Quick action today: question health advice critically and consult professionals when in doubt.
Health myths have been passed down through generations, often rooted in cultural beliefs or anecdotal evidence rather than science. Whilst these misconceptions are usually shared with good intentions, they can lead to unnecessary worry, confusion, or even prevent people from making informed health decisions. In Singapore, where traditional practices and modern medicine often intersect, some of these myths persist. Let's take a closer look at five of the most common health myths and uncover the truth behind them.
Myth #1: Eating Too Much Durian Can Cause a Fever
Durian, often referred to as the "king of fruits," is a beloved delicacy in Singapore and across Southeast Asia. However, many people believe that eating too much durian can cause a fever. This belief likely stems from the fruit's association with being a "heaty" food in Traditional Chinese Medicine (TCM).
From a scientific perspective, this is not true. Dr Michael Wong, deputy medical director of Raffles Medical, explains that whilst digestion can slightly raise body temperature due to metabolic processes, it does not cause a fever. A fever is typically a response to infection or inflammation, not overeating durian.
That said, durian does have a "warming" effect in TCM, which means it can cause discomforts such as sore throat, mouth ulcers, or constipation if consumed in excess. This is why moderation is advised. Additionally, durian is high in sugar and calories, so overindulgence can contribute to weight gain or spikes in blood sugar levels, especially for those with diabetes.
For individuals concerned about the impact of durian on their blood sugar, a Continuous Glucose Monitor (CGM) can be an invaluable tool. A CGM provides real-time data on blood glucose levels, allowing users to see how their body responds to specific foods, including durian. This empowers individuals to make informed dietary choices and manage their health more effectively, especially for those with pre-diabetes or diabetes. By using a CGM, you can enjoy durian responsibly whilst keeping your blood sugar levels in check.
Myth #2: Drinking Cold Water Worsens Period Cramps
Cold water has long been vilified in traditional beliefs, with claims that it can disrupt digestion, slow blood circulation, or worsen menstrual cramps. Many women in Singapore have likely been told to avoid cold drinks during their period to prevent discomfort.
However, modern medical research debunks this myth. According to MedPark Hospital in Bangkok, menstrual cramps are caused by uterine contractions triggered by the release of prostaglandins, not the temperature of the beverages you consume. Your body is highly efficient at regulating its internal temperature, so drinking cold water only affects the digestive tract temporarily and has no impact on the reproductive system.
That said, individual experiences vary. Some people may feel uncomfortable drinking cold beverages during their period, and that's perfectly valid. Listening to your body is always a good approach. If you find that warm drinks help ease cramps, there's no harm in sticking to them.
Myth #3: Eating Kangkong Will Give You Weak Legs
Kangkong, also known as water spinach, is a staple vegetable in many Singaporean households and hawker centres. Despite its popularity, some people believe that eating kangkong can weaken the legs. This myth likely originates from its hollow stems, which are thought to symbolise fragility, or its "cooling" properties in TCM.
Scientifically, there is no evidence to support this claim. Sports physician Dr Roger Tian explains that weak or tired legs are usually caused by factors such as poor muscle strength, lack of exercise, or fatigue, not by eating kangkong. In fact, kangkong is a highly nutritious vegetable, rich in vitamins A and C, iron, and antioxidants. It's a great addition to a balanced diet and can support overall health.
Interestingly, one Malaysian publication even conducted an experiment to debunk this myth. They had an intern eat kangkong three times a day for three days straight, and he experienced no leg cramps or weakness. So, the next time someone tries to use this myth as an excuse to avoid eating their greens, you can confidently set the record straight.
Myth #4: Spicy Foods Cause Stomach Ulcers
Singaporeans love their spicy food, from fiery sambal to tongue-numbing mala hotpots. However, there's a persistent belief that eating too much spicy food can cause stomach ulcers. This myth likely stems from the discomfort some people feel after consuming very spicy meals, such as heartburn or indigestion.
The truth is, spicy food does not cause stomach ulcers. According to gastroenterologist Dr Edwin McDonald of UChicago Medicine, the primary causes of ulcers are frequent use of nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or aspirin, and infection with Helicobacter pylori (H. pylori), a common stomach bacteria. These factors damage the stomach lining, leading to ulcers.
In fact, capsaicin, the compound that gives chillies their heat, has been shown to reduce stomach acid production and may even help protect the stomach lining. However, if you already have an ulcer or a sensitive stomach, spicy foods can irritate the condition and worsen symptoms. Moderation is key, and if you experience persistent stomach pain, it's best to consult a doctor.
Myth #5: Drinking Lemon Water Helps You Lose Weight
Lemon water is often promoted as a miracle drink for weight loss, with claims that it can boost metabolism, burn fat, or detoxify the body. This myth has gained traction thanks to social media and celebrity endorsements, but it's not supported by science.
Dietitian Caroline Thomason explains that there is no magical food or drink that can directly cause weight loss. Whilst drinking water before meals can help you feel fuller and reduce calorie intake, adding lemon does not provide any special fat-burning benefits. Weight loss ultimately comes down to maintaining a calorie deficit through a balanced diet and regular exercise.
That said, lemon water does have its benefits. It's a refreshing way to stay hydrated, and lemons are a good source of vitamin C and antioxidants, which support immune health and skin health. If you enjoy drinking lemon water, there's no harm in including it in your routine, but don't rely on it as a weight-loss solution.
Why These Myths Persist
Many of these myths persist because they are deeply rooted in cultural traditions or passed down through generations. They are often shared with good intentions, as family members or friends want to offer advice based on their own experiences or beliefs. However, it's important to question these claims and seek evidence-based information.
In Singapore, where traditional practices like TCM coexist with modern medicine, it's common for people to blend both approaches to health. Whilst TCM offers valuable insights, it's essential to distinguish between cultural beliefs and scientific facts to make informed decisions about your well-being.
Health myths can be harmless in some cases, but they can also lead to unnecessary worry or prevent people from seeking proper medical care. By understanding the facts behind these common misconceptions, you can make better choices for your health and avoid falling for outdated or inaccurate advice. Of course, when in doubt, consult a healthcare professional for reliable information. Remember, your health is too important to leave to myths and hearsay.
How to Approach Health Myths: A Balanced Perspective
Health myths often arise from cultural traditions or personal anecdotes, and while they can offer comfort or guidance, they may also mislead. Here are some tips to navigate health information wisely:
1) Consider the source
Look for information backed by scientific research or reputable health organisations rather than hearsay or social media trends.
2) Understand individual differences
What works or feels true for one person may not apply to another. Personal health conditions and sensitivities matter.
3) Use technology to personalise
Tools like Continuous Glucose Monitors (CGMs) can provide real-time feedback on how your body responds to foods and habits, helping you make informed choices.
4) When in doubt, consult professionals
Healthcare providers can help clarify myths, provide personalised advice, and guide you towards evidence-based practices.
