Debunking 10 Common Health Myths: Stop Falling for Pseudoscience!

In our daily lives, we often hear health claims that sound plausible but lack scientific evidence. These myths often masquerade as "science," leading people to believe them. Today, we'll debunk 10 common health myths to help you understand the truth and avoid misinformation.

Myth 1: MSG Causes Cancer

MSG (monosodium glutamate) is a common seasoning used in cooking. Some people worry it causes cancer. However, MSG's main component is sodium glutamate, an essential amino acid found in proteins. Glutamate is naturally abundant in foods like tomatoes, cheese, and mushrooms. Our bodies also produce glutamate for various physiological functions. The Joint Expert Committee on Food Additives (JECFA), a joint initiative of the World Health Organization (WHO) and the Food and Agriculture Organization of the United Nations (FAO), considers MSG a safe food additive. Numerous studies have shown that MSG, consumed within normal limits, does not cause cancer or other health problems.

Myth 2: Soy Sauce Turns Your Skin Dark

Some believe that long-term consumption of soy sauce darkens the skin. This is a misconception. Skin color is primarily determined by genetics and melanin levels, not diet. Soy sauce is made through the fermentation of soybeans and wheat, containing amino acids, polysaccharides, and other nutrients beneficial for health. While soy sauce has a dark brown color, it doesn't directly affect skin pigmentation. Conversely, some studies suggest that the melanin in soy sauce has antioxidant properties, potentially aiding in preventing skin aging.

Myth 3: Instant Noodles Require Detoxification

Instant noodles are popular due to their convenience. However, they are often labeled as "junk food," leading some to believe they require "detoxification" after consumption. In reality, our bodies have a robust detoxification system, including organs like the liver and kidneys, effectively eliminating toxins and waste products. Simply eating instant noodles doesn't significantly burden the body with "toxins." After consuming instant noodles, the most important thing is to complement your diet with nutrient-rich foods like vegetables and fruits for balance, rather than blindly "detoxifying." Of course, instant noodles are relatively low in nutrition and high in sodium. It's advisable not to consume them excessively, but moderate enjoyment is fine without worrying about "poisoning."

Myth 4: Food Combinations Are Untrustworthy

"Food combining" is an age-old dietary concept that suggests certain food combinations create "toxins" and health problems. Common examples include "crabs shouldn't be eaten with persimmons" or "white wine shouldn't be paired with pickled mustard greens." However, these claims are mostly unsubstantiated. The nutritional and pharmacological properties of food are relatively stable and don't change when consumed with other foods. Some so-called "incompatible" combinations, like tomatoes and cucumbers, might actually provide nutritional synergy. While certain food combinations might affect the absorption of some nutrients or cause discomfort, these situations are fundamentally different from the concept of "food incompatibility."

Myth 5: The False "Viagra" of Garlic Chives

Folklore suggests that garlic chives have "viagra" properties, making them a "must-eat" food for men. However, this claim is not scientifically proven. While garlic chives are rich in vitamins, minerals, and dietary fiber, they don't possess any specific "viagra" effect. Male sexual function depends on various factors like endocrine levels, psychological state, and lifestyle. Simply consuming a particular food doesn't have a decisive impact. Overemphasizing the "viagra" effect of garlic chives might mislead people. Maintaining a balanced diet, engaging in moderate exercise, and adopting healthy habits are crucial for men's health.

Myth 6: Sweating Out a Cold

Many people believe that sweating is the key to "detoxifying" and recovering from a cold. However, this practice is not only unhelpful but potentially harmful. Colds are caused by viral upper respiratory infections. Sweating doesn't help the body eliminate viruses. On the contrary, excessive sweating can lead to dehydration, worsening discomfort. During the initial stages of a cold, rest, drink plenty of warm water, and use fever-reducing pain relievers when necessary, rather than blindly seeking "sweating."

Myth 7: Carrots Prevent Myopia

Carrots are rich in -carotene, which the body can convert into vitamin A, essential for maintaining eye health. However, this doesn't mean eating carrots prevents myopia. Myopia develops primarily due to factors like eye axial length, corneal curvature, and isn't significantly related to vitamin A intake. Numerous studies show that the main risk factors for myopia include prolonged near-distance eye use, insufficient outdoor activities, and genetics. Preventing myopia involves practicing good eye hygiene, increasing outdoor time, undergoing regular eye exams, rather than relying on a single food.

Myth 8: Exercising Immediately After Meals

The saying "walk 100 steps after a meal, and you'll live to be 99" is common, but it's not a scientifically sound suggestion. Engaging in vigorous exercise immediately after eating is not only unhealthy but can also be harmful. After eating, the digestive system requires significant blood supply for food digestion and absorption. Exercising immediately diverts blood from the digestive tract to the muscles, hindering digestive function and causing abdominal discomfort. Exercise also accelerates gastric juice secretion, potentially aggravating acid reflux, indigestion, and other problems. It's healthier to rest for 30 minutes to an hour after meals to allow the body to complete digestion before engaging in moderate exercise. The intensity should be gradual to avoid overloading the body.

Myth 9: Mosquitoes Prefer Type O Blood

There's a claim that mosquitoes "favor" people with type O blood, making them more susceptible to bites. However, mosquitoes choose targets based on signals like odor, body temperature, and carbon dioxide levels, not blood type. Individual variations in body chemistry, such as metabolic rate and skin bacteria types, can influence mosquitoes' "preferences." Research has found that certain compounds released by the body, like lactic acid and carboxylic acids, attract mosquitoes. This has nothing to do with blood type. The danger of mosquito bites lies in the potential transmission of diseases like dengue fever and malaria. Preventing mosquito bites requires effective protective measures like using mosquito repellents, wearing long sleeves and pants, rather than solely focusing on blood type.

Myth 10: Drinking Vinegar Softens Fish Bones

Fish bones lodged in the throat are a nightmare for many people. Many believe drinking vinegar can soften fish bones for easier removal. However, fish bones are primarily made of calcium, and while acetic acid in vinegar has some dissolving power, it's difficult to achieve the effect within the body. Drinking vinegar won't soften fish bones; it might even irritate the throat and worsen discomfort. If a fish bone gets stuck in your throat, stay calm, try to remove it using your fingers or by gargling. If you can't handle it yourself, seek immediate medical attention. Don't blindly rely on home remedies. Preventing fish bones from getting stuck involves chewing thoroughly, carefully inspecting the fish, and using tools to remove bones when necessary.

Myths persist because they often cater to people's hopes and fears about health. However, truly beneficial health knowledge should be based on scientific research and professional advice. Facing the complex world of health information, we must learn to think critically, use a discerning mind to separate truth from falsehood, and avoid being misled!
