Food sources of DHA?

Food sources of DHA

1. The mother's milk. Colostrum is especially rich in DHA. However, the amount of DHA in a mother's milk depends on the composition of her meals. Japanese mothers eat more fish, and their milk contains 22 percent DHA, ranking first in the world. Australia followed with about 10%. The United States has the lowest, at 7 percent.

2. Formula. Formula milk powder with added DHA.

3. The fish. Fish with high DHA content include tuna, bonito, salmon, mackerel, sardines, bamboos, swordfish, tuna, yellow croaker, autumn knife fish, eel, hairtail, and crucian carp. DHA content per 100 grams of fish can reach more than 1,000 milligrams. In the case of a particular type of fish, the highest DHA content is the eye socket fat, followed by fish oil.

4. Dried fruits. Such as walnut, almond, peanut, sesame and so on. The α-linolenic acid contained in it can be converted into DHA in the body.

5. The algae.

6. DHA products. There are two on the market: one derived from deep-sea fish oil and the other from algae. The former is derived from fish fat, but has at least three major drawbacks:

⑴ The content of EPA(eicosapentaenoic acid) in fish oil is too high, which can make the proportion of DHA too low, which is different from breast milk and does not meet the physiological needs of children;

(2) Although the content of DHA in fish oil is relatively high, it does not contain another unsaturated fatty acid -- AA(arachidonic acid), which is important for brain development, and too much EPA will inhibit the generation of AA in children's bodies;

(3) Fish are polluted by mercury, lead and other heavy metals or arsenic to varying degrees, and their safety is low. In contrast, algae have a prominent advantage. DHA algal oil is a pure plant DHA raw material, extracted from cultured Marine microalgae, which is not passed through the food chain. It is currently the purest and safest source of DHA in the world.

In particular, it is worth mentioning that the DHA concentration of DHA algal oil is much higher than that of fish oil extract, and the purity is high (content, DHA algal oil DHA≥35g/100g, fish oil DHA content is 3.6-12.5G /100g), strong stability, not easy to be oxidized, and odorless, tasteless, especially suitable for fetus, infant.
