Old people think that eating walnuts can replenish the brain. Can walnuts really replenish the brain?

When it comes to nuts, it is necessary to say walnuts. Walnuts are delicious and nutritious, and they are deeply loved by people.

Not only that, the elders taught us from an early age that if we eat walnuts to replenish our brains, we should eat more, so that we can become smarter and get into a good university.

Go to the peak of life!

After eating walnuts for so many years, I suddenly have a question, can eating walnuts really replenish the brain? In fact, the human brain is very complicated.

Different age groups have different connotations of brain tonic, which cannot be explained clearly in one or two sentences. Today, we will take you to find out.

Can minors become smart by eating walnuts?

In adolescence, brain tonic refers to the development of brain cells. The development of brain cells is inseparable from essential fatty acids. Essential fatty acids refer to fatty acids that the human body needs, but cannot be synthesized by itself and must be ingested from food.

Two thirds of nutrients in walnut kernel are fat, and linoleic acid and α -linolenic acid are essential fatty acids.

What happens when you lack essential fatty acids for a long time? It will lead to the "assembly" of the cranial nerve system, and the quality will decline due to the lack of raw materials. Eating walnuts can prevent this from happening to some extent.

Can adults eat walnuts to replenish their brains?

Youth supplements the brain mainly to supplement the nutrition of brain tissue. That is, the reasonable supply of essential fatty acids is beneficial to the nutritional maintenance of brain tissue. Obviously, eating walnuts at this time will also help.

Middle-aged brain tonic is mainly to prevent brain tissue aging. The content of unsaturated fatty acids in walnut fat can reach 90%, and these unsaturated fatty acids have oxidation resistance. There is a saying that oxidation is the mechanism of aging, and anti-oxidation helps to resist aging, including the aging of brain cells.

The content of protein in walnut is 18%, among which glutamic acid and arginine rank in the top two, which can promote brain cell respiration and blood ammonia metabolism respectively, and also can resist oxidation.

The elderly should also replenish their brains, the main purpose of which is to prevent and alleviate degenerative brain diseases. These include:

Antioxidant. Unsaturated fatty acids in walnut fat and glutamic acid and arginine in walnut protein have antioxidant effects, which can avoid the occurrence of brain degenerative diseases to some extent.

Conducive to the prevention of Parkinson's disease. Walnut extract has neuroprotective effect in Parkinson's disease model and may have the potential to prevent or treat Parkinson's disease.

To sum up, eating walnuts has certain benefits to the brain, but its effect is limited. It doesn't mean that eating walnuts will make you smart, nor should it be regarded as a decisive factor in becoming smart!

What are the more effective ways to replenish the brain?

Balanced nutrition. Ensure the intake of essential fatty acids and essential amino acids. Appropriate cooked food, nuts, fresh fruits and vegetables, etc. To ensure the growth and development of brain cells have enough raw materials to supply.

Have a reasonable rest. Excessive mental work will make brain cells consume too much energy and even induce their apoptosis. Although there are a lot of brain cells in human brain, because brain cells are non-renewable, don't let the brain "overwork".

Necessary training. According to different age groups, with the necessary intellectual training, that is, our learning activities, it is helpful to the development of brain cells and the establishment of connections between nerve cells.

What are the benefits of eating walnuts?

Eating walnuts in moderation is helpful to prevent cardiovascular and cerebrovascular diseases.

Linoleic acid and linolenic acid contained in walnuts are essential substances for the synthesis of prostaglandin E(PGE) in vivo. PGE can prevent thrombosis, lower blood pressure and prevent platelet aggregation, thus preventing cardiovascular and cerebrovascular diseases.

In a prospective study of 7480 people aged 40-85 with cardiovascular risk, linoleic acid can reduce the risk of ischemic stroke.

α -linolenic acid can promote blood lipid transport and reduce blood lipid.

In addition, walnut polyphenols in walnut inner seed coat can inhibit the oxidation of low density lipoprotein and have the potential of anti-atherosclerosis.

What are the precautions for eating walnuts?

Eat fresh walnuts and walnuts with short storage time and reasonable storage conditions. Don't eat moldy walnuts.

Walnut is rich in nutrition and easy to provoke mold. Once moldy, it will not only taste worse, but also produce mycotoxin, which is harmful to the body.

Walnuts are high in fat and energy and are not recommended for obese people. In addition, fat digestion requires bile emulsification, and patients with liver disease should not eat more walnuts. Patients with gallstones should not eat it, so as not to stimulate the gallbladder to contract violently. Young children should not eat more because the digestive system is not yet mature.

Eating too much walnuts will cause a loss of appetite and a strong sense of fullness. It is recommended to control the daily and single consumption to avoid affecting the dinner.

On the whole.

Eating walnuts is really good for the brain.

Good for health.

But it doesn't mean it can make people smart.

And its function is limited.

Don't deify it
