Final answer:
Omega-3 fatty acids, especially DHA, are beneficial for the brain and eye development of infants, as well as reducing the risk of heart disease by impacting blood pressure, triglycerides, and inflammation.
Step-by-step explanation:
Omega-3 fatty acids, namely alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA), play a significant role in human health. They are particularly beneficial for infants, as they contribute to normal growth and development of the brain and eyes. While omega-3 fatty acids like EPA and DHA are not considered essential since they can be synthesized from ALA, the conversion rate in the body is quite limited. Therefore, dietary intake of omega-3s is important. Sources such as fish, shellfish, and human breast milk are rich in EPA and DHA. These polyunsaturated fatty acids not only support brain function and growth but also provide health benefits like reducing blood triglycerides and blood pressure, preventing blood clot formation, and reducing inflammation which may potentially reduce the risk of heart disease and certain cancers.
