SCI 228 WEEK 7 ILAB, PRENATAL LIFECYCLE AND
NUTRITION
Prenatal is define by Google as “before birth” or during pregnancy. There is no specific age for this
lifecycle, as women can birth children from early teens to their 50s. Nutrition is important prior to
conception, during pregnancy and after the birth of an infant. Pregnancies, when full-term usually last 37-
42 weeks, from the first day of the last menstrual cycle, to the day the baby is born. This time period is
divided in to three trimesters, with each one lasting between 12-14 weeks (Stickler, 2014).
By the end of the first trimester, Stickler (2014) notes that a baby will have developed all of its organs.
The mother should aim to consume the same amount of calories as before, ensuring an adequate supply of
folic acid which can help prevent neural tube defects. The number of calories consumed daily should
increase, according to Pruitt et al (2010), by 350-400kcal during the second and third trimesters. They
point out that it is important to eat nutrient-dense foods, as macronutrient requirements increase by 50%
during this time (pg. 706).
Nutrition
During pregnancy, there is an increased need by the mother for macronutrients. The extra macronutrients
are needed as the blood volume of the mother has increased. They are also needed to support the growth
of the placenta, uterus, and the fetus (Pruitt et al, 2010, pg.707), as well as providing the mother with
adequate nutrients to ensure her own health is maintained. Macronutrients are essential during this stage
of the lifecycle as they “provide necessary energy for building tissue. They are also the building blocks
for the physical form and structure of the fetus, as well as for other pregnancy-associated” (pg.706).
Below are the types of micronutrients that are important during pregnancy and the recommended daily
intake:
Protein (71g): Required for cell building for both mother and baby.
Carbohydrates (175g): Provides energy to support a growing baby. Carbohydrates contain many other
nutrients including fiber.
Fat (65g): Essential for the building of new cells and tissue. Source of fuel for a newborn baby.
Folate (600ug): Required for cell division, the formation and closure of the neural tube as well as the
spinal cord and the brain. A lack of folate during pregnancy can cause macrocytic anemia and is also
linked with a “low birth weight, preterm delivery, and failure of the fetus to grow properly” (Pruitt et al,
pg. 707). Because folate is extremely important to a baby’s development, women are advised to take a
daily folic acid supplement to ensure their needs are met.
Vitamin B12 (2.6ug): Important for the development of the nervous system. It is possible that children
born to mothers who had a vitamin B12 deficiency during pregnancy, are at risk of insulin resistance which
can lead to obesity (Richards, n.d.).
Vitamin C (85ug): Needed for the production of collagen. The possibility of developing preeclampsia,
having a preterm birth and premature rupture of placental membranes is higher in mothers who have a
vitamin C deficiency (Puitt et al, pg.708).
