True or False: Nutrition Edition
From the "don't believe everything you hear" department (courtesy of The Guardian):
Folk "wisdom" usually isn't wisdom, but mythology. People have always had a problem confusing correlation with causation.
Sometimes, though, like a sightless person throwing darts randomly and hitting a bullseye, it turns out to be right—at least provisionally.
How do you tell the difference? Science, of course.
I won't copy all of them here; there are quite a few. Just hitting some highlights that I wanted to comment on.
Chicken soup helps cure colds and flu
Works best if prepared by a Jewish mother.
Okay, no, that's a joke. But I'm pretty sure the canned kind is going to be inferior to the homemade variety. I'm wary of the word "cure" in the title; however, this falls into the "can't hurt and might help" category. Unless you're vegan, in which case, good luck.
Anyway, I've banged on about chicken soup in here before. The short version is, if it makes you feel better, and you like it, great.
Chocolate causes acne
This one's labeled "false." As with much of "nutrition science," the jury's still out. 
An apple a day keeps the doctor away
Also labeled "false," but only on a technicality: you're going to get sick eventually, no matter what you do or don't do. But, as the article notes, it's not going to hurt you to eat a damn apple. And it's admittedly a catchy rhyme.
Going out with wet hair gives you a cold
"False." Duh. Colds are caused by viruses. Viruses that you pick up from *shudder* people.
Carrots help you to see in the dark
The article points to "true," but I have to say, not to the extent that mythology would indicate. This nonsense started, if I remember correctly, in England during WWII, when, not wanting "zee Germans" to know about the Allies' sophisticated (for the time) radar, they attributed early warning of aerial attacks to people eating carrots and therefore seeing the impending threat better in the dark.
But again, as with apples, it's not like eating a few carrots is going to hurt.
Cracking your knuckles will give you arthritis
This one's false, and I've known that for some time, but goddamn, it's annoying. So if you use it to scare kids into not cracking their knuckles, I can understand that.
I crack my knuckles all the time.
It takes up to seven years to digest swallowed chewing gum
Another false one intended to scare children straight.
Garlic under your pillow aids sleep
Labeled "false," but I'd call it true, if you're frightened of vampires; clearly, you're going to sleep easier if you know you're protected. It also keeps other people away because of the smell, so you get a better night's sleep.
Still, when it comes to garlic, I'm too busy eating it to put it under my pillow.
Urine relieves jellyfish stings
I'm including this one in my commentary because I'm still hearing this nonsense sometimes. I suspect it got started by someone with a pee fetish, which is way more common than I ever realized.
Oh, yeah, and it's false.
Cheese gives you bad dreams
I remember the first time I heard of this one. It was in Dickens' A Christmas Carol, as Scrooge attributed his nocturnal visitations to possibly having eaten cheese.
As the article notes, dairy products might actually help with sleep. Again, good luck, vegans.
Probiotics support your gut health
This is the last one on the list, and it doesn't surprise me in the yeast—er, I mean, least—that it's not entirely true. The magical benefits of probiotics are mostly marketing gimmicks.
Big surprise. |
