Reminds me of the theory that wheat domesticated humans.

driving down the road I was inspired to taste some fresh wheat grains in a field: tasted a lot like flour. what is that "thing"? an attractive tasty flour nodule? the energy yolk to the seed's egg?
I picture your ancestors impulsively tasting mushrooms, and figuring out which ones were not poisonous enough to kill them. Thank you for your lineage!

In Mexico, our ancestors cultivated corn despite not knowing fungicides to prevent mycotoxin contamination. Somehow they discovered nixtamalization, which is boiling corn in an alkaline solution that destroys mycotoxins and improves nutritional value. Guess they really loved corn.

https://en.wikipedia.org/wiki/Nixtamalization

If you have a few 100 people in an area literally spending their waking hours worrying about having enough food. Areas without enough of the right nutrients are pretty common. People are pretty good at figuring out what makes them feel better/healthier.

Some places are iron poor, some even resort to eating dirt, especially when pregnant when you need more iron. Some areas are salt poor and animals will go to extreme measures to get to salt. Some areas have poor bioavailability and require crushing, special cooking, soaking, or a narrow range of acidity to be available, which of course becomes the norm for cooking in those areas. Some even become religious standards, things like fish on fridays or avoiding pork (before trichinosis was controlled).

>Somehow they discovered nixtamalization, which is boiling corn in an alkaline solution that destroys mycotoxins and improves nutritional value.

that one always amazes me. How did they figure it out? it's not exactly intuitive, especially when they wouldn't have known about the chemistry underneath.

It would probably take weeks or months to notice if doing A instead of B was making people sick or not

It might not be that the process was discovered so much as the method of cooking pot production happened to suit the food being cooked.

In particular, lots of civilizations learned to strengthen the basic clay pot by the addition of lime-y things, eg burnt mussel shells. If all your pots are made in this manner then you dont so much discover nixtamalization as experience it only by its absence when you meet settlers that have pellagra and dont use your style of pot.

See [0] for a technical write up on this and many other pot themes.

And also the tribes which used other pots didn’t thrive as much.
Maybe some people with sensitive stomachs are able to detect things like this quicker than others. Further, maybe the gene for a sensitive stomach confers a survival advantage not just to the individual, but to relatives of the individual (who can ‘free ride’ on their relative’s discerning stomach).
What fun to be the village poison tester because you’ve got the most sensitive stomach.
boiling corn in limestone pots makes it taste better
> How did they figure it out?

My guess: boiling water purifies it and makes it safe to consume... how about put things in boiling water to see if it makes them safer?

> your ancestors impulsively tasting mushrooms

There are other animals humans can observe instead of impulsively risking their lives.

Sure, there _are_, but also don't underestimate humans...

It's been nine days, and I've been thinking sporadically about your comment. The two links you provided are great to make your point. Specially the second.

> She remarks that the older man “should be dead” and the younger one “should be alive.”

Great storytelling.

I was in Cape Cod for a wedding late last year with some friends, and came across what we later learned was a Yew. Some of us had popped into an ice cream shop, and one of the members of my party apparently decided to eat a sweet berry while they waited.

When we came out, we were initially incredulous but they clarified that the flesh of the berry was sweet, but the seed was disgustingly bitter. Which prompted the rest of us to quickly do some research on what this plant was. The mood was initially somewhat light-hearted, however articles with titles like “Why is the Yew Berry sometimes called the Death Berry?” had us on the phone with poison control pretty quickly.

Poison control was very professional, and once they confirmed that it was indeed a Yew Berry that had been ingested, things got pretty serious. Apparently even small doses can quickly cause irreversible heart failure, with death the earliest “symptom” in some cases.

My friend didn’t die— just experienced some terror and gastric distress— the latter likely exacerbated by the terror). No drugs or alcohol or involved, just an impulsive decision, and a sobering reminder about the fragility of life.

One of the other replies in this thread mentions mushrooms. Which reminds of the aphorism: _There are old mushroom foragers, and bold mushroom foragers, but there are no old AND bold mushroom foragers._

Oh wow that was a journey. As soon as I saw "yew" I started internally screaming.

The route that my kids walk to school took us underneath a large yew tree, and the road underneath is often covered in hundreds of delicious-looking pink berries. Since they were tiny they have had to know all about how yew berries look lovely but even one can kill you. What I didn't ever tell them is how apparently the flesh is actually not toxic and is tasty, and it's the seed that will kill you.

The aril (the red flesh of the “berry” surrounding the seed) is tasty, and not toxic. But the leaves, stems, roots, and seeds are poisonous. Our elementary school has evergreen yew bushes growing around it and I taught my children not to eat the seeds. A fellow parent advised use not to eat them because other children might not be so careful.
Are yew rare where you are? Here in Ireland (and also in Britain), they're traditionally found in churchyards (where grazing livestock cannot get at them) and are well known to be poisonous. (Agatha Christie used yew as a poison in one of her novels.)
I read this and thought; I sure hope so if I’ve made it this far in life not knowing. I believe someone’s rectangle plant-identified this particular one as European Yew (Taxus baccata). None of us had encountered it before and this particular plants arils (thanks drjason) were quite strikingly pink.

Apparently, there are others in North America, but mostly not in the Southwest. I lived in the Pacific Northwest about a decade ago which also has a yew (Taxus brevifolia) but I don’t recall if I ever saw the berries.

That said, most folks I know were raised with a baseline of “don’t eat random berries you don’t recognize.”

They're common in landscaping throughout the US. We had some in our front yard, but us kids knew better than to eat random berries. It's painful for me to think that there are people out there without the common sense not to eat random plants they don't recognize.

Folks visiting the desert and distractedly running straight into octillos is just good entertainment. There's not much on the east coast that prepares you for a random shrub to be so hostile. Poisonous berries though, they're everywhere. I'm surprised your fellows made it to adulthood without basic suburban survival skills.

> It's painful for me to think that there are people out there without the common sense not to eat random plants they don't recognize.

I think it's understandable. I live in a city suburb and the foliage around me is pretty much all non-toxic.

I was raised in a rural community and went camping often so we had the lessons of "don't eat random shit, you'll die" drummed into us.

The berries (but not the seeds!) are apparently edible, and I have myself eaten one without noticing any ill effect. IIRC it was indeed the berries that were used in the Agatha Christie novel, so apparently a mistake.
This is an example that mushrooms unfairly get a bad rap - there are much nastier things in the plant kingdom. Some of them you don't even have to eat to get seriously hurt by, and they're not even that rare (e.g. giant hogweed)
Yikes - I love foraging, but I am extremely conservative about what I eat. This makes me thankful I'm not a bold forager.

My friend has a running joke calling Yew poison berries, but I never looked up the effects before. Great that you called poison control.

while it's incredibly coincidental that you replied to me to say this

>I was in Cape Cod

it give me the chance to tell you, "we say on Cape Cod". There are a number of towns on Cape Cod that you could be in.

Nightshade (atropa belladonna) is another one to watch out for.
I'd add hemlock in there in too. Both are plants you'll see in parks in town. A toddler died here a few years ago because his parent allowed him to play in the big plants with the pretty white flowers. They don't look dangerous and don't have to be eaten to be deadly. Breathing too much pollen is enough, especially for a child.

I'm pretty confident with berries as I've got plenty of experience, but I don't mess with wild carrot or even elderberry as I don't feel I have the knowledge at this point to make it worth the risk. There are just too many lookalikes.

And, other nightshades such as tomatoes, bell peppers, and goji berries contain lectins.

Fun fact: The danger in eating raw cookie-dough isn't primarily from fresh eggs (though they can have problems too) but rather from the raw flour, which before cooking may have a bunch of bacterial nastiness in it.

Choking on the mixture is the main danger.
I wonder if that has a higher death rate than driving to the store to buy it?
I feel like dividing the outcomes into just two buckets of "direct cause of permanent death" versus "everything else" isn't the ideal way to approach routine decisions about what to eat. :p

("This cardboard is unlikely to kill me, sooooo...")

> ("This cardboard is unlikely to kill me, sooooo...")

Yeah, but it ain't much fun to eat, either?

Both probably higher than taking the subway to work.
Raw flour is generally not pasteurized, it's true, but most cookie dough mixes are.

The eggs are a far more likely vector for illness unless you're making the cookies yourself from scratch.

You can easily pasteurize both eggs* and flour at home, and make Cookie Dough That Won't Kill You (Nearly As Quickly)

* with the right equipment

I assume "the right equipment" is "an oven", and "Cookie Dough That Won't Kill You" is usually referred to as just "cookies"? ;-)
You can microwave flour to make it safe without actually cooking it.

Don't know about eggs, but some recipe sites claim it works for them too.

You can pasteurise eggs with a basic sous vide setup. Take any of those home sous vide circulators, set it to 140 F, and once it's up to temperature put the eggs in for 4 minutes...
> unless you're making the cookies yourself from scratch

This isn't the default assumption?

> most cookie dough mixes are

At least where I live, only a minority are advertised as "ready to eat". It's more common to see the opposite, an explicit warning that it must be cooked.

That just puts a frisson of risk into your decision to eat the raw dough, which wasn’t a good idea to begin with.
Basically, yes. Though wheat didn’t look like that initially. We’ve cultivated it to become like that over thousands of years.

Same for corn (maize). There is no naturally occurring plant that looks like what we’ve turned it into.

Wild potatoes look pretty close to some domesticated potatoes I had.

Also I had lots of wild berries (of various species) in forests, and they look pretty much like the berries you can find in a garden. (Though probably not like the berries you can get in a supermarket?)

Wild grass also looks pretty much like some of the domesticated variety. (Well, some varieties do.)

My understanding is that most berries weren’t farmed until recently because they couldn’t be domesticated like other plants, rather they were typically foraged. I remember reading that initially wild blueberry bushes were simply dug up and replanted. Not certain of the veracity of this, however.

Wheat still generally looks like wild grasses, but like maize its seeds are much larger than you’ll find on wild grasses.

Wild corn relatives, however, just look like most other grass.
Yes. I agree that most domesticated plants look rather different from their wild ancestors. Just not all.
It's called endosperm. A bunch of starch that nourishes the embryo when the seed germinates.
Speaking of sperm, it reminds me of that funny theory about choanoflagellates: https://news.ycombinator.com/item?id=38865865
thank you! the only one who answered my legit question, if only I could upvote you more
Well wheat co-evolved such that seeds stayed attached after being ripe. Without humans resowing them, it would have been impossible.
