According to scientific research, humans eat too much sweets can affect vision. However, for a particular group of expectant mothers, eating too much sweets will not only affect their vision but also affect the fetal vision. At the same time, if you want your child to have good vision when you are born, the diet during pregnancy is very important.

Nowadays, due to the continuous improvement of living standards, people's diet structure is getting more and more refined, and more and more fine grains are ingested, and more sugar is added. It is well known that excessive intake of sugar in the body is detrimental to the development of the eye.

Excessive intake of sugar may cause accumulation of sugar in the body, and when sugar is metabolized in the body, it requires a lot of vitamins, so the vitamin will be insufficient due to excessive consumption. Eye cell development also requires a large amount of vitamins to participate.

This is especially true for pregnant women. If too much sugar is consumed, it will lead to abnormal crystal development environment, and the axial development will be too fast, which will accelerate the occurrence of myopia. Animal experiments have shown that letting experimental animals ingest polysaccharides has an effect on their vision.

So, what do pregnant women eat for the baby's vision?

[Four nutrients affect fetal vision]

I. Alpha linolenic acid

We often eat nuts such as walnuts, deep sea fish such as grouper, squid, tuna, or fish oil are rich in alpha linolenic acid.

Here, we must point out the importance of alpha linolenic acid for fetal eye development. Alpha linolenic acid is an important substance that constitutes brain cells and retinal cells. It promotes the development of fetal and neonatal brain cells, promotes the production of rhodopsin in the retina, improves the intelligence and vision of the fetus and newborn, and reduces the fetal and neonatal neural tubes. Malformations and the incidence of various birth defects.

Second, vitamin A

There are two types of foods rich in vitamin A: one is vitamin A, which is a variety of carotene, which is found in plant foods, such as green leafy vegetables, yellow vegetables and fruits, and spinach, wolfberry, Pea seedlings, red sweet potatoes, carrots, green peppers, pumpkins, etc.; the other is vitamin A from animal foods, which are vitamin A that can be directly used by the human body, mainly in animal liver, milk and dairy products. (not skimmed milk) and eggs.

Vitamin A is an important raw material for the synthesis of rhodopsin, which is a photosensitive substance found in the retina. Vitamin A plays a very important role in maintaining the normal vision of the human body, especially in the low light. In the absence of vitamin A, the ability of the eye to experience weak light will decrease, and in the weak light, the object cannot be seen at all.

Third, taurine

Among all foods, fish and shellfish are the most abundant in taurine. Regular consumption of such foods can supplement taurine and stay healthy.

There is a large amount of taurine in the human retina, which can improve visual function and promote the development of the retina. Taurine can also protect the retina, which is beneficial to the development of visual receptors and improves visual function. Studies have shown that the cornea of the eye has self-repairing ability, and taurine can strengthen the self-repairing ability of the cornea to fight against eye diseases. Thus, taurine is also very important for preventing eye diseases and protecting eye health.

 In infants, the ability to synthesize taurine and renal tubular cells to reabsorb taurine is poor. If there is no external supply, taurine deficiency may occur. Preterm infants lack a reserve of taurine and are more likely to be deficient. Nutritionists recommend supplementing taurine to the fetus and infant through the mother. It is very necessary for pregnant mothers and new mothers to add taurine as soon as possible.

Fourth, vitamin B

Vitamin B1 is widely found in natural foods, and is rich in animal internal organs (liver, heart and kidney), meat, beans, peanuts and grains, fruits and nuts. The content of fruits, vegetables, eggs and milk is low. Animal viscera is rich in vitamin B2, especially in the liver. Other animal foods such as pork, eggs, and squid and crab in aquatic products also contain more vitamin B2. Bacterial algae foods such as mushrooms, kelp and seaweed in plant foods contain more vitamin B2.

Vitamin B1 and vitamin B2 are one of the nutritional sources of optic nerves. If the vitamin B1 is insufficient, the eyes are prone to fatigue. If vitamin B2 is insufficient, it is easy to cause keratitis.

Suggestion: Pregnant mothers need to eat 50 to 100 grams of these internal organs every day to meet the needs of pregnant mothers for one day of vitamin B2. In addition, do not eat too fine and over-picked rice, cereals are the main source of vitamin B1, but because vitamin B1 is more present in bran and germ, such as rice milling can cause a large loss of vitamin B1.
