Introduction
Omega-3 and DHA are essential nutrients for fetal development. During pregnancy, providing adequate Omega-3 and DHA can support the development of the baby's brain, eyes, and cardiovascular system. However, choosing the right food sources and supplements requires careful consideration.
The Role of DHA
DHA (Docosahexaenoic acid) is an important Omega-3 fatty acid, making up about 10% of the total fat in the brain. DHA plays a crucial role in the development of the brain, eyes, and cardiovascular system of the fetus. According to the World Health Organization (WHO), DHA may also help reduce the risk of cardiovascular disease and hypertension in the mother.
