Dear lemmy, someone very close to my heart is starting to fall into conspiracy theories. It’s heartbreaking. Among other things, he has now told me that soy beans are not supposed to be consumed by human beings and is convinced that despite the literal centuries of human soy bean cultivation and consumption, we shouldn’t eat it or anything derived from it for this reason (ie tofu, soy sauce, etc…evidence that soy is present in other common foods doesn’t seem to register with him).
I don’t even know where he got this information from and can’t find a single source to back it up (even disingenuously). I’ve tried explaining to him that sure, in its original state it’s not edible, but undergoes processing (LIKE MANY OTHER FOODS) to become edible. And that this has gone on since at least the 11th century, so it’s not like Big Soy is trying to poison the little people.
He’s normally a very reasonable and intelligent person, and I don’t know how to reach him. I thought it might be helpful to show him where these myths have come from with hard data sources to prove it. He seems open to the possibility, so I don’t think he’s a lost cause yet!
Help?
Because it wasn’t obvious that there had been contact with sewer water, if people go out of their way to get water from a pump that tastes “sweet” then they obviously do not understand that there’s sewage in it, as humans universally agree that drinking sewage is disgusting.
It doesn’t take germ theory to figure out that funky water tends to make you sick, and ever since we invented fire and had access to waterproof vessels people would have realized that boiling water made it safe. People just don’t tend to bother with such things when they get comfortable, much like how we now very much know about bacteria and yet people don’t bother washing their hands after taking a dump.
They didn’t know it had anything to do with the water at all, they thought it was evil smells.
The problem is that water is very often contaminated without seeming contaminated. If you drink water out of a random stream in the woods that looks and tastes totally clean you will still very likely get sick, for example. Would people in the past have understood that it was the water from the stream that made them sick? I think they normally would not have made the connection. It’s normal even now when people get ecoli or something from salad, to end up believing the cause was something else before it gets officially tracked down, because what actually happened didn’t match their expectations, they weren’t thinking about salad as a possibility. Our natural disgust for the most obvious signs of disease is woefully inadequate and does not at all translate directly into an accurate understanding of how disease works and why it happens.
