First, lead food
Lead is a major "killer" of brain cells. Excessive amounts of lead in food can damage the brain and cause mental retardation. Some children often eat popcorn. As the popcorn is subjected to high pressure heating during the production process, part of the lead on the inner surface of the soft lid of the lid will turn into gaseous lead. During the production process of preserved eggs, lead oxide and lead salts are contained in the raw materials. Lead has extremely strong penetrating power. Eating preserved eggs also affects intelligence. Pregnant women drink too much beer, lead in the German liquid can reach the fetus through the placenta, damage intelligence.
Second, aluminum food
The World Health Organization proposed that the daily intake of aluminum should not exceed 60 milligrams. If you eat 50 to 100 grams of fritters a day, you will exceed this allowable intake, leading to memory loss and dull thinking ability. Therefore, breakfast should not rely on oil as a staple food. Frequent use of aluminum pan cooking, aluminum kettle boiled water should also pay attention to the problem of increasing the amount of aluminum.
Third, foods containing peroxy lipids
Peroxy lipids are harmful to the human body. If long-term intake of lipids from the diet and accumulation in the body can cause damage to certain metabolic enzyme systems in the human body, promoting premature aging of the brain or dementia. Which foods contain more peroxylipids? There are mainly fried foods with oil temperatures above 200°C and foods exposed to the sun for a long time, such as smoked fish, roast duck, and roast goose. There are also oils that are fried in fish and shrimp that quickly oxidize and produce peroxy lipids. Other foods such as dried fish, cured meat, and foods containing more fat can cause haematoxylin and lipid peroxidation in the air. For these foods, children should not eat or eat less.
4. Foods containing more saccharin and MSG
The amount of saccharin should be limited, otherwise it will damage the brain, liver and other cell tissues, and even induce bladder cancer. The World Health Organization has proposed that adults should not consume more than 4 grams of MSG per day, and infants within the age of 1 year and under should be fasted. Animal experiments have suggested that infants born within the age of eating MSG may cause brain cell necrosis. Pregnant women in late pregnancy eat more MSG, can cause fetal zinc deficiency, affect the child's physical and mental development after birth, is not conducive to intellectual development.
Fifth, salty food
The physiological needs of the human body for salt are very low. Adults have less than 7 grams per day and children have less than 4 grams per day. People who are used to eating salty foods not only cause high blood pressure and arteriosclerosis, but also damage arteries and affect brain tissue. The blood supply makes the brain cells in a state of hypoxia and ischemia for a long time, and the mental retardation, memory decline, and even premature aging.
