There are some chemical elements that can also profoundly affect intelligent functions, and these trace elements have amazing power. The most noteworthy among these intelligence-enhancing chemical elements are: boron, iron, and zinc.

Chemical elements have specific effects on improving intelligence. Some enhance memory, some promote thinking speed, and some help strengthen concentration. In the absence of these chemical elements, children's intelligence will be greatly reduced. On the contrary, as long as the child is provided with sufficient intelligence-enhancing chemical elements, the child's learning and reaction abilities can be greatly improved.

Trace amounts of boron can improve intelligence

Dr. Bennant of Cranforx, USA, asked 15 people to take turns eating low-boron foods and high-boron foods for 4 months. When they ate low-boron foods, the electrical wave activity in their brains slowed down, indicating that their brains' intelligent responses also slowed down.

Dr. Bennant pointed out that the "awake waves" in their brain waves decreased and the "drowsy waves" increased. When the experimental subjects consumed less boron, they were unable to do many extremely simple brain tasks. They tap their fingers slower than before, track targets on the screen with electronic toys less accurately than before, and pick letters less quickly. In short, their intellectual reactions have all slowed down.

When experimenters ate high-boron foods, their brain wave responses increased and their brain speed was greatly improved. This surprised Dr. Bennant: "It's incredible that the brain can respond so sensitively to such a small nutritional difference. This is a brand new discovery!" So how much did the high-boron foods consumed by these experimental subjects contain? What about boron? Only 3 milligrams!

What foods can we get boron from? General dried fruits, beans, leafy vegetables such as broccoli, and fruits such as apples, pears, peaches and grapes. If you get 3 mg of boron, just eat two apples (1 mg of boron) plus half a tael of peanuts (2 mg of boron).

The impact of iron on brain waves

Oxygen is the main source of nourishing the brain. The more adequate the oxygen supply, the easier it is to improve brain intelligence. The oxygen supply to brain cells depends on red blood cells transported to the brain through the blood. The component of red blood cells that carry oxygen is heme, and the main component of heme is iron.

Therefore, patients with anemia caused by iron deficiency naturally lack nourishment for the brain, and it is expected that their intellectual reactions will be poor.

People who consume less vitamin B show signs of nerve damage. Those who eat enough vitamin B have better memory tests. People who eat enough carotene have the best thinking skills. But the most amazing thing is Those elderly people who eat high amounts of iron actually have brain waves that are as fast as young people! This means that iron is very helpful in improving intelligence. Iron-containing foods include dark green vegetables, liver, shelled sea fish, lean meat and soybeans.

Zinc, which strengthens memory and attention

Dr. Bennant’s colleagues in North Dakota, USA, have also made some new discoveries about zinc’s intelligence-enhancing effect. In a seven-month scientific experiment, a group of men and women who ate foods low in zinc performed worse on 10 of 15 intelligence tests than those who ate foods with sufficient zinc. Dr. Harold Sanshi of Texas Medical College found that healthy men and women who consumed slightly lower amounts of zinc performed poorly on tests of memory and attention. But when the amount of zinc is increased, their word memory ability improves quickly, and at the same time, their memory and attention improve.

I hope parents will feed their children more foods containing boron, iron and zinc, which are smart-enhancing chemical elements, to enhance their children’s memory and attention.

Scientific zinc supplement for health and intelligence

Zinc is an indispensable trace element in the human body. If the human body lacks this element, various discomforts will occur. It has a wide range of effects in ensuring the integrity of the body's immune function, promoting tissue repair, and the activities of various enzymes in the body. For example, if a broken hand or foot is put on a piece of adhesive tape, it will grow back quickly. The reason is that the adhesive tape contains zinc oxide. It is also noteworthy that zinc can play an important role in children's intellectual and physical development. If a child is deficient in zinc, he or she will have a dull sense of taste, loss of appetite, stagnant growth and development, and even become dwarf-like and have low intelligence.

Zinc deficiency usually has two causes. First, during the development and growth period of the fetus, when the zinc content of the mother's body tissues is low and the zinc content of the mother's white blood cells is low, the newborn's height and growth of the occiput, forehead, and head circumference are significantly delayed. If the mother is severely deficient in zinc, the fetus will develop abnormally, the brain will be underdeveloped, and the baby may develop dementia after delivery. The second is partial eclipse and anorexia, resulting in insufficient food sources and insufficient zinc intake.

Zinc is very important for human growth and health. However, the human body does not require much zinc. An adult weighing 50 kilograms has a total zinc content of 1.36 to 2.32 grams. These zincs are widely found in common foods. Animal foods such as beef liver, beef, pork, eggs, etc. are extremely rich in zinc. Plant foods such as peanuts, walnuts, carrots, potatoes, cucumbers, tomatoes, lettuce, apples, oranges, etc. also contain a lot of zinc. The average person's dietary intake of zinc can reach 10 to 15 mg per day. Therefore, as long as the diet is extensive and the gastrointestinal function is good, generally healthy people will not be zinc deficient and do not need to supplement zinc.

If the body is diagnosed with zinc deficiency, it is necessary to consciously supplement zinc with food or medicine.

Children are in a period of vigorous growth and development, and their demand for zinc is relatively large, so they may be zinc deficient. If a child is found to be anorexic, you can suspect whether he is zinc deficient. When a doctor diagnoses zinc deficiency, you can appropriately supplement zinc under the guidance of a doctor. In addition, it may also be due to regional zinc deficiency that the zinc content in vegetables, grains, and meat foods is insufficient. Eating overly refined foods can also cause zinc deficiency.

In addition to eating more foods high in zinc, people with zinc deficiency can also supplement zinc salts appropriately under the guidance of a doctor, such as taking zinc sulfate orally, but do not take too much zinc, otherwise It can cause zinc poisoning, anemia symptoms such as loss of appetite, and even vomiting and diarrhea.

How to ensure that the human body can absorb sufficient amounts of zinc requires attention to the structure of the daily diet and the reasonable combination of various foods. Animal foods are a reliable source of zinc, so people who prefer vegetarian diets are prone to zinc deficiency. For general non-disease zinc deficiency, food zinc supplementation is more convenient and safer than drug zinc supplementation. Here are some food zinc content values ??for reference. Calculated in milligrams of zinc per 100 grams of food, foods with higher zinc content include: oysters 148.7, beef 5.66, mutton 5.3, pork 1.89, peanuts 3.24, beef liver 3.92, and malt 10.1. Others include: milk 0.35, eggs 1.3, fresh tomatoes 0.24, potatoes 0.87, rice 1.5, and oatmeal 1.8.
