eh, what the hell, i'll google it.
-------
ok, i'm getting that it is a combination of salt and lymphatic drainage, that needs to thinned with water to help the kidneys process the waste matter released through massage. why couldn't they just say that, instead of "toxins"? makes them sound like hippies. next, they'll be telling me about the healing power of crystals.

I love eating meat...but I think I'll pass on lab-grown meat. It just doesn't sound right or gives a ring to my ears. Too inorganic and chemical.
Real meat is the best!

It would have been an honour to be among the first to try this new meat as it may very well be the key to saving the planet(or more like saving humanity). I am not a meat enthusiast but I still love it. But lab meat is bound to become much cleaner, tastier, cheaper, more humane, more eco-friendly and better texture than animal meat if scientists can learn to master this. Life is going to be greeeaaat in the future!

Thanks for clearing that up Cor, I guess I'll drop the adrenaline argument till I have something more to work on. What do you reckon about the hormones that cows are fed, namely estrogen, would these have any effect on a human consuming them? The point that I'm trying to make is that living conditions and treatment of animals with various drugs will affect the finish product, and those consuming it, meaning that we have a problem to deal with that's more dire than just a moral question. I've looked at dark cutting, but that does not occur enough to be a commonplace problem, (or maybe it does, but in most cases it doesn't render the meat "sub-par" which is anything below muscle PH 5.6).

It's hard for me to speak generally because I haven't researched the issue, but I do know that no research has shown that milk from hormone-treated cows is any different from those which are not so-treated.
The thing is that people form beliefs about food in complex ways. They have a fixation on 'natural', although research has had difficulty honing in on what 'natural' really means to consumers. They also have a fixation on 'chemicals', even though pretty much everything is a 'chemical'. They have trouble with dosage concepts and primarily form their risk perceptions based on emotion and cultural values, even if they often wrongly ascribe it to common sense and logic. I've actually published articles in the peer-review literature related to this topic and find it endlessly fascinating.

Well, at least people will finally shut the **** up about whale meat.
No, seriously though. This is going to expand all sorts of possibilities for the pallet, is it not? Couldn't you theoretically grow whale or porcupine meat or something just as easily? I can tear through a heavy protein porcupine steak without any of the fat involved. I never was a big fat fan, except you need a little for dat der flavor.
lol @ the doom-sayers worried about living space in the immediate future. If the cost of this technology is able to be successfully driven down to a mass commercial level(which will indeed be a big obstacle. Scientists can do all sorts of fun **** in a lab, but a lot of it doesn't count for jack on a commercial level because it's not even close to easily & cheaply replicable) Cell phones were invented in the 1940s, but that didn't mean people started using them everywhere) it's going to have a huge impact on the world. We'll no longer be so heavily dependent on the North American and Central Asian food belts. You can grow cattle meat in New York and be like "**** yea".
