Population epidemiological studies have found that people with high DHA content in their bodies have strong psychological endurance and high intellectual development index. DHA can also prevent myopia and improve vision. If DHA is lacking in women's diet during pregnancy, it may lead to fetal blindness and a series of symptoms such as growth retardation, abnormal skin scales, infertility and mental retardation.

The content of DHA in colostrum is particularly rich. However, the content of DHA in mother's milk depends on the food structure of three meals. Japanese mothers eat more fish, and the DHA content in milk is as high as 22%, ranking first in the world; Followed by Australia, about10%; The United States is the lowest, only 7%.

2. Formula milk powder.

Refers to formula milk powder with DHA added.

3. Fish.

Fish with high DHA content include tuna, bonito, salmon, mackerel, sardine, bamboo pod fish, swordfish, tuna, yellow croaker, saury, eel, hairtail, crucian carp, etc. The DHA content in each100g fish can reach more than1000mg. As far as a certain kind of fish is concerned, the part with high DHA content is the first to promote orbital fat, followed by fish oil.

4. Dried fruits.

Such as walnuts, almonds, peanuts, sesame seeds, etc., which contain? Linolenic acid can be converted into DHA in human body.

5. Algae.

6. DHA products.

At present, there are two kinds on the market: one is extracted from deep-sea fish oil, and the other is extracted from algae. The former is derived from fish fat, but it has at least three major defects:

(1) The content of EPA (eicosapentaenoic acid) in fish oil is too high, which can make the proportion of DHA too low, which is quite different from breast milk and does not meet the physiological needs of children;

(2) Although the DHA content in fish oil is relatively high, it does not contain another unsaturated fatty acid, AA (arachidonic acid), which plays an important role in brain development, and too much EPA will also inhibit the production of AA in children;

(3) Fish are polluted by heavy metals such as mercury and lead or harmful substances such as arsenic to varying degrees, so the safety is low.

In contrast, the advantages of algae are outstanding. DHA algae oil is a pure plant DHA raw material, which is extracted from artificially cultivated marine microalgae and is the purest and safest DHA source in the world at present. It is particularly worth mentioning that the DHA concentration of DHA algae oil is much higher than that of fish oil extract, and its purity is high (in terms of content, DHA of DHA algae oil? 35g/ 100g, and the content of fish oil DHA is 3.6- 12.5g/ 100g). It has strong stability, is not easy to be oxidized, is odorless and tasteless, and is especially suitable for fetuses and infants.
