Debunking 5 Common Health Myths Singaporeans Still Believe

Published on:March 03 2025

Health myths have been passed down through generations, often rooted in cultural beliefs or anecdotal evidence rather than science. While 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 while 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), such as those offered by BUZUD, 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 prediabetes or diabetes. By using a CGM, you can enjoy durian responsibly while 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 kang kong will give you weak legs

Kang kong, also known as water spinach, is a staple vegetable in many Singaporean households and hawker centres. Despite its popularity, some people believe that eating kang kong 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 kang kong. In fact, kang kong 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 kang kong 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. While 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.

For those looking to monitor their weight and overall health more effectively, tools like the BUZUD Body Composition Scale can be incredibly helpful. Unlike traditional weighing scales, BUZUD’s Body Composition Scale provides a detailed breakdown of your body metrics, including body fat percentage, muscle mass, water content, and more. These insights allow you to track your progress more accurately and make informed adjustments to your fitness or diet plan. By focusing on overall health rather than just weight, you can achieve long-term results.

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. While 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. Tools like the BUZUD Continuous Glucose Monitor (CGM) and Body Composition Scale empower individuals to monitor their health comprehensively, providing accurate data to support evidence-based decisions. When in doubt, consult a healthcare professional for reliable information. Remember, your health is too important to leave to myths and hearsay.
