That wasn't the argument. It was that bees are sentient, and honey has no redeeming qualities.
Eating something with no redeeming qualities may be fine if it doesn't harm a sentient being to obtain.
If it has redeeming qualities, those can in part make up for that harm (which is why I mentioned crickets as more justifiable than honey).

Is it not correlated, or does correlation not equal causation? ;)

I didn't want to get into details here, but I can. Although maybe another thread should be started (or resurrected).

It's also much better for the environment to eat insect protein compared to other animal products.

Insect protein is taken in the first world to replace other animal based proteins by people who believe animal based protein is superior. There's no reason this superiority should be believed to be true, but it is a relatively efficient source of protein and vitamins, particularly for people in the third world where high quality plant protein is harder to produce with their infrastructure, and very difficult for them to process. Crickets and the like can process many otherwise inedible or difficult to eat plant materials that grow where people don't have the know how or infrastructure for superior agricultural practices.

There are actually some good arguments for eating insects, since the efficiency concerns are much less than for other animal products, particularly as a replacement.

Honey production, on the other hand, I do not believe is better for the environment,

This is the core of the issue. Bees produce honey, then the honey is taken away and replaced with sugar and other stuff, which the bees have to reprocess into honey again but which is generally recognized to be nutritionally problematic.
The bottom line is that honey harvesting isn't really about making anything and providing a net yield, it's just swapping something out (which turns out to be worse for humans AND the bees). The modern process is less efficient than just eating sugar. AND, as it turns out, less healthy.

There's no good argument for eating honey. Like sugar, it's relatively useless nutritionally, but it's also filled with potentially dangerous pathogens, less efficient than producing and using the sugar directly, and contains much more fructose, which makes it nutritionally inferior to sucrose from a human health perspective.
Neptual wrote:As for the Colony Collapse there is no proof that the harvesting of honey is directly correlated in that process. [...] It does not matter what you 'expect' but rather what is backed and supported by evidence which in this instance there is none for.
"I expect has quite a bit to do with Colony Collapse." This was more of a footnote, but I can explain in more detail WHY that is the case. I'm not pulling it out of my ass (it's just not very relevant to the topic at hand).

However, this was the more important point:

We need bees to pollinate our flowers and produce a lot of crops, so anything that threatens them I take as a serious problem, particularly when it's completely unnecessary like Honey harvesting.

The fact that over-harvesting of honey may be involved is a reason to stop it, even without proof positive, because honey provides no actual advantages beyond a very slight subsidization of the cost of food from flowering plants (which is not any advantage to vegans, because at best you're taking money from one pocket, and putting it (after the honey man's cut) into the other).

Consider the standards for evidence based medicine. It must be both safe AND effective.
In the case of veganism, at minimum we should be obligated to ask only if something is harmless OR useful.

If something is useful, it may be enough to just show that it's not very harmful, or show that it's unlikely to be very harmful (in excess of its usefulness) -- like medicine.
However, if something is useless, a greater burden must be put on showing that it is also harmless. In the case of honey, that burden has not been met.

See the precautionary principle: http://en.wikipedia.org/wiki/Precautionary_principle
Which applies even more when a practice is useless or worse (as is the case of honey).

Honey is worse than merely useless in that it is actively unhealthy, and yet through misconception and dishonest marketing promoted as a healthier alternative to sugar.
Honey is worse than merely useless in that it is wasteful in agricultural terms. We can produce comparable or superior sweeteners in every regard with greater efficiency than honey affords.

At best, honey may be blameless for CCD, but this has not been proven (and is extremely unlikely, since our practices drastically affect bees lives). We don't really know for sure what's causing it, so anything that might be causing it must be suspect.

http://en.wikipedia.org/wiki/Colony_collapse_disorder
Wikipedia wrote:The mechanisms of CCD and the reasons for its increasing prevalence remain unclear, but many possible causes have been proposed: pesticides, primarily neonicotinoids; infections with Varroa and Acarapis mites; malnutrition; various pathogens; genetic factors; immunodeficiencies; loss of habitat; changing beekeeping practices; or a combination of factors.[9]
The red bold cause is directly related to increase honey consumption and harvesting by humans (and replacement with sugar and other substitutes).
Orange causes are more indirectly related or more speculatively related, including increased exposure/less enzymatic breakdown, and changing the mediums for pathogens that bees are exposed to through food source replacement, inbreeding for production, etc.

Among those, loss of habitat and mites are pretty much the only things that seem unlikely to have any serious direct relation to honey harvesting (I could be wrong on that though).
Wikipedia wrote:A 2015 review examined 170 studies on colony collapse disorder and stressors for bees, including pathogens, agrochemicals, declining biodiversity, climate change and more. The review concluded that "a strong argument can be made that it is the interaction among parasites, pesticides, and diet that lies at the heart of current bee health problems."
Put up the proof that honey harvesting is harmless, or show me proof that honey is a health food. But in either case, the burden of proof lies on the honey advocates.

Hi there, pretty much joined this board for this discussion. Count me among those who eat vegan other than a meal once a week of oysters/mussels.

I personally call the diet "The 95/5 diet". 95% Vegan, 5% bivalves. I went vegan for ethical reasons a few years ago, and have come to the conclusion that there is not a sensible reason to not eat oysters and mussels. I made this decision when it was posed to me that more sentient beings are harmed in plant food production than in oyster and mussel farms. They are also environmental and nutritious. Their B12, Omega 3, and Zinc content allow me not have to supplement within my diet. Sure they are high in cholesterol, but since 95% of diet is cholesterol free, I think it's a good tradeoff.

Props to brimstone salad for their tremendous reasoning on this issue! I'm almost completely closeted in my oyster/mussel eating, so am hoping this can get more mainstream steam within the vegan community so I no longer have to hide my dirty secret in the dark! :lol:

Look forward to discussion, and excited to find a community who aren't intellectually frightened by this idea.

Hey, welcome to the forum!

I agree that there's nothing wrong with consuming bivalves, but you might want to consider the health issues.

Even though you aren't eating a lot of cholesterol by eating oysters and no other animal products, it unfortunately has relatively the same impact on your health as eating a lot of cholesterol: viewtopic.php?f=7&t=992&p=10429&hilit=C ... rol#p10429

There are still health arguments to be made (Oysters contain Heme Iron, and are high in methionine, as well still contain cholesterol which is still a problem despite myths to the contrary), but if they're rope grown, there's probably little to no ethical or environmental argument against it, except possibly if you do not live near the coast (shipping and distribution of oysters inland likely being more of an environmental issue than with beans for cultivation and distribution).
Mr. 95/5 wrote:I made this decision when it was posed to me that more sentient beings are harmed in plant food production than in oyster and mussel farms.
Both are at negligible levels. It's really not clear which is higher since there's not data on this. It could be one way or the other, this would have to be a matter of legitimate research, we can't really assume.
Mr. 95/5 wrote:Their B12, Omega 3, and Zinc content allow me not have to supplement within my diet.
No, no, and kind of. These are all in oysters, but in wildly different amounts.
Oysters DO contain a hell of a lot of Zinc, but not much Omega 3 since they're pretty low in fat in general. If you tried to get all of your Omega 3 from oysters, you could be consuming a potentially dangerous amount of Zinc, as well as Heme iron (you'd be at over 200% a day).

Zinc is probably the best argument to be made for oysters, since you'd need to consume so little of them for a boost if you're low (something that's not hard to get enough of by eating a lot of beans).
However, you still need a plant based Omega 3 source.

Oysters also don't contain enough B-12 that eating them once a week will guarantee you optimal levels, unless you're eating an absurd number of them. You'd need about two small canned oysters a day for a mere 100% of your B-12 (half an ounce), though 25-100 mcg a day is really recommended, and absorption gets worse the more you eat at once.

http://veganhealth.org/articles/dailyrecs

1,000 micrograms is the recommendation for twice a week. If you're only getting it once a week, absorption is going to be even worse.
You would need to eat about 3,000 calories of oysters once a week to even hit 1,000 mcg. A feat likely impossible for most people. And that's still not meeting recommendations.

Just take a supplement, it's much easier. Or if you really prefer to get your B-12 from oysters, you need to be eating them every day, not once a week.
You don't need as much every day, because the less B-12 you eat at a time, the better you absorb it. 0.5 oz for the minimum (not recommended), or 5 oz a day of oysters should reach supplementary levels of B-12, although also a concerning amount of Zinc and Heme iron.

I would recommend not more than 0.5 oz oysters a day, and take a B-12 supplement twice a week.
And, of course, find a good plant source of Omega 3.
Mr. 95/5 wrote:Sure they are high in cholesterol, but since 95% of diet is cholesterol free, I think it's a good tradeoff.
Yeah, but it's not... unless you're a male porn star and really need a LOT of zinc. ;)
Because you're not getting anything you couldn't get from beans, nuts, and a very cheap supplement, and cholesterol isn't the only problem, the cost benefit tradeoff isn't necessarily in their favor.

Thanks.

I just want to make clear that I don't think it's necessarily healthy or a silver bullet for fixing vegan nutrition, but I do appreciate it as a way to undermine dogma, and show that vegans care about ethics and sentience, rather than arbitrary lines.

Interesting. What about mussels? According to nutrition data, 6 oz of mussels have 700% of your B12 %DV as well as 1500mg of Omega 3s (at an outstanding ratio better than 20-1).

Mr. 95/5 wrote:Interesting. What about mussels?
About the same as oysters. Not significantly more b-12 or Omega 3 in terms of a dietary source (just slightly more, but still very little).
Mr. 95/5 wrote:According to nutrition data, 6 oz of mussels have 700% of your B12 %DV as well as 1500mg of Omega 3s
I think you meant 1700% B12. That's not much for a single dose. Look at the micrograms.
Oysters have about 1300% for the same amount, and 1100mg Omega 3. That's not much in either case.

6 ounces is a lot of oyster (or mussel), almost half a pound. Eating a realistic amount of oysters or mussels a day is not something that's going to provide a reliable source of those things.
The difference in mussels is they don't even contain a large dose of zinc.

How many oysters do you usually eat?
Mr. 95/5 wrote:(at an outstanding ratio better than 20-1).
And roughly 1:1 to saturated fat.
It doesn't really matter what the ratio of 3:6 is when it has so little overall fat. It will be overwhelmed by any other fat you eat.

You only need to care about the ratio in larger fat sources in your diet. If you're looking for Omega 3, go for high omega 3 nuts and seeds: flax, hemp, chia, and walnut. Those offer much better fat sources.
Canola oil is a good option too, if you're on a budget.

The 700% was percentage of daily value.

I'm not sure what you are comparing them too? Mussels have some of the best Omega 3/6 ratios out there, and with significantly more Omega 3s than steak, chicken, turkey... Oysters have some of the best b12 per calorie of any food according to nutrition data. 2 oysters essentially give you your RDA for B12. I mean, can you give some examples of food that are better sources of B12 and Omega 3s (EPA and DHA) than mussels and oysters? Particularly ones that are suitable for vegans (if we agree there isn't an ethical reason not to eat mussels)?

I can understand knocking them for being high in cholesterol or their poison risk factors thanks to pollution, but you can't tell me that they aren't loaded with nutrition that would be incredibly helpful for vegans...

In 6 oz. of mussels I'm seeing 1700% DV. Maybe it's variation in the source.
Mr. 95/5 wrote:Oysters have some of the best b12 per calorie of any food according to nutrition data. 2 oysters essentially give you your RDA for B12.
Only if you eat two of them every single day. As I explained in an earlier post, it's not the same if you eat it once a week in a larger amount. Absorption is not linear, but more logarithmic. The more you eat at once, it has diminishing returns for absorption.

The problem with oysters or mussels is not their density of B12 per calorie, but the physical volume of them to get a significant amount, particularly if you're eating them once a week, and the other bad things that come with that kind of dosage.
Mr. 95/5 wrote:I'm not sure what you are comparing them too? Mussels have some of the best Omega 3/6 ratios out there, and with significantly more Omega 3s than steak, chicken, turkey...
Land meats have terrible ratios, and they also have high amounts of overall fat which makes that even worse.
As I explained before, oysters/mussels are fairly low in fat, which makes the 3:6 ratio irrelevant. AND if you eat enough Omega 3 from oysters or mussels, which would be a huge amount of them, you'd also end up with a very large amount of saturated fat, which is in about a 1:1 ratio with Omega 3.

You need high fat food with a good ratio.

Low fat food with a good ratio is functionally useless. High fat food with a bad ratio is bad.
Low fat food with a bad ratio is fine, because it's low in fat anyway so the bad ratio won't throw off your overall numbers.

6 oz Mussels:
1.6 g Omega 3
0.3 g Omega 6
1.4 g saturated fat

6 oz Walnuts:
15.4 g Omega 3
64.8 g Omega 6 <- This is still OK.
10.4 g saturated fat

The same weight of Walnuts contains much more Omega 3. You'd have to eat almost 60 oz of mussels to get the same, and then you'd have around 40% more saturated fat in the process.
There's no reason to believe that a 1:4 ratio isn't perfectly fine.

And Walnuts are the worst nut I listed.

6 oz of ground flax seeds:
38.8 g Omega 3
10.1 g Omega 6 <- This is even better than OK, but a higher ratio is not much better, you DO need Omega 6 in your diet.
6.2 g saturated fat

The same amount of flax contains even more Omega 3 than Walnuts. You'd have to eat almost 150 oz of mussels to get the same. Over 9 lb, or over 4 kg of mussels, and almost 34 grams of saturated fat. You'd also get about 7,000 calories, and a likely dangerously high amount of heme iron in excess of 3,000% of your DV.

The Omega 3:6 ratio in a food is not the only important thing. If it's low in fat to begin with, it's actually one of the least important things about the food.

Mr. 95/5 wrote:Oysters have some of the best b12 per calorie of any food according to nutrition data.
Muscle meats are poor in B12. Organ meats are better per calorie than oysters. They're also MUCH better by weight. But that's irrelevant: You can get a much more reliable and lower calorie dose from supplements, which were made directly from the bacteria which produce B12. Also much cheaper, and no cholesterol or saturated fat.
Mr. 95/5 wrote:I mean, can you give some examples of food that are better sources of B12 and Omega 3s (EPA and DHA) than mussels and oysters? Particularly ones that are suitable for vegans (if we agree there isn't an ethical reason not to eat mussels)?
Supplements: B12 from bacteria in pill form, and DHA from algae (if you want DHA specifically). There's even less evidence of benefit from EPA.
For Omega 3 in general, go for nuts and seeds.

How much do you spend on what amount of oysters each week?

You don't have to supplement on DHA unless you're pregnant, though, if you're getting enough Omega 3 and not overloading on Omega 6. The body is capable of converting these things. Omega 3 is essential, but those particular forms are not.
Mr. 95/5 wrote:but you can't tell me that they aren't loaded with nutrition that would be incredibly helpful for vegans...
I'll give oysters zinc, but I'm just citing their nutrition data. Yes, they have these things in them, but they are in wildly different ratios, and they come with a lot of negatives too.

The best usage of oysters are for people who do not have access to supplements, or for young people (like teens) who want to go vegan but whose parents insist they eat some animal products. They are probably most useful as a token animal product to contradict arguments of dogmatism. Nutritionally useful though? Not so much. Not if you have access to beans, nuts/seeds and B12 supplements. They're still animal products, and still have most of the same nutritional drawbacks of animal products.

If you like them and you want to eat them, though, go ahead. :)

In regards to your points about needing to supplement B12 in larger doses if you are ingesting B12 only once a week:

1. I am getting plenty of B12 in other sources such as in fortified soymilk and nutritional yeast, so it's not as though I am void of B12 the other 6 days of the week.

2. I was told by a vegan doctor that a B12 deficiency takes years to develop. That doesn't exactly mean your point can't be true, but I highly doubt I'm going to develop a b12 deficiency when I'm getting solid amounts in fortified forms as mentioned above, in addition to a high dosage once a week via mussels/oysters. There are plenty of vegans who get their B12 in large doses via shot form as well.


To be clear: I am not stating that I don't ingest b12 or omega 3s in other forms nor should someone rely exclusively on oysters and mussels for their b12 and omega 3s. Rather, in conjunction with an otherwise healthy and balanced plantbased diet, eating mussels and oyster once a week is sufficient enough in order to avoid supplementation. That is the point I'm making.

Be careful about nutritional yeast. It's excellent, but it isn't all fortified. It's really still safer to just supplement so you don't have to worry about it.

That said, if you're certain that you're eating enough B12 from fortified vegan sources the rest of the time, aren't the oysters kind of superfluous?
Mr. 95/5 wrote:2. I was told by a vegan doctor that a B12 deficiency takes years to develop.
This is correct.
Mr. 95/5 wrote:in addition to a high dosage once a week via mussels/oysters.
But you are not getting a high dose once a week. You are getting a modest dose once a week, and likely a modest dose the other six days if your nutritional yeast and soy milk are fortified. Your nutritional yeast and soy milk may contain more than the oysters, depending on how much you're eating and if you've confirmed they're fortified.

Why are you so against a small chewable usually fruit flavored pill once or twice a week?
Mr. 95/5 wrote:There are plenty of vegans who get their B12 in large doses via shot form as well.
That's totally different. Shots circumvent gut absorption. However, it's much safer to just take a supplement, a shot can inadvertently hit a nerve, even if professionally administered (the chances are small, but the risk by oral route is virtually zero).

Am I correct in assuming you are digesting, rather than injecting the oysters? ;)
If that's the case, they are subject to the same diminishing returns, which makes a slightly larger dose than you get the other days not really more useful.
If you're trying to get some significant portion of your B12 all at once, you then want a meaningfully larger amount absorbed, so you need a huge dose which oysters do not provide -- pill based supplements do.
Mr. 95/5 wrote:To be clear: I am not stating that I don't ingest b12 or omega 3s in other forms nor should someone rely exclusively on oysters and mussels for their b12 and omega 3s.
Then I fail to see what benefit these oysters are offering you in terms of B12 or Omega 3. They have a lower density of Omega 3 than nuts and heart healthy oils like canola. They don't contain particularly much B12, and you could have just had soy milk and fortified yeast that day too, to pretty much the same end.
Oysters once a week aren't likely to save you from deficiency if you diet isn't otherwise adequate, and if your diet is otherwise adequate then you don't need the oysters once a week. It seems like you're trying to claim both, that your diet is otherwise adequate but you need the oysters anyway (why?).

If you want a real safety net for your diet, built it from sturdy rope (pill supplements), not tissue paper (oysters).
Mr. 95/5 wrote:Rather, in conjunction with an otherwise healthy and balanced plantbased diet, eating mussels and oyster once a week is sufficient enough in order to avoid supplementation. That is the point I'm making.
You aren't avoiding supplementation, though. You're eating fortified foods which have been supplemented with B12, which would also have about the same effect without the oysters. You just aren't chewing up a tiny and delicious fruit flavored B12 pill, which is far from an exciting claim.
I still fail to see what the point of the oysters is at all, and how they are benefitting you nutritionally.

If you like them, that's fine. I'm not about to criticize you for eating something probably non-sentient and environmentally sustainable for enjoyment, but I hope you do so with all of the information rather than going ahead with it under a misconception that you need it or it's offering you a meaningful health benefit.
