Docosahexaenoic acid (DHA) and Arachidonic acid (AA)

Brain is the center of intelligence, skill, sensitivity, and also mental development of human. Even, chemically, about 60% of human brain comprised of lipids. From the amount of the lipids, DHA (Docosahexanoic acid) and AA ( Arachidonic acid) are the dominant components that composing nerve cells and baby’s brain. So, it is true that the function of brain will be much affected by the composing lipids. Therefore, the development of human brain is also affected by the kind of food, especially DHA and AA.

The development of human brain was started when fetus still in the womb, so that the fetus’ needs for DHA and AA had been started. In that time, the necessity of omega-3 fatty acid was acquired from mother’s blood that flowing through placenta. The continuously delivering of DHA to the fetus is needed until the third trimester of pregnancy. Even, the DHA needs in the small brain and in the cerebrum increase by three fold during the last trimester. These essential fatty acids are used to build brain nerves and also retina.

In The American Journal of Clinical Nutrition (71:1) Suppl, 327s-30s noted that the omega fatty acids are very important for baby’s development. Moreover, lacking of omega-3 fatty acids is closely related to the disturbance of delivering message and stimulation by the nerve cells. It can cause these following things:

  1. Decrease the remembering memory.

  2. The vision getting bad.

  3. Decrease the immune system.

American Journal of Clinical Nutrition February 2003 edition also noted that lacking of DHA in the brain and retina could affect these followings:
  1. Disturbance of vision ability.

  2. Disturbance of learning activity.

  3. Disturbance of behavior.

  4. Disturbance of neurotransmitter metabolism.
