There was one study with 99 participants. A counter argument is Asia, where men eat a lot more soy and don't have reduced sperm count.

They've also eaten soy for much longer than others, literally thousands of years(1) at this point. That's more than long enough to evolve countermeasures if it did have an effect. They also eat soy differently, mainly in products which are fermented.

I think a lot of it comes down to how it's processed... fermentation probably made it safer to consume over time.

I think the aversion to dietary fat for the past 3 generations combined with refined seed/bean oils has been hugely detrimental to human health as well. Not to mention, even with reductions, we still consume a massive amount of sugar per capita compared to pre-wwii levels.

Re:Falling sperm counts, declining egg quality, and endocrin... by jonplackett on Tuesday February 23, 2021 @09:59AM (#26238012)
It’s crazy isn’t it. So many foods they market as ‘low fat’ they just took out the good fat and replaced it with sugar- which your body immediately turns into fat anyway, and messes up your hormones and insulin sensitivity along the way.

And the only oil we’ve introduced into the diet is trans fat which the body mistakes for good fat and just starts building stuff with it, and then it all breaks down and you get heart disease.

You couldn’t make it up

Re:Falling sperm counts, declining egg quality, and endocrin... by User23 on Tuesday February 23, 2021 @08:29AM (#26236981)
Refined seed oils are synthetic chemicals that just happen to use seeds as a feedstock in a relatively novel chemical reaction.

Yes one can quibble that cooking is a chemical reaction, but it’s one that is both simple and that we’re long since evolved to tolerate.

I stick to mechanically produced vegetable oils and animal fats. It’s not only healthier but it tastes better too.

However, a healthy diet depends a great deal on your race. A traditional Inuit diet is observably healthy for Inuit persons, but probably best avoided by people like me. However there are no humans that are evolved to eat seed oils.

I am cautious about these sorts of issues and typically buy the least processed oils (and foods in general) that I can find, however it is my understanding that humans around the world have been producing and eating (mechanically expressed) sesame seed oil for thousands of years. I can't say whether that has any impact on whether people are "evolved to eat it", but it's certainly not something new: https://link.springer.com/article/10.1007%2FBF02859136

Re:Falling sperm counts, declining egg quality, and endocrin... by souprock on Tuesday February 23, 2021 @09:37PM (#26245963)
There isn't any "chemically extracted" seed oil, at least not with a chemical reaction. The use of a chemical reaction is indicated by "interesterified" or "hydrogenated". That isn't used for extraction; it alters the melting points.

The use of solvents to extract oils isn't a chemical reaction. It's not really different from using CO2 to extract caffeine from coffee, using water to extract tea from tea leaves, or using alcohol to extract vanilla flavor from vanilla beans. The common solvent for oil extraction is hexane, which is removed by boiling it off with a vacuum and/or heat.

The solvent-extracted oil will have unmodified molecules. The proportions of the various molecules may differ because the ease with which they are extracted will depend on the processing conditions. You get different proportions of molecules in the mix if you change the temperature, pressure, time, or solvent. For some use cases you might prefer one mix or another. You could get a different viscosity, melting point, or smoke point.

Almost 95 percent of the soybeans grown in the U.S. are genetically modified.

https://www.thedailymeal.com/travel/8-most-genetically-modif...

In 2007, over half the world’s soybean crop was genetically modified; a higher percentage than any other crop.

https://worldofgenetics.weebly.com/genetically-modified-soyb...

Asians are probably eating less GMO soy (than Americans) and we don't really know what those genetic modifications do in terms of human health. They are typically made to improve profit in some fashion, not to improve human health.

> They are typically made to improve profit in some fashion, not to improve human health.

The main goals of GMOs are to increase yield and protect against disease / pests, which is practically the same goal we've had for thousands of years of crop domestication. Take for instance wild pre-domesticated maize vs present day non-GMO maize[1] and you'll see what "natural" crop selection does. Not only do we select for strains that are healthier and with more defenses, we also select strains that give us more bang for buck. Over the years, we've also selected for: texture, size, adaptability to different climates and soil compositions, lower concentration of toxic compounds, etc. Cassava and potatoes, for instance, can be deadly in their "natural" variety, and needed some "help" to get to the varieties we eat today. GMOs are simply the result of applying modern science in combination with what we've learnt from different cultures over thousands of years, to speed this process and hopefully prevent famine and starvation.

I'm not saying all GMOs are good for you, but I just wanted to counter this idea that we don't know what effects GMOs have on us -- we've been eating GMOs for millenia. Edit: I should also strain that I fully support questioning GMOs and holding them to a high standard as a society, especially when the modifications are made for reasons which are to a high degree simply for profit. One example of that would be crops that are engineered to be infertile / yield no seeds.

PS: I'm more concerned about chemical pesticides, especially in the scale at which they're used. Microplastics, heavy metals, soil depletion, etc. Many modern agricultural practices are not good for the environment, objectively speaking. But I wouldn't just blindly lump GMO in the same group just because it's also modern.

That's a little like saying "There's zero difference between traditional animal husbandry and cloning."

Sorry, I think there is a meaningful distinction between traditional human intervention in plant varieties and the more recent intervention called GMO. Most of the world seems to agree that there is a distinction, enough so that we invented new language for what it is we are doing.

Edit in response to your edit:

That's an ugly thing to say and it's not far from a personal attack. There's no blindness on my part. I'm not lumping anything in just because it's modern.

I have a genetic disorder and pay enormous attention to the details of my diet because of it. I react poorly to soy products. Research and experience suggest that my firsthand negative experiences with soy may be related to the fact that most soy in the US is GMO.

My views here have nothing at all to do with unfounded assumptions, ridiculous neurotic views of "modern" things or anything of the sort.

Re:Falling sperm counts, declining egg quality, and endocrin... by DoreenMichele on Tuesday February 23, 2021 @07:11AM (#26236380)
I'm not romanticizing anything.

GMO is relatively new. We know a thimbleful of information about nutrition and health generally. We know even less than that about what more recent inventions do to the human body because there is simply less of a track record and time span in which to determine meaningful data and conclusions.

Saying "We don't know what this new thing does to our health" in no way romanticizes anything. It doesn't even implicitly suggest we know a heckuva a whole lot about the old thing. But the old thing is probably not going to randomly open up some metaphorical worm hole to some bizarre outcome and maybe the new thing will and we just haven't had enough of a track record to notice yet.

Thalidomide was briefly prescribed to pregnant women for nausea until they began having babies missing limbs because of it.

> Sorry, I think there is a meaningful distinction between traditional human intervention in plant varieties and the more recent intervention called GMO.

One is a semi-random process where an unknown (but large!) number of genes are modified in the hopes of getting a few desired good traits to express themselves.

The other is a targeted change to the smallest number of genes to get a single desired good trait to be expressed.

Imagine you are going in for surgery to remove a lump, and the doctor tells you there are two options, he can cut out 20 lumps of flesh, and good chance he'll get the one you want removed, or he can remove just the lump that is causing a problem.

Which of the two options would you choose?

GMO is the later. Traditional breeding is the former.

If people want to criticize WHAT modification was done via GMO, great! Lots of good debate there, maybe inserting some particular gene is a bad idea. But let's have that discussion, not "all GMO is bad!"

Because "all GMO is bad" is nonsensical. GMO isn't some process that turns food into poison. It just changes it, in a more controlled way than breeding changes it.

Evolution and selective breeding don’t arbitrarily modify DNA. The actual methods are small random changes, copying from some other location possibly backwards, or removing segments. GMO significantly expands what kinds of changes are possible.

In practice the difference is generally not that significant, but there is some increase in risks.

Personally, I would prefer a different label for new GMO foods. Presumably, the odds of finding an undiscovered issue drops over time. So using a different label for the first 20 years is reasonably appropriate. Plenty of people are going to take slightly higher risks, so they can benefit from and thus test new cultivars.

Except for random mutations, which are, well, random changes to DNA.

Re:Falling sperm counts, declining egg quality, and endocrin... by Retric on Tuesday February 23, 2021 @03:22PM (#26242395)
Small random changes yes, but long specific sequences become exponentially less likely. People on the other hand can decide to add say the first 100,00 digits of Pi or some other marker for internal use. Picking a useful sequence is hard, but we have the technology to add any specific sequence as long as the plant can survive it.

So it’s not just a question of random chance adding something harmful at this point, but also malicious actors. Someone could easily decide to try and reduce the human population by reducing fertility or whatnot and new GMO crops aren’t tested for such things.

Re:Falling sperm counts, declining egg quality, and endocrin... by Nasrudith on Tuesday February 23, 2021 @11:53AM (#26239550)
Do you know how they discovered methods of genetic modification? Retroviruses in nature. Look at HPV for one as a cause for cancer and the number of viruses embedded in human DNA. Evolution includes all of those.

Of course /nothing/ meets the goal posts of "arbitrary" including state of the art genetic modification.

Re:Falling sperm counts, declining egg quality, and endocrin... by Retric on Tuesday February 23, 2021 @03:04PM (#26242175)
We have moved past simply copying and pasting DNA and can now add arbitrary genetic sequences to any organism. Natural rice retroviruses are unlikely to carry jellyfish DNA let alone something designed from scratch.

As I said it’s probably not that meaningful of a difference, but malicious actors have serious tools to work with here not just random changes.

My apologies. When I added the "blindly lump ..." sentence, I didn't wasn't replying directly at your comment, but rather in reference to the worrying trend amongst anti-gmo movements to lump any GMO related practices in the same basket.

> That's a little like saying "There's zero difference between traditional animal husbandry and cloning."

This is a very interesting topic, actually! I can't comment on animal husbandry (much less dolly style cloning), but cutting (cloning) is a very common way to propagate crops, and has been done for longer than we care to know. It's also the natural way in which some plants and fungi propagate. There are many benefits to cloning, but there are also downsides: when disease affects one, it affects all your clones. You can protect against that by seed propagation, crossing, etc, but then you have a less predictable and consistent crop, which in the modern market is sometimes frowned upon.

I know most farmers will pick consistency over variety any time of the day because they have to make a living, and most people won't buy greenish tomatoes, yellow or green oranges, white artichokes, etc. People also expect their fruits and veggies to taste as expected, so it's difficult to sell mixed variants.

Note: I should also say I'm from a family of farmers so I'm probably biased towards defending our practices -- in our case we grow citruses, stone fruits, artichokes, aubergines, melons, etc. (not big-agro scale, think more cooperatives in rural Spain), and I do have my personal opinions on traditional techniques vs. modern vs. big-ag, use of pesticides, overstressing the soils, etc. I'm also from an area that has suffered bad droughts and deforestation over generations so I'm also not one to romanticize about traditional farming methods and some traditional attitudes. Take whatever I say with a pinch or more of salt!

My initial comment was just to make the point "Maybe you can't use Asians and their experiences as a rebuttal for some American study because maybe it's an apples to oranges comparison."

I could have said that without mentioning GMO. It's not necessarily hugely pertinent to the point.

But everyone is latching on to that detail and this has gotten enormously whackadoodle.

I stand by my original point. I even stand by everything else I've said here.

But other people reacting like I'm some strident anti GMO nutter for mildly observing that "GMO plants may be fundamentally different from non GMO plants" is not something I have any desire to engage with further.

Exactly. My 3 main concerns with GMO are anything related to pesticides, anything transgenetic, and the privatization of biology thru IP capture.

I'm sorry those risks fall under the rubric of GMO and not "corporatism" and "theft". Blame the GMO rhetoric on big agriculture.

A helpful contrasting example for the apologists:

Wheat with better nutrition and yields: good.

Wheat which requires matching pesticides, herbicides; where seeds are sterile; where seedstocks cannot be shared, reused, resold; where wheat incorporates genetic code from other plants: bad.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2721724/figure/...

So if you have low BMI you improve sperm concentration if you eat soy 2-8 times a week? Less or more than that is worse? Data is not convincing, and it is easy to find studies which don't agree.

Yeah Asia is an interesting one for this. In Japan at least they eat a tonne of fish and seaweed which has a lot omega 3 which is really, really good for sperm so maybe there’s other factors.

Like I’ve said on other comments. When you’re in the situation of having to figure it out, it’s simpler to just blanket cut out anything with any evidence whatsoever. If it improves your chances 1% then it all adds up.

Lard from pasture raised pork is also higher in omega 3. In the USA we switched to a "meat hog" around the 1920-30s for better industrialization. Just a heads up pasture pigs like Large Black hogs or wild boar do have a different flavor but you can buy the lard alone to cook with.

This is where i think science has been failing us. I have a couple similar stories where I have various reactions to one product but not a very similar product from another vendor. When that happens it would be really helpful if there were a research lab/etc where one could show up with both products and basically say, product A does the following to me, while product B doesn't.

The first time I really noticed this was ~15 years ago I was on a spinach salad kick that started when I purchased an organic pre-packaged salad kit (as In I was almost exclusively eating just spinach salad for a couple weeks because I really liked it and my kitchen was being remodeled). Anyway, those kits were quite expensive, so I switched to a cheaper non organic spinach and my own dressing. I started to have some pretty severe intestinal distress over a couple days, and swapped the spinach for a 3rd organic brand and the problem went away. But because the no organic brand was cheaper I bought a couple other bags assuming it was probably just a bad batch and I had gotten hit by a bacterial infection/whatever and it returned.

So I've had similar issues with coffee (gotten ichy all over when I changed brands and couldn't figure it out for a couple months), and a few other products. My Dr describes me as "allergy prone" but its not as simple as I'm allergic to spinach, or coffee. I seem to have a low grade allergy to something that is sometimes present across multiple food sources. I suspect without any proof at this point its a pesticide or herbicide, since I seem to have far fewer reactions if I'm tending to stick with organic leafy vegetables, and away from crops which have traditionally used more industrial farming processes.

If you look at the pesticide/herbicide studies what is abundantly clear in the US, that just like e-coli its hard to predict/track which foods are affected at any given point . The food growing and distribution system is to complex. So while a farmer may be following all the rules, he may be downwind (or whatever) of another farmer growing and spraying a different crop. Then his crop gets mixed into a larger batch and it goes complexly undetected because in low doses many of these products are considered non-harmful.

Someone once told me allergic reaction to soy may actually be allergic reaction to GMO soy, not soy per se.

There may be very different stats from one country to another on how much GMO soy gets used.

Can you link a study that shows GMO soy having different proteins that would cause a specific reaction vs. non gmo? Otherwise it seems like you are hear to just spread anti gmo fud, which really hurts actual discourse around GMOs.

I replied to one person who said they consumed a lot of soy in one situation with zero problem and then reacted really strongly and negatively to soy in another and I suggested a possible explanation, a possible difference between the two soy sources. I did so as food for thought for that one individual and I don't really care what anyone else thinks of the comment.

I can't speak for other Asian countries, but here in Indonesia tofu and tempeh (fermented soybeans) are a lot more common than in Europe.
