Essential fatty acids are essential for maintaining the functions of various tissues, and when lacking, they will cause a series of symptoms, including growth retardation, abnormal skin scales, infertility, mental retardation and so on. As an essential fatty acid, DHA plays a more significant role in enhancing memory and thinking and improving intelligence. For example, 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 women lack DHA in their diet during pregnancy, it may lead to fetal blindness.

[DHA-rich food]

Deep-sea fish: tuna, tuna (yellowfin tuna), salmon (salmon), whales, seals, herring, hairscales, salmon (Atlantic salmon), trout, cod, saury, herring, tuna, sardines, eels,

The DHA content in marine fish and shellfish fat is 2.5- 100 times higher than that of terrestrial animals and plants.

Freshwater fish: Carassius auratus, Monopterus albus and fish eggs.

In addition, fish and shrimp, lean meat, eggs, milk, tofu, soybean milk, etc. These foods are not only rich in high-quality protein, but also rich in calcium, iron, vitamins A, B 2 and D, especially deep-sea fish. This kind of food is rich in DHA, which can improve brain function and enhance memory. Eating fish regularly, especially marine fish, can get enough DHA.

Note: Soybeans, soybeans, milk fat, vegetables, fruits, algae and other foods do not contain DHA.

DHA is mainly concentrated in fish oil.

▲ Fish with high DHA content in fish oil:

Frog fish, rainbow trout, bighead carp, bonito, tamarind, Fish, fat-eyed herring, crucian carp, tuna (red meat), cuttlefish, etc.

ARA, also called arachidonic acid, is also a polyunsaturated fatty acid, which is an essential nutrient for baby's physical development. In adults, linoleic acid can be transformed from essential fatty acid, but it is not an essential fatty acid. However, in infancy, the baby's ability to synthesize ARA is low, so providing certain ARA in food will be more conducive to the baby's physical development. Foods containing polyunsaturated fatty acids include breast milk, soybean oil, sunflower oil, walnut oil, safflower oil, soybean salad oil and nuts.
