There’s something about health and nutrition folk wisdom that’s resistant to truth.
Common health “facts” include the ideas that MSG will construct you sick, that a juice detox is just what you need after a few weeks of indulging, and that sports liquors like Gatorade are wholly penalty since you need the electrolytes.
None of these things are true. They, like many other folk sayings and tips, fall into the category of health myths that are totally or at the least mostly incorrect.
Here’s the truth behind some of those health assertions you’ve heard all your life, but might not hold water at all.
1. MSG in Chinese food will construct you sick .
The myth that MSG is bad for you comes from a letter a medical doctor wrote to the New England Journal of Medicine in 1968, where he coined the term “Chinese restaurant syndrome” to describe a variety of symptoms including numbness and general weakness.
But though medical doctors blamed these seems on monosodium glutamate, MSG, the research doesn’t back it up. The scientific consensus according the American Chemical Society is that “MSG can temporarily affect a select few when eaten in huge quantities on an empty stomach, but it’s perfectly safe for the great majority of people.”
And this attains sense MSG is nothing more than a common amino acid with a sodium atom added. The placebo influence is more than strong enough to account for its negative effects sometimes associated with MSG.
2. Coffee stunts your growth .
There isn’t a whole lot of proof on this, but most research receives no correlation between caffeine intake and bone growth in children.
In adults, researchers have seen that increased caffeine intake can very slightly limit calcium absorption, but the impact is so small that a tablespoon of milk will more than adequately offset the effects of a cup of coffee.
Interestingly, advertising seems to be largely responsible for this myth. A breakfast cereal manufacturer named C.W. Post was trying to market a morning beverage called “Postum” as an alternative to coffee, so he ran ads on the “evils” of Americans’ favorite hot beverage, calling it a “nerve poison” that should never be served to children.
3. Bundle up or youll catch a cold .
Being physically cold isn’t what gets you sick; exposure to a cold virus does. There’s no evidence that going outside with wet hair when it’s freezing will construct you sick by itself furnished you avoid hypothermia.
But there are some scientifically sound explanations for why people catch more colds in wintertime. Because we spend more time in close quarters indoors, it is more likely that we’ll cross tracks with a cold-causing virus spread from another person in the winter. And for several reasons, we may have a harder period fighting off cold and flu virus particles in winter.
But being cold itself isn’t what attains sick, and some “re saying that” cold exposure can actually improve your health.
4. The chemical tryptophan in turkey attains you sleepy .
Who doesn’t love the post-Thanksgiving nap? We frequently consider those sleeps inevitable, since turkey contains tryptophan, an amino acid that is a component of some of the brain substances that help you relax.
But plenty of foods contain tryptophan. Cheddar cheese has even more than turkey and cheddar is never pointed out as a sleep inducing meat. Experts say that instead, the carbs, booze, and general size of the Turkey-day feast are the cause of those delicious holiday siestas.
5. Taking your vitamins will retain you healthy .
Vitamins sound like a great mind. One pill that can provide you everything you need to be healthy!
If only they operated. After decades of research on vitamins, most evaluations don’t find any justification for our multivitamin habit, and in some cases, vitamins have actually been associated with high risk of various types of cancers. Malnourished people might benefit from some supplements, but most of us should just get our vitamins naturally from food.
6. Beer before alcohol, never sicker; liquor before brew, youre in the clear .
We’re all heard it: “beer before alcohol, never sicker; liquor before brew, you’re in the clear.”
But while it’s very true that overdoing it with liquor might leave you praying to the porcelain deities, there’s no need to place the blamed on the order you devour the liquors in booze is booze, and too much of it will make anyone feel sick.
However, there are some strange behaviors this piece of advice can make sense. People who switch from brew to mixed drinks( with senses and judgment already dulled) may be less likely likely to monitor their booze intake and thus booze more.
And some research shows that your torso metabolizes mixed drinks faster than higher-concentration booze( a shot of whiskey, mention ). So adding alcohol to a stomach-full of brew could, in theory, create a sort of mixed drink that would metabolize faster than one or the other on its own.
We’ll call this one partly true, but chalk up the “never sicker” proportion mostly to bad decision making.
7. You lose 90% of your body heat through your brain .
Not necessarily. You lose body heat through anything uncovered, according to Dr. Aaron E. Carroll and Dr. Rachel C. Vreeman, writers of “Don’t Swallow Your Gum !: Myths, Half-Truths, and Outright Lies About Your Torso and Health.”
Your head is not special in that way it’s merely more likely to be exposed.
“Most of the time when we’re outside in the cold, we’re clothed, ” Richard Ingebretsen, MD, PhD, told WebMD Magazine. “If you don’t have a hat on, you lose heat through your brain, just as you would lose heat through your legs if you were wearing shorts.”
8. Wait an hour after feeing to swimming or you’ll drown .
Some parents say no swimming for 30 minutes after eating, some mention an hour, but many of us may remember waiting out the clock before returning to the pool or beach. The theory behind this seems to be that digesting meat will draw blood to your stomach, means that less blood is available for your muscles, building them more likely to cramp.
But there’s no proof to subsistence this claim. In fact, many sources say there are no documented cases of anyone ever submerge because they’ve had a ache related to swimming with a full stomach.
Cramps do happen frequently when swimming, but they aren’t caused by what’s in your stomach. If you do get one, the best policy is to float for a minute and let it pass.
9. It takes 7 years for gum to digest if you swallow it .
When it got out that Trump press secretary Sean Spicer chews and swallows two and a half packs of chewing gum by noon every day, many people had the same topic: Couldn’t that maybe do some damage?
Probably not. Gum is mostly indigestible, meaning that it usually passes through your intestines and exits the other side, like the majority of members of what your torso doesn’t need and can’t digest.
“On rare occasions, large quantities of swallowed gum be included with constipation have blocked intestines in children, ” Dr. Michael Picco of the Mayo Clinic writes. Still, he mentions swallowing gum generally isn’t harmful.
10. When you’re drunk on gin, you get mean .
There are plenty of alcohol-related myths out there, and the idea that different boozes have different consequences on you is a big one. Some people claim wine attains them sleepy while whiskey attains them want to argue.
In short, experts say this is bunk. “Alcohol is alcohol whichever way you slice it, ” pharmacologist Paul Clayton, a fellow of Oxford’s Institute of Food, Brain& Behaviour, told The Guardian.
So why do people insist that tequila attains them crazy?
One very strong possibility is that we experience the effects we expect where reference is liquor( or devour most substances ). Scientific research going back to the 1960 s demonstrate that we “learn” how to behave while drunk, and that our actual drunken behavior is a direct reflection of our expectations.
Although many people may become violent while intoxicated, people who have never associated drunkenness with conflict don’t depict the same behavior. So by that same token, if we expect that vodka will construct us want to sing karaoke, we can perhaps turn that into a self-fulfilling prophecy.
11. A juice cleanse will ‘detox’ you after an unhealthy eating binge .
The myth of the juice cleanse is a stubborn one and one frequently thus promoting celebrities but it’s both incorrect and unhealthy.
First of all, your torso naturally removes harmful substances through the liver, kidneys, and gastrointestinal tract there’s nothing about juice that will hasten that process along.
Secondly, juicing is largely a way of removing helpful fiber from fruits and vegetables many sugary fruit juices are as bad for you as sodas. You’re building the fruit less healthy by “juicing” it.
12. Everyone should booze eight glasses of water a day .
Hydration is very important, but the notion that eight glasses of water is essential is a strange one.
In healthy people, researchers haven’t found a link between fluid intake and kidney disease, heart disease, sodium degrees, or skin quality.
People get a lot of their water from foods and other liquors in the first place, but there is a good reason to booze more water. It’s a calorie free alternative to other liquors( specially sugary ones ), and people who drink water instead of those liquors devour fewer calories overall.
But in general, booze when you are thirsty you don’t need to count the glasses.
13. It’s fine to eat something if it’s been on the flooring for less than 5 seconds .
It’s the worst when something you really wanted to eat falls on the flooring. But if you grab it in five seconds, is it okay?
Sorry, but the five-second-rule isn’t a real thing. Bacteria can infect a meat within milliseconds. Moist foods attract more bacteria than dry foods, but there’s no “safe duration.” Instead, safety depends on how clean the surface you dropped the meat on is.
Whether you eat it or not after that is up to you, but if the people that stroll on that flooring are likewise walking around New York City, for example, we wouldn’t recommend it.
14. Inoculations can be risky .
This idea comes from a now thoroughly-debunked( and recanted) analyse of 12 children that appeared in 1998 in The Lancet and claimed there was a link between the MMR vaccine and autism.
It turned out that analyse wasn’t only flawed, it also contained false information that was necessary to make its point.
Since then, numerous investigates that have analyzed data from more than a million children have shown that there’s no connection between inoculations and autism.
But panics about that connection have persisted, partly spurred on by public figures building false assertions about inoculations. This contribute to scary diseases like measles coming back.
15. Yogurt will help put your digestive system back in order .
This is one of our modern health myths. Yogurt is often marketed as having advantages for digestion and as something that’ll keep people slim because of probiotics, or the “good bacteria” that’s living inside it.
Researchers have found that the bacteria in our bodies are very connected to our metabolism and obesity rates, among other things, so it seems like there’s a logical linkage here.
But we don’t yet understand how the trillions of bacteria in our bodies work well enough to manipulate them in this way. Despite the fact that the probiotic business was merit $23.1 billion in 2012, we can’t construct yogurt that will repair our inner bacterial balance.
That’s not to say that yogurt is unhealthy, just that its benefits are oversold. Plus, a lot of yogurt is packed with carbohydrate, which we do know contributes to obesity and other difficulties so if you enjoy yogurt, find a version that isn’t full of additional unnecessary calories or it might have the opposite of the intended effect.
16. An apple a period keeps the doctor away .
Apples are good for you, packed with vitamin C and fiber, both of which are important to long-term health, but they aren’t all you need.
And if certain viruses or bacteria get into your system, an apple will regrettably do nothing to protect yourself. So go ahead and get that flu shooting, even if you feed apples.
17. Eating ice cream will construct your cold worse .
If you’re home sick with a cold, you can totally go ahead and comfort yourself with some ice cream.
The idea that dairy increases mucus production is very fortunately not true, according to researchers and a medical doctor at the Mayo Clinic, who mentions “in fact, frozen dairy products can relieve a sore throat and furnish calories when you otherwise may not eat.”
Praise be.
18. Cracking your knuckles will give you arthritis .
Fortunately, this isn’t true either.
Cracking your knuckles may rile the person or persons around you, but even people who have done it frequently for many years aren’t any more likely to develop arthritis than those who don’t.
19. Starve a fever, feed a cold .
There’s a good reason you may have heard this said multiple behaviors, either “starve a cold, feed a fever” or “starve a fever, feed a cold.”
Despite a slew of headlines claiming that depriving a fever wasn’t a myth in response to a tiny and largely misinterpreted analyse in 2002, there’s no real proof to back this up. Limiting your caloric intake may actually hurt your immune system more than helping it, and it would certainly be a bad mind to not feed during the course of its 6-8 period duration of a cold.
Instead, physicians say to go ahead and feed if you are able. The more accurate face, as Scientific American notes, would be “feed a cold, feed a fever.” And make sure to get plenty of fluids.
20. It’s fine to booze sports liquors to rehydrate .
We all know that soda and similarly sugary liquors like lemonade are bad for us( right ?), but what about sports liquors like Gatorade or Powerade? Sports-focused advertise has successfully convinced a whole lot of people that downing a bottle of this material is fine, specially if you’ve gone for a jog lately it’s replacing electrolytes, after all.
But truly, for most people the amount of carbohydrate in these liquors is far more than is needed even if you’ve been exerting. Lower calorie alternatives, which many of the same corporations have created in recent years, are much better alternatives. Or merely drink water.
21. Coffee and brew dehydrate you, since caffeine and booze are diuretics .
In sufficient sums, caffeine and booze can have a diuretic influence. But the amount of caffeine in a typical cup of coffee or booze in a brew isn’t enough to really have this influence, according to one recent analyse. A moderate amount of either coffee or brew hydrates people just about as well as water does.
22. Milk does a torso good( and safeguards your bones )!
This is an incredibly successful bit of advertise that has wormed its way into our brains and policies the US Department of Agriculture tells us that adults should booze three beakers of milk a period, mostly for calcium and vitamin D.
However, multiple investigates show that there isn’t an association between boozing more milk( or taking calcium and vitamin D supplements) and having fewer fractures.
Milk is fine, but it’s not a magical health liquor. Astonishingly, however, milk is particularly hydrating similar to pedialyte, both even more hydrating than water.
23. You shouldn’t eat too many eggs, since it’ll elevate your cholesterol .
Eggs have lots of cholesterol in them. For the majority of members of us, that’s not an issue, since a growing torso of research shows that dietary cholesterol( from foods you feed) doesn’t truly have much of an effect on blood cholesterol in the great majority of people.
Thank goodness.
24. Eating fat will construct you fat .
The tide has started to swaying back the other way on this one, but recommendations regarding low-fat foods remain common.
The decision to demonize fat for its caloric density and heart-clogging consequences was largely research results of shady science influenced by a carbohydrate trade group. It turns out that the society-wide decision to cut saturated fat from diets led to increased intake of carbohydrate and processed trans fats, all of which were most likely less healthy overall.
We need a moderate amount of fat specially healthy fat in our diets.
