Instant noodles, commonly known as “mì tôm,” have become a go-to quick meal for busy individuals around the world, especially in Vietnam where they are a household staple. Their ease of preparation and comforting taste make them incredibly popular. However, nutrition experts caution that relying on instant noodles too frequently can have detrimental effects on health, particularly for specific groups of people. Despite cravings, some should strictly avoid instant noodles to maintain their well-being.

Nutritional Imbalance in Instant Noodles

Nutritionists emphasize that instant noodles are primarily composed of carbohydrates. A healthy diet, however, requires a balanced intake of six essential nutrients: protein, fats, carbohydrates, minerals, vitamins, and water. When one or more of these nutrients are missing or insufficient, it can lead to fatigue and, over time, increase the risk of serious illnesses.

Instant noodles are often lacking in protein and vitamins, and are high in unhealthy fats and sodium, contributing to poor nutritional balance. Consequently, regular consumption without adequate supplementation can negatively impact health.

Groups That Should Avoid Instant Noodles

1. People with Obesity and Cardiovascular Diseases

Instant noodles are typically fried in shortening oil, which contains high levels of saturated fats known to raise cholesterol levels and promote atherosclerosis—the buildup of plaques in arteries. This significantly raises the risk of obesity, heart disease, and stroke.

Additionally, since the main ingredient is refined starch, the body converts excess carbohydrates into fat, further exacerbating weight gain and placing extra strain on the cardiovascular system. For individuals battling obesity or heart conditions, consuming instant noodles regularly is highly discouraged.

2. Individuals with Stomach Problems

The seasoning packets in instant noodles are often rich in spices and artificial additives, which can dull taste buds over time and irritate the digestive system. For those with sensitive stomachs or diagnosed gastric issues, instant noodles can increase stomach acidity and pressure, worsening discomfort and potentially triggering gastritis or ulcers.

Moreover, instant noodles are difficult to digest. Studies show that noodles can remain intact in the stomach for up to two hours, interfering with nutrient absorption and prolonging exposure to harmful substances, which may aggravate digestive problems.

3. Patients with Kidney Disease

A high sodium content is a common issue with instant noodles. The total salt in the noodles and seasoning packets can amount to about one-third of the daily recommended salt intake for an adult. For people with kidney disease, who need to strictly control sodium consumption to avoid fluid retention and high blood pressure, instant noodles pose a serious health risk.

4. Young Children

Children are often drawn to the flavorful and convenient nature of instant noodles, sometimes developing a strong preference or even dependence. However, instant noodles do not meet the high nutritional needs of growing children and mainly provide “empty calories,” which lack essential vitamins and minerals.

Furthermore, because instant noodles are hard to digest, prolonged digestion time can cause bloating, reduce appetite, and hinder nutrient absorption. This can negatively affect children’s growth and overall health.

The Hidden Dangers of Frequent Instant Noodle Consumption

Regular consumption of instant noodles is linked to several chronic health concerns beyond the groups mentioned above. Excessive intake of processed foods high in saturated fats and sodium has been associated with increased risks of hypertension, diabetes, and metabolic syndrome.

Experts warn that the preservatives and flavor enhancers used in instant noodles, such as monosodium glutamate (MSG) and tertiary butylhydroquinone (TBHQ), may have adverse long-term effects when consumed frequently.

For those who enjoy instant noodles but want to mitigate health risks, consider:

• Adding fresh vegetables and lean protein (e.g., chicken, tofu) to enhance nutritional value.

• Using only part of the seasoning packet to reduce sodium intake.

• Choosing brands that offer lower sodium and preservative-free options.

• Limiting instant noodle consumption to occasional meals rather than regular diet staples.
