To be honest, I don't get the mania for processed meat substitutes when there's excellent vegetarian/vegan fare from cuisines that have been doing it for millennia. As an Indian brought up in a vegetarian family, I had no inkling or desire to eat meat until I came to the US for grad school. One day I had this niggling doubt that I continued to be a vegetarian for cultural rather than ethical reasons. I tested that hy…

> To be honest, I don't get the mania for processed meat substitutes...

It seems you didn't even bother to read the article to check if it would make good segue into your vegan epiphany story: there is no mention of processed meat substitutes.

It also seems like the hamburger you tried was quite poorly prepared if hot dogs made a more compelling case for eating meat.

Before anyone goes vegan, check-out the numerous ex-vegan videos on youtube. Even with supplementation veganism isn't sustainable for most people past 3 years, 10 if you're lucky, very few get to 15. Just keep in mind that without vitamin B12 supplements-->certain death. This is not a human diet, and humans are not herbivores. Herbivores have complex stomachs or eat their own poop (eg, gorrillas and rabbits). After t…

You should read the nutritional guidelines of whichever country you are from instead of listening to some misinformed youtubers with low testosterone and high blood pressure.

>At least a plant-based diet reduces your GHG footprint That isn't actually true. It is a very misleading claim spread to promote veganism. It comes from comparing the raw caloric value of field corn, to the caloric value of beef. In reality, We do not actually eat field corn, we turn it into HFCS and corn oil, this reduces the energy efficiency of corn dramatically. A plant based diet also should not be based on HFC…

That's interesting. I based my opinion on reports such as [1]. Do you have any (semi-)scientific references that support your opinion? I agree that we don't eat much corn directly, but if it weren't used to feed livestock, we could use the land for something else, like potatoes or lentils or whatever grows in similar climate to corn, which are actually eaten. I'm somewhat doubtful of your claim that corn fed chicken…

>Do you have any (semi-)scientific references that support your opinion?

Does arithmetic count? The stats are available to look up yourself, the math is simple to do. But there's nobody funding publishing "debunk vegan nonsense" papers like there are people funding "make up vegan nonsense". So the only people you can find doing the math for you are just random people like the blog I link to later in this post.

>I agree that we don't eat much corn directly, but if it weren't used to feed livestock, we could use the land for something else, like potatoes or lentils or whatever grows in similar climate to corn, which are actually eaten

Most of those alternatives produce far fewer calories per acre than corn, which is the issue. An honest comparison shows most plant crops produce very low calories per acre, and require lots of diesel to produce and transport. Yes, you could grow something else. And almost all of those something elses are worse than corn fed chicken from an energy efficiency standpoint. If vegans want to argue the impact of meat vs plants in this way, then they need to apply the same standard to plants, and that means demanding that the vast majority of crops being grown are abandoned in favor of the tiny number that meet corn's energy output: corn, sugarcane, potatoes, palm. There's your acceptable vegan diet if we're going to limit things for being less efficient than corn.

>The usual rule of thumb for going up one level in the food chain is that you lose 9/10th of the energy

We're not talking about a natural ecosystem, which is what that rule of thumb is for. We're talking about animals that have been bred specifically to grow very large very quickly on very little food.

>and corn only produces on the order of 12 million calories per acre

No, corn produces 12 million calories per acre in human edible calories when converted to corn oil and HFCS. It produces 15 million calories per acre as livestock feed.

>This random google result here [2] indeed claims about 1.4 million calories per acre for chicken.

And it is very wrong. It is making up a silly number by using the human figure for corn calories per acre not the livestock feed figure. Then assuming chickens are fed 50/50 corn and soy when in reality their feed is almost entirely corn. It is also assuming a feed conversion ratio of 3, which is nearly double the actual ratio of 1.6 https://en.wikipedia.org/wiki/Feed_conversion_ratio#Poultry

Here's a post that shows math for why this vegan meme is wrong: https://bovinepracticum.weebly.com/ruminations/the-beef-vs-v...

And during plant collection lots of animals die: - rodents die in wheat field during harvest - recently there was an article on HN of olive harvests killing hundreds of birds - entire forests are destroyed with wildlife by burning to grow palms for palm oil

Right. And raising livestock requires more plants to be grown to feed them, so even more animals die to grow the feed.

Pasture is not harvested or stored, so there is no rodent or bird deaths from harvesting equipment, and no mass rodenticide usage as there is with grains.

It is far from "loaded". 0.15g per serving is not "loaded", and is half the level of salmon for example, which is promoted as healthy. Omega 6 polyunsaturated fats are highly inflammatory. But our intake is almost entirely from "vegetable oil", not chicken.

Chicken and eggs provide by far the most arachidonic acid in the typical diet: https://epi.grants.cancer.gov/diet/foodsources/fatty_acids/t...

That's because people eat a lot of chicken and eggs, and don't each much salmon. When deciding what to eat, the amount per serving is what matters, not how much of it the average person eats. And again, arachidonic acid is just one omega 6 PUFA, being specifically singled out for promotion by vegans because it is found in meat. The rest of the omega 6s are all just as bad, and our intake is almost entirely from vegetable oil. A serving of chicken has less than 2g of omega 6s in total. That's less than of the omega 6s in a serving of tofu.

“Animals eating other animals is natural evolutionary behavior.” Whether something is “natural” has no bearing on its goodness. And certainly plenty of the behaviors that cause human suffering are 100% natural. “If carnivore animals has the same concerns and turned to tofu, they’d be dead.” We’re not obligate carnivores so this is a non-sequitor. “Let’s concentrate on the suffering of our fellow human beings...” This…

> Whether something is “natural” has no bearing on its goodness. Well, goodness also is not a logical argument. Good according to what, some arbitrary morals? Other people find it perfectly good to eat burgers. > And certainly plenty of the behaviors that cause human suffering are 100% natural. Only in the contrived sense, that we are part of nature as a species. But we have long made the distinction that our more ad…

“We have long made the distinction.....”

Rape, murder, and infanticide are all natural human behaviors by this definition, and they’ve become less common as we’ve become more divorced from nature. Also natural: having about half of your children die what are now preventable deaths. Life in nature is complete shit.

And I was assuming here a basically utilitarian definition of the good, because of your concern with suffering. Of course it’s debatable.

That site is run by a well known quack, and is full of misrepresented "evidence" and even outright lies. It used to be called the "vegan research institute" until he renamed it so it was less obvious as a propaganda outlet. https://sciencebasedmedicine.org/death-as-a-foodborne-illnes...

"Well known quack" sources ? And btw you linked an article with the following conclusion : "The video confirmed what I already knew from evaluating the published evidence: it is healthier to eat more plant-based foods and less red meat."

https://mediabiasfactcheck.com/nutritionfacts-org/

>And btw you linked an article with the following conclusion

Yes. The point is that even plenty of vegans, who agree with his premise, know he openly lies to promote veganism.

That’s just a blog post on Harvard.edu domain. Has no cred on its own. Not backed up by scientific references. Please post sources. Thank you.

>just a blog post on Harvard.edu Which is more authoritative than a comment on HN. I believe it’s on you to find a more authoritative source that contradicts the above.

Blog posts and HN posts have an equal lack of authority. Authority does not matter though, facts do. You can look up the levels of oxalates, phytates, PUFAs, etc from whatever source you like and confirm reality. You don't need an "authority" to tell you what to think.

I don't believe that this matters. Why would it? Offal has great nutritional value. The inuit did perfectly well on an all-meat diet. The issue is more likely curing with nitrites and smoking. >It's like eating a fruit vs drinking a juice Another thing that doesn't matter.

>Many things happen and none of them are magical. The glycemic index of a raw fruit isn't the same as a juice from the same fruit for example, you don't get the fibers, &c.

Only if you buy a juice concentrate. Making your own juice is equivalent to chewing an orange.

>You're free to believe what you want. A slime of chicken skin, fat and ligaments isn't digested the same way as a chunk of chicken breast. The nutritional values are just a small part of a big equation.

Of course not, I'm not arguing for that. What I am arguing for is that there's nothing inherently unhealthy about eating any of those things, and that offal is actually very nutritious.

>That's another side of my point, they evolved on that diet, most people didn't. Do you think the lifestyle of the average first worlder has anything to do with inuit lifestyle?

If an American adopted the diet of an inuit in such a way that their caloric needs are satisfied then I doubt it would matter. It is definitely possible that the inuit have evolved in some ways to accomodate for their diet, do you have any sources for that?

You'd think that the meat industry would pay for debunking vegan nonsense papers, especially when the world starts talking about a carbon tax that would make beef a lot more expensive if they use the numbers I cited. But I'll read the links you provided and update my opinion. Thanks for looking them up for me.
