At some point in your life, you’ve likely been given some health-related advice that — though it may have sounded good in theory — isn’t actually true. Perhaps it was based on superstition or was passed down through generations. Maybe you heard a friend or a relative say it and it sounded sensible.
But following advice without knowing all of the facts may not be wise — especially when it comes to your health.
We gathered nine health myths that you’ve likely heard before, and did a little digging on them. Here’s what we found…
1. Swimming after eating
Have you ever been warned to stay out of the pool after eating so you don’t drown? Sounds dramatic, but the idea is that your digestive system will drain the blood from your limbs, weakening your ability to swim.
While digestion does require blood, it certainly won’t drain your limbs. They can function totally fine after a meal. If you take a swim after eating, the worst thing you may experience is a minor cramp — but such is the case with most exercises following a meal. 
2. Five-second rule
The five-second rule dictates that when you drop food on the floor, you have five seconds before the transfer of germs is complete. Meaning, if you pick up the food within five seconds, no harm, no foul.
This rule is great for when you have a tasty treat, drop it by mistake, and still want to enjoy it. We’ve all been there. That was a five dollar donut! But sadly, the five-second rule is simply not true.
According to research, the second that your donut hits the ground, it has germs on it — regardless of how much it cost.
One study found that most of the germs tested transferred to the food instantaneously. However, in some cases, the longer the food remained on the surface, the more germs it gathered.
It may also depend slightly on what kind of food. For example, that same study found that — when testing various foods for picking up germs — watermelon picked up the most, while gummy bears picked up the least. 
That being said, no food picked up none of the germs. So, use your best judgement (especially if no one is looking!).
3. It takes seven years to digest swallowed gum
We have great news. If you’ve swallowed gum within the last seven years, you’re not still digesting it!
Though the synthetic ingredients in most gums are difficult to digest, the body can work through it within just a few days.
That being said, it’s still unhealthy to swallow gum, and is considered dangerous to swallow large amounts, as it can lead to intestinal blockages. If you’re chewing gum, it’s in your best interest to discard it in a way other than swallowing it.
4. Coffee stunts child growth
When you were young and wondering what coffee was all about, you may have heard that you can’t have any because it will stunt your growth. But that’s just not true.
However, coffee can have other negative effects that could impact a child more than an adult. Along with the nervousness, trembles, and increased heart rate that can come with coffee intake, children who regularly consume coffee may be inhibiting their calcium intake — which they need a lot of as they grow.
That being said, limited coffee intake may also have positive health effects!

5. Humans only use ten percent of their brains
According to a 2013 review in Psychology Learning and Teaching, the notion that humans only use ten percent of their brains is one of the most common misconceptions out there.
Brain imaging such as PET scans and fMRI have found that the entire human brain is active at all times, even when we’re asleep!
6. Food with mayonnaise spoils faster
This is one of those pieces of advice that feels like it makes sense, despite it being untrue.
Mayonnaise contains eggs, which is why it’s reasonable to think that it would spoil faster, especially when in the sun at a barbecue or outdoor event. However, most store-bought mayonnaise contains acidic ingredients which allows the mayonnaise to keep longer. 
This means that, in some cases, mayonnaise may actually prolong the shelf life of certain foods! But this doesn’t mean that your mayonnaise-based foods are now invincible. It just means that they’re not necessarily going to spoil faster than any other food at the potluck!
7. Hair of the dog
Hair of the dog is the idea that, if you’re experiencing a hangover, having a drink with breakfast will help it go away. However, there is no evidence to support this. In fact, research shows that this will only make things worse in the long run (in the short-term you may feel better, but that is only the alcohol numbing the hangover symptoms).
The name stems from the misguided notion that you could recover from a dog bite by plucking a hair from the dog and holding it to the wound.
But, as it turns out, having a drink with breakfast does not alleviate a hangover any better than holding dog hair up to a bite will help heal the wound.
8. Chocolate causes acne
This one is perhaps half true.
Where it’s wrong is in blaming chocolate solely. Chocolate itself shouldn’t cause acne. In fact, chocolate — especially dark chocolate — has plenty of health benefits.
Where this is correct is that many “chocolate bars” are filled with sugars and other additives that can have a negative impact on skin health.
If you want to have chocolate without worrying about acne, make sure you’re getting dark chocolate that isn’t filled with unnecessary sugar or other ingredients.
9. Get your hair squeaky clean
You may have been told to clean, lather, and scrub your hair until you can hear it squeaking between your fingers. However, this may actually damage your hair.
Washing your hair too thoroughly can remove the natural oils of the scalp and hair. Instead, you should gently lather your scalp, work the shampoo carefully through the length of your hair, and rinse in lukewarm water.
If you have a particularly oily scalp — perhaps you sweat a lot from exercise, live somewhere humid, or have very thick hair — then washing more frequently and more thoroughly is a good idea. But for everyone else, being easier on your hair in the shower is best.
One that is true…
One piece of health advice that you’ve likely heard before is to eat your fruits and vegetables. Because fruits and veggies contain nutrients, antioxidants, and other crucial things that help your body function at its best — this is good advice!
But due to soil degradation, you may not be getting as much out of your food as you may think. One study found up to a 37% drop in certain nutrients between the years 1975 and 1997! 
One can only wonder — how much more has been lost since?
Another issue is that, as we age, our bodies can have a tougher time absorbing vitamins and minerals. 
This is why, here at PuraTHRIVE, our supplements are designed to be absorbed. That way, you can get the most out of every dose! We also use the best quality ingredients we can find and do third-party testing on every batch so that we can be sure we’re offering the best product possible!
