The applications of dha in food are as follows:

1. Fish: Fish with high DHA content include tuna, bonito, salmon, mackerel, sardines, and horse mackerel , swordfish, tuna, croaker, saury, eel, hairtail, crucian carp, etc.

2. Dried fruits: such as walnuts, almonds, peanuts, sesame, etc. The alpha-linolenic acid contained in it can be converted into DHA in the human body. There are also many DHA products on the market.

3. Breast milk and colostrum are particularly rich in DHA. However, the DHA content in mother's milk depends on the food structure of the three meals.

4. Sea cucumber. Sea cucumbers are rich in nutrients, one of which is DHA. During pregnancy, pregnant women need to consume DHA to support fetal development. Therefore, many pregnant mothers consume sea cucumbers as a supplement. As a green and natural marine tonic, sea cucumbers live up to expectations.

5. Formula milk powder. Refers to formula milk powder added with DHA. The so-called added DHA content of milk powder is very small.

6. Algae. Algae oil is extracted directly from marine algae. It has high content, has not been passed through the food chain, has no heavy metal pollution, does not contain EPA, and is safe and easy to absorb.

Main functions

1. Promote fetal brain development

During pregnancy, DHA optimizes fetal brain pyramids Composition of phospholipids in cells. Especially after the fetus is 5 months old, if the fetus' hearing, vision and touch are artificially stimulated, the neurons in the sensory center of the fetal cerebral cortex will grow more dendrites, which requires the mother to provide more DHA to the fetus at the same time. . ?

2. Promote the maturation of retinal light-sensitive cells

DHA not only has an important impact on fetal brain development, but also plays an important role in the maturation of retinal light-sensitive cells. Pregnant women can consume DHA during pregnancy and then transport it to the fetal brain and retina to increase the maturity of nerve cells.

3. Promote brain cell development

In the cerebral cortex, DHA is not only the main component of nerve conduction cells, but also the main component of cell membrane formation. Most DHA is not digested by gastric juices, but enters directly into the bloodstream and is absorbed by organs such as the liver or brain. Linseed oleic acid is not absorbed, mainly because DHA can enter brain cells through the blood-brain barrier, while EPA and linoleic acid cannot be absorbed by the brain through the blood-brain barrier.

4. Reduce postpartum depression

Research shows that 50-75% of women in my country experience a period of postpartum depression after the birth of their child, and 10%-15% of new mothers will become depressed. It's so intense that it's termed "postpartum depression." Postpartum depression not only seriously threatens the physical health of the mother, but also affects the baby's development, causing the baby to develop emotional disorders and abnormal behavior. Adequate DHA can reduce the occurrence of postpartum depression.

The "2015 Expert Knowledge on DHA Supplementation for Chinese Pregnant Women and Infants" pointed out that although DHA is a non-essential fatty acid and can be synthesized from α-linolenic acid, it has a low conversion rate and is harmful to Fetal brain development and retinal development are crucial, so for pregnant and lactating women, DHA can also be regarded as a conditional "essential fatty acid".

Therefore, there are very strict restrictions on adding DHA and AA to infant milk powder, and the Ministry of Health has clear regulations on this. It is best for consumers to distinguish clearly when purchasing and not to buy blindly.
