If you’ve spent your fair share of time on the Internet, you’ll have come across many oft-repeated health “facts” that are anything but. From the bogus five-second rule for dropped food to the sugar high, many of these myths are now thoroughly debunked. Because of them, we’re all now skeptical of anything we can’t immediately verify with online search, which is honestly how it should be.

Some of those myths, however, have more truth to them than you might think, as some recent studies have discovered. These are the health myths we tell other people about to sound cool, though if we took some time to look into them, we’d realize that they aren’t actually myths at all.

1. Carrots Do Improve Your Eyesight

It has been a while since the “carrots are good for the eyes” myth was debunked, as anyone who has been online anytime in the last ten years would know. We now know that it was all because of a false campaign by the British Ministry of Information back in World War II, which purposefully propagated the myth across German-held territory to hide their recently developed radar technology.

Now, we’re not saying that the Brits didn’t do that—as they absolutely did—but if that made you completely give up on carrots for being utterly useless, it’s time to reconsider. The popularly held association between good eyesight and carrots may have been based on a lie, but that doesn’t automatically mean it’s false.

Carrots contain many compounds that do improve the health of your eyes, including beta-carotene. It helps the body make Vitamin A, which helps our eyes to convert light into signals understood by the brain. Vitamin A is directly responsible for our ability to see in low light, and deficiency in it can lead to a degeneration of the cornea, which may even cause permanent blindness.

2. Eating Just Before Sleeping Does Give You Nightmares

“Eating a late meal can give you nightmares” sounds like inaccurate advice from that one guy we all know who recently got into fitness and can’t stop talking about it. The timing of the dinner should have no effects on dreams, as dreams aren’t influenced by our diet in any way. It’s something most of us won’t even look up because of how stupid it sounds, though if we did, we’d find that it’s actually pretty good health advice.

Many studies have found a link between eating late and bad dreams, though we don’t understand the exact mechanisms behind why that is. It might be due to our metabolism being overly active when we go to sleep immediately after dinner, which would make the brain more restless and result in increased activity. It’s not just when you eat but also what you eat. Some food items are especially good at inducing nightmares, like dairy and spicy foods… Show More
