Maternal nutrition plays a critical role in the development and growth of the foetus during pregnancy. Extensive research has been conducted to understand the intricate relationship between maternal nutrition and foetal outcomes, leading to the development of evidence-based recommendations to optimize maternal nutrition. This article provides an overview of current research findings and recommendations regarding maternal nutrition and its impact on foetal development. Adequate maternal nutrition is essential for optimal foetal growth and development. During pregnancy, the mother's body undergoes various physiological changes to support the developing foetus. A balanced diet that includes a variety of nutrient-rich foods is crucial to provide the necessary building blocks for foetal tissue formation and organ development. Insufficient intake of key nutrients during pregnancy has been associated with an increased risk of adverse foetal outcomes, such as low birth weight, preterm birth, and developmental abnormalities [1].

Several nutrients have been identified as critical for foetal development. Folic acid, a B vitamin, is of particular importance. It plays a vital role in the formation of the neural tube, which develops into the baby's brain and spinal cord. Adequate folic acid intake before and during early pregnancy has been shown to significantly reduce the risk of neural tube defects, such as spine bifida. To ensure sufficient folic acid intake, women of childbearing age are advised to consume foods rich in foliate, such as leafy green vegetables, citrus fruits, and fortified cereals, or take a daily folic acid supplement [2].

Iron is another essential nutrient for maternal and foetal health. Iron is necessary for the production of red blood cells and for oxygen transport throughout the body. Inadequate iron intake during pregnancy can lead to maternal anaemia, impairing oxygen delivery to the foetus and hindering foetal growth. Pregnant women are recommended to consume ironrich foods, such as lean meats, poultry, fish, legumes, and fortified grains, and may require iron supplements if their iron levels are low [3].

Omega-3 fatty acids are important for foetal brain and visual development. These essential fatty acids are found in fish, particularly fatty fish like salmon and sardines, as well as in certain plant sources like walnuts and flaxseeds. Studies have suggested that omega-3 fatty acids may contribute to improved cognitive development and reduced risk of certain developmental conditions in children. However, pregnant women should be cautious about consuming fish that may be high in mercury, which can be harmful to the developing foetus. It is recommended to choose fish with lower mercury levels and to limit consumption of fish known to be high in mercury [4].

In addition to specific nutrient intake, the overall quality of the maternal diet has been found to influence foetal development. A diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats has been associated with better pregnancy outcomes. These nutrient-dense foods provide essential vitamins, minerals, antioxidants, and fibre, supporting the growth and development of the foetus. On the other hand, diets high in processed foods, added sugars, and unhealthy fats may increase the risk of gestational diabetes, excessive gestational weight gain, and complications during childbirth.

Maternal weight and body mass index (BMI) also play a crucial role in foetal development. Maternal obesity has been associated with an increased risk of gestational diabetes, preeclampsia, birth defects, and complications during labour and delivery. Overweight and obesity in pregnancy can have long-term effects on the child's health as well. Therefore, maintaining a healthy weight before and during pregnancy is important for both maternal and foetal well-being [5].


Maternal nutrition is a key determinant of foetal development and plays a vital role in ensuring optimal pregnancy outcomes. Adequate intake of essential nutrients, such as folic acid, iron, and omega-3 fatty acids, along with a well-balanced diet, is crucial for supporting foetal growth and reducing the risk of adverse outcomes. Women planning for pregnancy or who are already pregnant should consult healthcare professionals for personalized dietary recommendations and ensure that their nutritional needs are met for the healthy development of their baby.
