PREGNANCY NUTRITION: THE ESSENTIALS

Posted on

A baby developing inside the womb receives all its nutrition from its mother. Therefore, it is importantthat expectant mothers have the best diet possible during pregnancy, to help their babies grow and thrive. Our NHD guest blogger, Heather Frost AfN, takes us through the most important aspects of nutrition for conception and pregnancy.

pregnancy-&-nutritionA woman’s body changes and adapts during pregnancy to ensure their unborn child gets the quantity of food it needs, meaning energy intakes do not need to rise. Any excess energy only leads to weight gain which can harm both the mother and baby’s health.1 To keep hunger at bay and for healthy foetal growth and development, mothers should consume two to three servings of protein per day from various sources such as eggs, beans, fish, meat, tofu, nuts and quorn.2

THE IMPORTANCE OF FIBRE

Pregnancy slows down the digestive system due to increased levels of progesterone, which increases the risk of constipation.3 Fibre-rich foods, such as bran, wholemeal bread, brown pasta, vegetables, beans and pulses, increase the frequency of defecation and lead to softer stools, keeping things moving along steadily.

8 ESSENTIAL VITAMINS AND MINERALS

1 Folic acid
One of the most important dietary components required during pregnancy is folic acid (folate) and is found in green leafy vegetables such as kale, spinach and broccoli, beans and pulses, yeast extracts and brown rice. Expectant mothers should consume 400ug of folic acid daily for at least three months before conception and throughout the first trimester of pregnancy to prevent neural tube defects, such as spina bifida.4

2 Vitamin B12
Vitamin B12 helps the body use folic acid; therefore, expectant mothers should also consume a minimum of 1.5ug per day from various sources such as milk, egg, cheese, fish, beef and fortified cereal.5

3 Choline
Choline is important for brain development (memory and learning) and for neural tube formation.6 Expectant mothers should consume 480mg per day of choline from sources such as vegetables, fruits, wholegrains, dairy products, fish, beef, poultry and eggs.

4 Iron
Expectant mothers should consume 14.8mg of iron daily to avoid preterm delivery, foetal growth restriction and preeclampsia.7 Iron is found in a variety of foods such as lean red meats, fortified breakfast cereals, pulses (baked beans, chickpeas and lentils), eggs, dried fruits, dark green leafy vegetables, nuts and seeds.

5 Iodine
Iodine is important for the production of thyroid hormones, which are essential for foetal brain development. Mild to moderate iodine deficiency is associated with reduced cognitive scores; therefore, pregnant women are required to consume 250ug per day.8

6 Omega-3
Omega-3 fatty acids (DHA and EPA) are essential for normal foetal central nervous system, birth weight and growth.9 Expectant mothers must consume 450mg daily from sources such as oily fish (shrimp, salmon, pollock, catfish, scallops and sardines), vegetable oils and/or supplements.

7 Calcium
1000mg calcium per day is required during pregnancy to meet both maternal and foetal bone requirements. Consume calcium-rich foods three times a day such as milk, yoghurt, cheese, fish, tofu, pulses and almonds.10

8 Vitamin D

Vitamin D deficiency can lead to preeclampsia, gestational diabetes, urine infections, caesarean deliveries and poor infant long-term bone health.11 Vitamin D is produced by the body from exposure to sunlight; however, it is important to consume 10ug vitamin D daily from foods such as fish-liver oils, fatty fish, fortified breakfast cereals, lean red meats, mushrooms and egg yolks.

In summary, expectant mothers should eat a variety of foods every day to get the right balance of nutrients in order to meet their own needs and those of their developing baby.
