Eat pig brain "brain"? Unreliable rumor: Because there is a folk saying that "what you eat can make up for what you eat", eating pig brain becomes a way for some people to "make up for the brain".
Fact: Ruan Guangfeng, head of the National Science and Technology Department of the Research Center, told the Beijing News reporter that taking100g pig brain as an example, it contains particularly few vitamins, and nutrients such as calcium, iron and zinc are not sufficient. However, the saturated fatty acids and carbohydrates in pig brain are not low, which is likely to "replenish the brain" and lead to obesity.
Some people think that besides pig brain, cow brain and sheep brain can also "replenish brain". Ruan Guangfeng showed that the brains of other small animals are basically the same, all with high fat and less vitamins and minerals, so it is unhealthy to eat more.
Eat fish to "brain"? Rumor that it doesn't work for adults: it is widely circulated on the Internet that fish is beneficial to the brain. "Eating fish and drinking fish head soup can make people smart."
Fact: Fish contains rich and colorful essential fatty acid-N-3 oleic acid, in which two carbohydrates, EPA and DHA, are really critical to the growth and development of the central nervous system and the brain, but they are only useful during pregnancy or during the growth and development of babies, and are not harmful to the adult brain. In other words, even if adults eat a lot of fish every day, they will not have a high IQ.
Eating walnuts to "brain"? Don't be a feudal superstition rumor: folk customs also have the idea of "supplementing shape with shape". Because walnut kernel looks like brain, it has become a brain-nourishing food for many people.
Fact: Ruan Guangfeng indicated, "To say that walnut kernel' supplements brain' is endangered by the consciousness of' supplementing shape with shape' to a great extent. From the perspective of contemporary pharmacology, although walnut kernel with polyunsaturated fat is beneficial to the brain, it does not mean that it can' replenish the brain'. " Ruan Guangfeng suggested that all the normal operation of the brain can be ensured by diversified diet and balanced nutrients in all directions, and it is not necessary to blindly follow the feudal superstition of "brain-nourishing" ingredients.
Eating fish is smarter? It is also said that eating more fish meat and drinking more fish head soup can make people smarter. Is that really the case?
Fish does contain rich and colorful essential fatty acids-N-3 oleic acid, among which EPA and DHA are well-known. These two carbohydrates are critical to the growth and development of the central nervous system and brain. It is found that if the pregnant mother does not take enough EPA and DHA during pregnancy or the baby's growth and development, it will probably hinder the growth and development of the brain and central nervous system. Therefore, generally speaking, the authorities of physical and mental health all over the world strongly recommend that everyone should eat seafood two or three times a week, including fish, shrimps and shellfish, especially pregnant mothers and babies.
However, EPA and DHA are harmless to the adult brain. In other words, adults, even if you eat a lot of fish every day, it is not easy for you to suddenly have Newton-like intelligence.
Is there a brain-nourishing ingredient? Speaking of this, everyone will undoubtedly ask, then, how to eat to make up the brain? Are there any real "brain-nourishing" ingredients?
In fact, everyone's brain is a complicated central area, and its necessary nutrients are not single, but various.
First of all, the brain is mainly composed of protein, so this component is indispensable. However, after people grow and develop to a certain level, the total number of brain nerves will inevitably decrease, and no amount of ingredients can make up for it.
Secondly, everyone's brain especially likes glucose water. Glucose water is the most basic way for the brain to use kinetic energy. With plenty of glucose water, the brain is golden enough to run.
In addition, unsaturated fatty acids and zinc can also harm the brain, especially calcium deficiency can harm people's memory ability. However, the more zinc is not, the higher the memory ability will be, and too much zinc will be poisoned. Zinc is very rich in seafood such as oysters. Unsaturated fatty acids are the raw materials of memory-related neurotransmitter choline, which are more colorful in egg yolk and soybean.
The brain must also have vitamins. Vitamin B 1 is the most important vitamin, because it has the least storage in the body, and it is likely to be harmful to work efficiency if it is not enough for a few days. Others, such as fat-soluble vitamins and nutrients, are not nutrients whose actual effects can be seen in a few days. Therefore, it is necessary to eat some coarse cereals, sweet potatoes and legumes to supplement B vitamins.
Therefore, everyone's brain must have a variety of nutrients, but it is too divorced from reality to rely on one kind of food to replenish the brain, and eating a certain kind of food can't have the effect of nourishing the brain.
In addition, scientific research will continue to tell you a sad objective fact: most people's IQ will reach its peak at the age of 20 to 30, and it will be difficult to improve it in the future. It is only wishful thinking to improve their memory according to what they eat.
