As we all know, foods such as milk, fish, carrots, and scallions are beneficial for brain health, but there are also some foods that the brain dislikes. Research has shown that regularly consuming the following 5 types of food can lead to a sluggish and clumsy brain, and even a decline in memory: excessively salty foods
The human body's physiological need for salt is extremely low. For adults, less than 7 grams per day, and for children, less than 4 grams per day is sufficient. Regularly consuming salty foods can damage arterial vessels, affect the blood supply to brain tissue, and cause brain cells to be in a long-term state of ischemia and hypoxia, leading to memory loss and premature aging of the brain.

Lead can replace other minerals such as iron, calcium, and zinc in their activities within the nervous system, making it a major "killer" of brain cells. Lead-containing foods mainly include popcorn and preserved eggs. It should be noted that "lead-free preserved eggs" do not contain zero lead; their lead content is just below the corresponding national standard and should not be consumed in large quantities either. Aluminum-containing foods
The World Health Organization states that the daily intake of aluminum by the human body should not exceed 60 milligrams. The alum in fried dough sticks is an aluminum-containing inorganic substance. Eating 50-100 grams of fried dough sticks in a day would exceed this amount. Foods containing peroxides
Fried foods with an oil temperature above 200°C and foods exposed to sunlight for extended periods, such as smoked fish, roast duck, and roast goose, contain a high amount of peroxides. These accumulate in the body, damaging certain metabolic enzyme systems and promoting premature aging or dementia of the brain. Foods high in saccharin and monosodium glutamate
Excessive intake of saccharin can damage brain cell tissue. Small amounts of monosodium glutamate (MSG) are safe to consume, but it is best for infants under one year of age and women in the late stages of pregnancy to avoid it. Consumption of MSG by infants may lead to the necrosis of brain cells; for pregnant women, it can cause zinc deficiency in the fetus, affecting the child's intellectual development.
