Eating instant noodles doesn't just lead to weight gain—it may also damage brain health. Research indicates that regular consumption of instant noodles is associated with a 25% higher risk of dementia. Experts have unraveled three major mechanisms through which instant noodles harm the brain, including high salt and trans fats that can clog brain blood vessels and trigger dementia.
The Malaysian Public Health Platform (PHM) shared on its Facebook page that many urban dwellers, for convenience, enjoy eating instant noodles, even drinking the MSG-laden soup. These poor dietary habits not only lead to obesity or high blood pressure but may also bring on early-onset dementia. A 2022 study published in JAMA Neurology by a Brazilian research team found that people who frequently consume ultra-processed foods like instant noodles, chicken nuggets, and sausages have a 25% higher risk of developing dementia compared to the general population.
Why Frequent Instant Noodle Consumption Harms the Brain?
- The Brain is "On Fire": Research indicates that most ultra-processed foods undergo extensive industrial processing and contain large amounts of synthetic chemicals, industrial preservatives, artificial flavors, and trans fats. The body may not even recognize these substances as food, potentially triggering neuroinflammation. This leads to a state of chronic low-grade inflammation in the brain, essentially "burning" memory cells daily. By the time problems are noticed, it's often too late.
- Malnutrition Leading to Brain Atrophy: Instant noodles provide mostly "empty calories" and lack the real nutrients the brain needs to survive. When the brain is fed these "fake foods" long-term, it suffers from malnutrition and starvation, eventually leading to physical brain atrophy.
- High Salt and Trans Fats Clog Brain Blood Vessels: These foods are extremely high in salt and trans fats, which gradually clog the tiny blood vessels leading to the brain. When oxygen supply to the brain is hindered and oxygen cannot reach brain cells, they suffocate and die, leading to stroke and dementia.
The PMH warns that long-term poor dietary habits could cause dementia to appear as early as around age 50. Symptoms include declining memory, confusion with directions, emotional instability, and in severe cases, affecting daily life.
Symptoms of Early, Middle, and Late-Stage Dementia
According to Hong Kong's Hospital Authority, dementia is a disease caused by deterioration of brain function due to changes in brain nerve cells. Patients' memory, comprehension, language, learning, calculation, and judgment are affected, with some also experiencing changes in emotions, behavior, and senses.
- Early Stage (Years 1-2): Symptoms are often mistaken for normal aging.
- Loss of short-term memory.
- Difficulty expressing or understanding abstract concepts (e.g., physical discomfort, feelings).
- Mood or behavioral changes.
- Difficulty learning new things or following complex instructions.
- Reduced judgment; can manage basic self-care but needs reminders.
- Middle Stage (Years 2-5): Early difficulties become more pronounced.
- Confusion between distant memories and recent reality; occasional difficulty finding words.
- Changes in behavior and personality; may become emotionally unstable.
- Requires assistance with daily activities.
- Late Stage (After Year 5): Almost completely dependent on others for care.
- Severe memory loss, forgetting familiar people and events.
- Decline in physical activity and mental state.
- Inability to express or communicate effectively.
- Cannot manage daily life; requires long-term care.
- Disrupted circadian rhythm.
