1, breast milk. 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. Japan is a coastal country that eats more fish, and the dha content in mother's milk ranks first in the world, reaching 22%.

2. Fish. It contains a lot of protein and calcium, especially saturated fatty acids, which can decompose cholesterol and make cerebral vessels unobstructed. It is suggested that mother can eat 1~2 fish within a week to absorb enough dha.

3. Dried fruits. Such as walnuts, almonds, peanuts, sesame seeds, etc. The α -linolenic acid contained in it can be converted into dha in human body.

4, fisheye. In particular, the tuna eye of the family Ceratopogonidae is rich in unsaturated fatty acids such as docosahexaenoic acid (dha) and eicosapentaenoic acid (EPA). This natural substance can enhance the brain's memory and thinking ability, which is of great benefit to prevent memory decline, cholesterol increase, hypertension and other diseases. The main source of dha is marine fish, but it is not only found in deep-sea fish, but also in freshwater fish.

5. dha products. The concentration of dha extracted from algae is much higher than that of fish oil extract, and its purity is high. In terms of content, the dha content of dha algae oil is more than or equal to 35g/100g, and the DHA content of fish oil is 3.6- 12.5g/ 100g. It has strong stability, is not easy to be oxidized, and is odorless and tasteless. It is especially suitable for fetus and fetus.
