Walnuts are one of the four major dried nuts, but can they really boost brain power? There is a right way to eat them each day

Walnuts, together with almonds, cashews and hazelnuts, are known as the world-famous “four major dried nuts”. Walnuts are nutritious and are one of the nuts people eat most often. So, can walnuts really boost brain power? How many walnuts is it best to eat a day? What are the dietary restrictions for walnuts? What is the market price of walnuts per jin? Let's take a look together.

1. Can walnuts really boost brain power?

Because their shape resembles the human brain, walnuts have long been praised as an “excellent brain-boosting food”, but can walnuts really boost brain power?

Among the substances related to human brain development, DHA is considered to be related to human brain development. DHA is the abbreviation of DocosahexaenicAcid, commonly known as “brain gold”, with the full Chinese name docosahexaenoic acid, but research has found that walnuts contain almost no DHA and have no direct DHA-supplementing function. However, walnuts contain a large amount of α-linolenic acid, which is a substance that can supplement DHA.

Therefore, walnuts cannot boost brain power; rather, it should be said that walnuts contain nutrients the brain needs, rather than “boosting the brain”. Moreover, among many foods, there are quite a few foods rich in α-linolenic acid and DHA, and walnuts are not a necessity.

Although walnuts cannot directly boost brain power, they are an excellent food for dietary therapy and are rich in nutritional value. Walnuts contain phospholipids, and this substance has a very good effect on the development of brain nerves. Walnut oil contains unsaturated fatty acids, which can effectively prevent and treat arteriosclerosis. Walnuts also contain various trace elements such as zinc, manganese and chromium. Walnut kernels also have the effect of relieving cough and calming asthma, so eating walnut kernels also improves chronic bronchitis and asthma.

2. How many walnuts is it best to eat a day?

As one of the four major nuts, walnuts themselves have a very high fat content. If too much is consumed without being used up, a large amount of fat will accumulate, adding burden to the body.

Experts suggest that, generally speaking, the daily intake of walnut kernels should be about 20-40 grams, roughly equivalent to 4-5 walnuts. While eating walnuts, other fat intake should be reduced and exercise increased to avoid excessive fat accumulation.

In addition, from a nutritional point of view, walnuts should not be eaten in excess at one time. The correct way to eat them is in appropriate amounts over the long term, so that the health benefits of walnuts can be better brought into play.

3. What are the dietary restrictions for walnuts?

1. Do not eat large amounts

Walnuts contain very high protein and fat, and eating too many at one time will cause indigestion. Nutrition experts suggest that it is best not to eat more than 4 walnuts a day, and while eating walnuts, other fat intake should be reduced and exercise increased to avoid excessive fat accumulation and excessive calories.

2. People with excess internal heat or diarrhea should not eat them

Walnuts are warm in nature and high in oil content, and eating too many will cause internal heat and phlegm. People with conditions such as yin deficiency with hyperactive fire, phlegm-heat cough, phlegm-dampness, and diarrhea should not eat many walnuts.
