Beware the smell of bitter almonds: Why do many food plants contain cyanide?
July 21, 2010 By Diana Lutz
Could lima beans kill you? Probably not. Lima beans commercially grown in the United States are restricted to two varieties with low cyanide levels.
(PhysOrg.com) -- In murder mysteries, the detective usually diagnoses cyanide poisoning by the scent of bitter almonds wafting from the corpse. The detective knows what many of us might find surprising — that the deadly poison cyanide is naturally present in bitter almonds and many other plants used as food, including apples, peaches, apricots, lima beans, barley, sorghum, flaxseed and bamboo shoots.
There's a reason that cyanide exists in all these plants, and it is — to paraphrase Sherlock Holmes — evolutionary, suggests Kenneth M. Olsen, PhD, an assistant professor of biology in Arts & Sciences at Washington University in St. Louis.
Olsen, who studies white clover, cassava and other plants that produce cyanide, says the plants have an ingenious poison delivery system, one that evolution has designed to discourage herbivores from feasting on them.
Due to proper food processing techniques and strict regulations, cyanide-wielding plants pose little threat to the American food supply. But, in Africa, where cassava root has become a major part of subsistence diets, many poor people suffer from a chronic form of cyanide poisoning known as konzo.
How plants make cyanide
The plant stores the cyanide in an inactive form, typically as a cyanogenic glycoside, which is a sugar molecule with an attached cyanide group (carbon triple-bonded to nitrogen).
The cyanogenic glycoside is stored in one compartment of the plant cell and an enzyme that activates it is stored in another compartment. When an insect or other animal chews the plant and crushes the compartments, the two chemicals mix, and the enzyme cleaves the cyanide from the sugar. It’s a bit like breaking a glow stick to mix the chemicals that make the stick fluoresce.
Olsen describes it as “a cyanide booby-trap.”
Apple seeds contain cyanide (not arsenic as people commonly think) but even if you eat the core, the seeds are likely to pass undigested through your system.
What cyanide does to poison you (or the relevant herbivore) is equally ingenious. It prevents cells from using oxygen by binding in its place to the biomachinery that converts food to energy. This causes what is essentially a molecular form of asphyxiation.And the molecular pathway it blocks is so ancient and universal, cyanide is effective against most life forms, from insects to people.
Why so many food plants contain cyanide
Why do so many food plants contain cyanide? There are two answers, Olsen says. Cyanide acts as a primitive pesticide that discourages insects that feed on plants. The very earliest farmers, selecting plants to bring into cultivation, might have found these “clean” plants particularly attractive. By selecting plants that hadn’t been chewed up by insects, they may have inadvertently selected ones that were cyanogenic.
But the second and perhaps more important reason is that as plant toxins go, cyanide is a manageable one. The cyanide in apples and peaches, for example, is in their seeds and pits, which are usually discarded.
In addition, Olsen says, even if an edible plant part contains the poison, it is easy to get rid of. All you have to do is crush the plant, then wash the mash. Crushing releases the water-soluble cyanide, which is carried off in the water.
Disabling the genes that code for cyanide production is also straightforward. It took only one genetic mutation, for example, to turn the toxic bitter almond to the benign sweet almond.
“You’ll notice that the oak hasn’t been domesticated,” says Olsen, “and this may be because the poison in that case is not a single compound but rather a broad class of compounds (the tannins) whose production is controlled by many different genes.”
“Many mutations would be required to generate a low-tannin oak. Also tannins are not sequestered in one part of the plant, such as the leaves, but instead are found throughout the plant, so it isn’t possible just to remove the offending part.”
“Squirrels have evolved digestive systems that can handle the oak tannins," Olsen says. "But tannins definitely discourage acorn consumption by people.”
The problem with cassava
One plant that can deliver problematic amounts of cyanide is cassava, also called manioc, tapioca or yuca.
Olsen, who has studied the domestication of cassava, says that it is native to South America and was imported to Africa by the Portuguese only 300 or 400 years ago. It remained a minor crop until about 100 years ago, becoming important only when soils became too degraded to grow traditional African crops.
The skins of unprocessed cassava roots actually contain sulfur-containing proteins that would help people who eat cassava metabolize cyanide in the root, but the skins are usually removed when the roots are prepared.
There are sweet as well as bitter strains of cassava, but farmers often prefer the bitter, high-cyanide ones, because they discourage insects (and thieves — who avoid the roots that require laborious processing).People have the ability to detoxify some cyanide if they ingest it slowly and over a long period of time, and if they have sufficient protein in their diet, particularly sulfur-containing amino acids.
Those who suffer from konzo are often subsisting on little other than cassava and may also not be processing the root properly, since detoxification requires an abundant water supply.
Tacked to Olsen’s office wall is a woven palm-fiber basket that looks like a giant Chinese finger trap. The purpose of this intriguing South American implement, called a tipiti, is to wring the cyanide out of grated cassava. It is also a reminder of the ingeniousness of plants, which are not the patsies animals often think they are, but instead experts in chemical warfare.

Evolution is a natural process. It has no goals. Not even survival. It is simply the process whereby mutations are selected OUT by lack of reproduction. Thus those that don't survive fail to reproduce.
Mutation supplies the raw material of evolution. Selection is the result of not reproducing thus removing the mutations that are harmful. There is no intent nor design simply the inevitable result of changes that didn't help but hurt. Changes that help survive and reproduce.
There is no intelligence involved in Evolution nor design. Just survival in an environment that destroys changes that fit.

That would depend on your concept of god. Jehovah as shown in Genesis simply does not exist as the world we live in is not compatible with the world of Genesis. Vaguer concepts of a god are often compatible with the Universe, except for the miracles and that is the belief part. Rational thinking is not compatible with irrational beliefs. Believing in miracles is, at best, on the very edge of rationality.
Twenty-five percent of Americans take the Bible literally and an even larger percentage believe in the Flood as an actual event and not just a myth. Not as a legend of an ancient local flood but as a world wide flood.

I have a vague recollection of that. He died of cancer. Often the clinics would ship dying victims off to other clinics so they could continue to claim that none of their patients had died. They died alright just in a different clinic.
The thing about laetrile is that it sounds right. Just like real drugs are supposed to work only with better targeting. Catch is that it wasn't tested until long after were claiming it was a cure. It failed the tests and people still believed it worked.

Maybe in the old days people ate the core of apples that contained the seeds that contained laetrile that attacked cancer cells when the cancer cells were small, in limited quantities and vulnerable to laetrile.
I read a study in the past that stated that laetrile works in preventing cancer when taken in small quantities over a long period of time.
The problem is that most people wait until they have cancer before using laetrile.
I have also heard that the cyanide found in laetrile is not released until it is exposed to the cancer cells at which point the cyanide is released. The problem with laetrile is that it is very dangerous and toxic when taken in large amounts.

"If someone already has cancer, then it is too late to be treated with laetrile."
This is only the latest falsehood in a long string of baseless claims made about laetrile. Oncologist Benjamin Wilson notes:
"Claims for Laetrile effectiveness have also shifted. At first it was claimed to cure cancer. Later it was claimed to "control" cancer. When the "vitamin" theory was developed, it was touted as a cancer preventive. It has also been claimed to be effective in relieving pain associated with cancer and in facilitating treatment with chemotherapy."
Check out the checkered past of this "cure" by Dr. Wilson (The Rise and Fall of Laetrile): http://www.quackw...ile.html .

Laetrile is derived from the naturally occurring glycoside amygdalin, found in apricots, black cherries, and the seed of the bitter almond tree. Apples do not contain amygdalin.
I find it interesting that laetrile's promoter Krebs, Jr. was unable to come up with a consistent formulation of the drug that could be used in laboratory testing. Widely inconsistent versions of the drug offered as 'laetrile' are still with us today.

You're confused. Nature can indeed design, and it requires no intelligence within the designer.
A group of 50 plants, same species, give rise to another 100 plants (Generation 1). These plants all have 1 mutation. The majority of these mutations do nothing substantive and are neutral. 10% are harmful and kill the plant before gestation, 10% are beneficial and engender distaste when eaten. Animals eat 50% of the total, avoiding the distasteful ones.
So after the first generation you now have 90 plants, 50 of which are eaten, 30 of which are not and carry no gene, 10 carry the gene.
1:2 reproduction, 80 plants. 10% die, (72 left) 50% eaten, (36 left 20 of which carry the gene).

You now, through no intellect, have a designed genetic response to predation, the primary selective pressure. That is evolution, that is design, that doesn't require a god, that is what we've observed in nature, and look at how quickly it happened, 3 short generations.

Do you have any published large-scale studies you can cite? Ironically, laetril/amygdalin is one of the best studied compounds in the treatment of cancer, due in part to the claims made in the 50s, 60s and 70s. But if you want to spend your wages on an unproven 'cancer prevention' treatment, just make sure you know what your buying. Same as Ectsasy or LSD, assayed samples of 'laetrile' have been found to vary widely in their content.

Evolution does NOT design anything. Period.
It is a process that shapes life. There is no plan and no design. But it is often very hard to avoid anthropocentric language.No it isn’t and if the definition is correct than it too is a very poor choice in discussing evolution. There is no more intent then there is intent when two hydrogen atoms combine with an oxygen atom to form water and release kinetic energy.

People keep on ranting about it being a cure, which it is not.
I do not sell or take those drugs, but I do believe a natural approach can be beneficial in many cases, but not as a cure.
However, if someone has a urinary tract infection, most doctors will prescribe antibiotics such as ciprofloxacin, instead of using a natural approach.
As a matter of fact, most doctors are unaware that cranberries or cranberry juice will clear up the infection more effectively than Cipro without the side effects.
I think it is reasonable to consider laetrile as a preventive, just like one would consider orange juice, cooked tomatoes, dark red wine, dark chocolate, broccoli, etc., etc. as preventatives.
So if you people would like to continue this conversation with me, then you will need to stop talking about prescription drugs.

It has nothing to do with the fact that laetrile is natural. It has to do with the fact that properly conducted studies have not conclusively shown that it does anything to cure or prevent cancer.

Skeptic Heretic: You can check around on the Internet about the cranberry treatment. From personal experience I can say it works. Other people have tried it and it worked for them. If it does not work, then a person may need surgery.
A prescription drug made from cranberries and then given a fancy name may be what is needed for doctors to start prescribing it.

I should add that cranberries can be toxic when excessive amounts are consumed.
A lot of people who find cranberries successful in treating a urinary tract infection may be likely to start over consuming the product, which is a bad idea.
Cranberries are very acidic, so problems could arise from consuming too much.

To be fair everything is toxic when consumed in excess.

Anyone familiar with the standards of evidence know that uncontrolled personal observation is about the lowest form of evidence possible, only exceeded by relayed uncontrolled personal observation.
Link a study for us, or if you have the ability to take good notes under controlled settings, run a study and publish it.

Snark by EthelredIF it worked it would be reasonable, since it doesn't, then it isn't. All those others you mention are primarily anti-oxidants. Laetril is a untargeted cyanide carrier based on a chemical which evolved to kill insects. Cyanide is NOT an anti-oxidant.

I once cured a throat infection with Listerine. But if things had not improved I would have gone to a doctor, who probably would have prescribed an anti-biotic. Those things work. Then again I haven't gone to a doctor since oh around 1974.
I don't want to think about how one applies cranberry juice to the urinary tract. That is right up there with self dentistry.
Even snarkier question REDACTED.

I had a UTI once. I smoked a lot of tobacco and marijuana and it got better.
I'm not advocating marijuana or tobacco as a UTI cure, because they're not, and my anecdotal experience isn't proof. If I were braindead and didn't recognize that I had an immune system well honed to defeating infections, I may think that tobacco and marijuana fixed the problem.

I like the idea behind the laetrile story in how they supposedly attack individual cancerous cells.
Research in nano technology will most likely provide a more accurate way of doing the job than using laetrile.
As for the score keepers, your math does not add up.
I provided a source in which laetrile was touted. Maybe the source was not to your liking, but it was a source.
So as far as I am concerned, that is 1 for 1.
It is interesting how those articles about cranberry juice help support my claims. I never said it worked for everyone, only that it has worked for me and others that I have talked to.
My math now shows 2 for 2.

Several times before the surgery I used cranberry juice and it stopped the pain. Cipro was too toxic for me and I had to discontinue using it. Then I did some research or talked to someone, and tried cranberry juice. I got rid of the pain and the problems went away.
But what I think was going on was there was something causing the pain that went away after the surgery.
Cranberries as a cure, maybe not. As a treatment, yes for me.

I have heard that cancer cells attract laetrile and once absorbed by the cell the laetrile releases the cyanide.
That is the story I read about. I do not endorse laetrile, but the idea behind laetrile and how it is attracted by cancer cells I find very compelling.
Nanotech is where the cure for cancer will most likely come from. Laetrile is the first thing I have heard of that at least tries to put up a fight against cancer. If it works or not, it is still a compelling story, a place to start from, a stepping stone to better things to come.
Those are the realities.

This is what I am interested in. When you say NOT targeted, are you talking about laetrile or nanotechnology attacking cancer cells?
The ideal solution would be for nanotech to be able to target cancer cells individually in theory like laetrile is said to work.

Second I am positive that a quack nostrum that has been proven ineffective in EVERY test and proven not to act as claimed is positively CRAP.Yes, you made that unsupported claim before. I linked to stuff that showed the claim was bogus.That is a strange claim as you have done nothing here but endorse it.Only problem is that it is disproven.Certainly for some cancers. Except that there won't be A cure for cancer as there are MANY types of cancer. And some already have fairly effective cures for many people.

There are two types of therapy. One is peptide receptor radionuclide therapy, where a radioactive substance (yttrium 90 or lutetium 177) is coupled to certain receptors of the target tissue. (See wiki page "GEP-NET".)
The second type works without radioactive nuclides by - AFAIK - blocking hormone production in GEP-NET tissue. (There seems to be no wiki page on that subject.)

With cancer deaths at a rate of 22.8% in the U.S. during the year of 2002, only second to heart disease, I think there is a lot of money to be made by investors in the short future.
