Have you ever wondered if coffee truly stunts your growth or if chilly, wet weather leads to a cold? Let's separate fact from fiction and examine six common health myths and uncover the truth behind them.


March 11, 2024

When it comes to health and wellness, it's easy to get caught up in myths and misconceptions. From well-meaning advice passed down through generations to the latest trends that promise miraculous results, it can be challenging to determine what is truly beneficial for our well-being. In this blog post, we’re debunking health myths and shedding light on the truth behind these misconceptions.

Does Coffee Stunt Your Growth?

One of the most common health myths is that coffee can stunt your growth. However, there is no scientific evidence to support this claim. Coffee contains caffeine, a stimulant that can temporarily increase heart rate and blood pressure, but it does not have any direct impact on bone growth or height. Factors such as genetics, nutrition and overall health play a more significant role in determining an individual's growth and development. While coffee itself may not stunt growth, it is important to emphasize moderation, especially in adolescents. The American Academy of Pediatrics recommends that children under the age of 12 avoid caffeine altogether, while those between 12 and 18 should limit their intake to no more than 100 mg per day.1 This recommendation is based on concerns about potential negative effects of caffeine on sleep patterns and behavior. Parents should make sure they are mindful of their children's intake of caffeine and promote healthier options for staying hydrated and energized. The idea that coffee hinders growth likely stems from the belief that caffeine can interfere with calcium absorption. While excessive caffeine consumption may have a slight effect on calcium absorption, it is unlikely to have a significant impact on overall growth.

Are Egg Yolks Bad for You?

You may believe the myth that egg yolks are bad for your health due to their cholesterol content. While egg yolks do contain cholesterol, it is now understood that dietary cholesterol has a minimal impact on blood cholesterol levels for most individuals. The American Heart Association states that it is the saturated and trans fats in our diet that have a greater impact on blood cholesterol levels, not dietary cholesterol.2 Moderate egg consumption, including the yolks, can be part of a healthy diet. In fact, eggs are a good source of essential nutrients such as vitamins A, D, E and K, as well as omega-3 fatty acids and protein.

Eggs, including the yolks, are a rich source of protein and contain a relatively low number of calories. With approximately six grams of protein and only 70 calories per large egg, they provide a balanced nutritional profile that supports overall health and wellness.3 Remember to cook eggs thoroughly to ensure food safety and enjoy the many benefits that eggs offer as part of a well-rounded diet.

It is important to note that individuals with certain health conditions, such as diabetes or heart disease, may need to limit their intake of dietary cholesterol. As with any dietary consideration, it is always advisable to consult with a health care professional for personalized guidance based on your specific health needs.

Does Cracking Knuckles Cause Arthritis?

The age-old belief that cracking your knuckles leads to arthritis has been a common health misconception. However, scientific research has debunked this notion. Cracking your knuckles is simply the result of gas bubbles being released from the joints, and it does not cause any long-term damage or increase the risk of developing arthritis. Multiple studies have found no significant association between knuckle cracking and arthritis.4 While excessive or forceful knuckle cracking may cause temporary discomfort or swelling, it does not lead to chronic joint conditions. It is important to note that if cracking your knuckles causes pain or discomfort, it may be a sign of an underlying joint issue, and it is advisable to consult a health care professional.

Does Chilly, Wet Weather Cause a Cold?

Contrary to popular belief, cold, wet weather does not directly cause a cold. The common cold is caused by viruses, specifically rhinoviruses, and not by the temperature or dampness of the environment. However, there might be some indirect factors at play. During colder months, people tend to spend more time indoors near others, which increases the likelihood of coming into contact with the virus. Additionally, cold weather can lead to a decrease in humidity, which may dry out the nasal passages, making them more susceptible to viral infections. So, while cold, wet weather itself doesn't cause a cold, it can create conditions that make it easier for the virus to spread and for individuals to become more susceptible to catching a cold.

Is Sunscreen Needed If the Sun Isn’t Out?

While the intensity of the sun's rays may be reduced on cloudy or overcast days, it is still important to wear sunblock. The sun emits ultraviolet (UV) radiation, which consists of UVA and UVB rays. These rays can penetrate through clouds and even on overcast days, posing a risk to your skin. UVA rays can penetrate deeper into the skin and contribute to premature aging and skin damage, while UVB rays are the primary cause of sunburn. Therefore, it is important to protect your skin from these harmful rays by applying sunblock, regardless of whether the sun is out or not. Remember, protecting your skin from UV radiation is a year-round commitment, so make it a habit to wear sunblock daily, even on cloudy days.

Choosing the right sunscreen: When selecting a sunblock, opt for a broad-spectrum formula that protects against both UVA and UVB rays. Look for a sun protection factor (SPF) of 30 or higher, as this provides enough protection for most individuals.

Does Chocolate Cause Acne?

While there is no conclusive evidence that chocolate directly causes acne, it is important to consider the quality and composition of the chocolate consumed. Not all chocolate is the same. If you consume chocolate that contains high amounts of corn syrup, sugar, fillers, dairy and additives, these ingredients can potentially contribute to the development of acne breakouts. Therefore, it is advisable to be mindful of the ingredients in the chocolate you consume, as they may have an impact on your skin health.

By debunking health myths, we aim to provide you with accurate information to make informed decisions about your lifestyle choices. Don't let common health misconceptions dictate your wellness decisions. Separate fact from fiction and empower yourself with evidence-based knowledge for a healthier and happier life.
