Eating the right foods can boost intelligence, while certain foods affect alertness, memory, mood, and the nervous system, harming brain health. The latest issue of the American "Daily Medical News" published a list of "Six Foods Most Harmful to the Brain," confirmed by research.
Caffeine
Dr. Lauren Napolitano, a psychologist at Bryn Mawr Hospital in Pennsylvania, states that people with psychological problems should avoid caffeine. Many people try to combat symptoms like drowsiness by drinking coffee, but they inadvertently trap themselves in a state of anxiety.
MSG (Monosodium Glutamate)
Research has found that consuming excessive MSG not only causes headaches and chest tightness but also severely impacts brain health. This is because MSG overstimulates nerve cell receptors and can even lead to the apoptosis (death) of nerve cells.
Processed Foods with Preservatives
Processed foods contain ingredients such as preservatives, artificial colors, and artificial flavors that affect behavior and cognitive brain function.
High Salt
Medical research indicates that excessive salt intake may indirectly lead to memory decline and gradually affect a person's intelligence. Multiple studies have confirmed that salt levels in the body are directly proportional to blood pressure. When blood pressure rises beyond a certain point, the brain suffers continuous, minor damage, which can affect certain brain functions, including intelligence.
Sugar
A high-sugar diet can lead to the glycation and denaturation of proteins, causing nerve damage, weakening intelligence, and accelerating brain aging. Children accustomed to high-sugar diets perform poorly on intelligence tests and have unstable moods. Surveys show that the proportion of sucrose in the diet is negatively correlated with academic performance and IQ. Diets low in nutrients and high in sucrose have a significantly adverse effect on learning. Fructose reduces brain and memory function, and long-term, excessive sugar consumption can lead to problems like memory decline.
Trans Fats
Excessive intake of trans fats not only raises "bad" cholesterol and lowers "good" cholesterol levels but also leads to brain atrophy. Trans fatty acids increase the risk of cerebral vascular degeneration and hardening.
