What to eat to become stupid

Everyone doesn't like stupid people and hopes that they can become smart. However, whether one is smart or not depends not only on innate factors but also acquired factors. Many daily foods can make people stupid. In daily life, some foods are delicious, but they are very harmful to the brain and do no harm in the short term. But in the long run, it will make you dumber. Let's see which foods will make people dumber the more they eat.

6 types of food that make you dumber the more you eat

1. Foods containing lipid peroxides

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, contain more lipid peroxides, which will accumulate in the body, causing damage to certain metabolic enzyme systems and promoting premature brain aging or dementia.

2. Foods containing a lot of saccharin and MSG

Excessive intake of saccharin can damage brain cell tissue; MSG is safe to consume in small amounts, but it is best not for infants under one year old and pregnant women in late pregnancy. If babies consume MSG, it may cause brain cell necrosis; if pregnant women eat MSG, it will cause zinc deficiency in the fetus and affect the child's intellectual development.

3. Foods containing trans fatty acids

A 2012 study found that excessive intake of trans fats not only increases "bad" cholesterol (LDL) and lowers "good" cholesterol (HDL) levels, but also causes brain shrinkage. Trans fatty acids increase the risk of cerebral vascular degeneration and sclerosis.

4. Too salty food

The human body's physiological need for salt is extremely low; less than 7 grams per day for adults and less than 4 grams per day for children is sufficient. Eating salty food frequently will damage the arteries, affect the blood supply to the brain tissue, and cause brain cells to be in a state of ischemia and hypoxia for a long time, which will lead to memory loss and premature brain aging.

5. Foods containing lead

Lead can replace the active positions of other minerals, such as iron, calcium, and zinc in the nervous system and is therefore a major "killer" of brain cells. Foods containing lead mainly include popcorn, preserved eggs, etc. It should be noted that the lead content of "lead-free preserved eggs" is not zero, but is lower than the corresponding national standard, and is also not suitable for consumption in large quantities.

6. Foods containing aluminum

The World Health Organization points out that the human body's daily aluminum intake should not exceed 60 mg. The alum in fried dough sticks is an inorganic substance containing aluminum. If you eat 50-100 grams of fried dough sticks a day, you will exceed this amount.
