The correct answer is: the nervous system, brain, and eyes.
Explanation:
Arachidonic acid (ARA) and docosahexaenoic acid (DHA) are long-chain polyunsaturated fatty acids that have great nutritional value, as they are omega-6 and omega-3 fatty acids, respectively, meaning they are essential fats that cannot be produced by the body and, therefore, need to be part of the diet.
The consumption of ARA and DHA has been directly linked to the development of the brain and the retina, and the inclusion of these fatty acids in the nutrition of infants has been proven to be extremely beneficial to their growth.
Besides their functions in the development of the nervous system and the eyes, ARA and DHA play a role in maintaining a healthy immune system and preventing cardiovascular conditions.
