Apple A Day? A Closer Look At Popular Health Tips

There are countless health-related adages that have been passed down through the ages, but how many are based on medical truths or research findings?

From childhood advice like wearing a coat in the cold or not eating a watermelon seed, many tips have become habits, whether or not they're based on fact.

Let's take a look at some of the most popular health tips and see if they've stood the test of time.

"Starve A Cold, Feed A Fever"

Or is it starve a fever, feed a cold? No matter which variation you've heard, this piece of advice is misleading and false. Any directive to "starve" is never promising, not to mention when you're ill.

When you are sick and your body is fighting an infection, you need to feed your body to ensure it has the energy to get you back feeling well. However, you should focus on increasing your intake of immunity-boosting, hydrating, and nutrient-dense foods while avoiding things like alcohol, sugar, and ultra-processed products.

"You Shouldn't Swim After Eating"

Whether you're at a pool party, on the lake or having a waterside picnic, you might be wary of jumping in for a dip after you eat. While there are many safety tips to keep in mind on the water, experts say that there is no reason to be worried about having a bite beforehand.

Whether you are concerned you'll experience stomach cramps or that your ability in the water will be hampered by a pre-swim snack, research has shown that eating before swimming has minimal, if any, impact.

"Apple A Day Keeps The Doctor Away"

While the popular rhyme isn't the only piece of health advice you should follow, research finds there is some truth to the adage. However, it goes beyond just a single apple.

Apples have been shown to protect against cardiovascular diseases and cancer and improve oral health among a number of others health benefits. But perhaps the rhyme is more of a reminder to eat your fruits and vegetables. It's recommended everyone should consume roughly 400 grams of fruits and vegetables, or four to five servings, per day.

"Wet Hair Will Catch You A Cold"

You've likely been warned once or twice to never go outside in cold weather with wet hair unless you want to catch a cold, and researchers say there may be some truth to this piece of folklore.

While there is no definitive evidence that going outside with wet hair causes illness, some research suggests that exposure to cold temperatures may weaken your immune response. Just like dressing warmly in chilly weather, it's important to stay protected from the elements to keep you comfortable and ensure your body is not expending unnecessary energy on regulating your body temperature.

"Carrots Are Good For Your Vision"

It's true! Carrots contain Vitamin A, which is great for your vision in small quantities, according to the National Eye Institute. However, carrots should be just a part of a well-balanced diet that emphasizes dark, leafy greens like spinach and kale.

Additionally, fish that is high in omega-3 fatty acids like salmon can be an excellent source of nutrition to support not only your eyesight but your overall health as well. No matter how balanced your diet is, Ophthalmologist Dr. James Stroh with EvergreenHealth Eye Care also stresses the importance of your regular eye exams.
