Scary Science That Humans Have Foolishly Embraced

250 BCE Lead, Lead Wine

Ancient Romans use lead in everything from paint to dishware to plumbing, despite warnings from Caesar's engineers.

Actually, Romans love the stuff so much that they add lead acetate to wine as a sweetener.

Lead poisoning runs rampant, leading future historians to speculate that lead-induced insanity caused the fall of Rome. (Image: Dionysus as baby by Guido Reni)

50 CE Listen To Your Elder

Roman historian Pliny the Elder notes that asbestos in clothing "affords protection against all spells, especially those of the Magi." If that's not handy enough, the Romans also discover that asbestos is a strong building material, and that it can make tablecloths flame retardant. (Simply burn off the food to clean them!)

Curiously, Pliny also warns against purchasing slaves who've worked in asbestos quarries. He writes, "They die young."

1527 CE Opium for the Masses

Physician and toxicologist Philippus Paracelsus prescribes opium as a painkiller throughout Europe. Using his marketing genius, he also re-brands the drug under the more wholesome name "laudanum."

During the next 300 years, the drug becomes as commonplace as Advil, and it's prescribed for everything from colds to diarrhea to insomnia.

Poets and novelists, including Elizabeth Barrett Browning and Charles Dickens, even take laudanum to cure writer's block. Mary Todd Lincoln combines the drug with camphor in an effort to commit suicide, but she's foiled by a suspicious pharmacist who plies her with sugar pills instead. (Photo: NLM Visible Proofs)

1850 CE And Speaking of Camphor ...

In the mid-1800s, swallowing camphor is thought to cure hysteria, cholera, and gout. Later, however, medics wise up to the toxic nature of the gummy compound, and it's relegated to things like fireworks and embalming fluid.

But camphor hasn't totally retired from its career in medicine. It's an active ingredient in Vicks VapoRub, anti-itch creams, and several other products with warning labels that read, "If swallowed, contact a Poison Control Center immediately."

1898 CE Heroin for Everyone!

Got a nagging cough? Some heroin will fix you right up. At least, that's what mothers believe in 1898, when they start buying Bayer Heroin for their sick kids.

Soon approved by the American Medical Association, the drug is marketed as a non-addictive morphine substitute - which is wrong on many levels. Not only is heroin extremely addictive, but the body also metabolizes it into morphine.

When reports of extreme addiction become known, Bayer acknowledges its blunder and stops making the medicine in 1913. But for the next decade, heroin lozenges, heroin elixirs, and heroin tablets continue to dominate the market.

1920 CE Video Killed the Radium Star

Is there anything radium can't do? In the 1920s and early 1930s, companies tout it as a cure-all and put the radioactive element in toothpaste, ear plugs, soap, suppositories, and even contraceptives.

One of the biggest sellers is a radium-laced water called Radithor. Steel magnate Eben Byers drink approximately 1,400 bottles of the stuff over the course of several years, believing that it is the key to longevity.

After undergoing operations to remove parts of his mouth and jaw, he dies in 1932 as the rest of his bones disintegrate. The drink's popularity plummets after it's implicated in his death. (Photo: Oak Ridge Associated Universities)

1971 CE Breakfast of Champions

Executive Robert Loibl decides to prove that his company's pesticide, DDT, is completely harmless.

For three months, he and his wife take a concentrated dose of the poison every morning before breakfast. The Loibls report no negative side effects and claim to feel more energized after their "treatments."

Studies later confirm that DDT is not acutely toxic, but rather, that it induces certain cancers and neurological disorders that take years to develop. (Photo:

"Wow"... yeah, sorry, but your response is as rude as it is wrong. The thing about the Asian soy diet is that it had a couple millenia of development (consider the fermented forms, which render the proteins more digestible), it was never a "health food" so much as a "poor person's temporary protein supplement" (soy burgers are a Western mistake)... And that sexist tradition where the men in the family got the best food (ie. real meat)? Sure helped limit the impact of the female hormones on them, don't you think?
Still, though, a look at Asian society today will show some of the long-term damage caused by those hormones (I can't tell you how many male students I have who look--and act--like girls, for example).
Like EU Copyright said, Western farmers and food producers love soy--but the soy they sell is NOT what we eat over here (in Asia).

EU Copyright, there is no response more appropriate to your post other than, wow, you are a complete moron. Ever heard of edamame? It's been eaten for millennia by Chinese, Japanese, Koreans, etc. Yah, it's raw soy... idiot.

Reminds me of biology class where we got to see a package of 1800's "diet pills" that were actually live tapeworm eggs. Thats one way to drop some pounds quickly and easily!

SWING, you are moron just trying to seem smart over the internet. think before you speak. most perscription medicines and many elements have a latin or ancient greek name. just because they are dead languages does not mean shit... except to you i guess

Another common 'food' that will soon be proved too dangerous to eat is Soy and soy-based products. Deadly and dangerous stuff.

Farmers love selling the stuff because it is easy to grow and will grow anywhere. Soy cannot be eaten raw, it needs extensive processing before it can be eaten. Even then, it is high in isoflavones (like female hormones) and is seriously damaging to the thyroid.

Feeding a child soy-based baby formula is like giving them 5 birth control pills per day. Male babies fed soy milk may never develop an interest in girls.
