NUTRITION DURING PREGNANCY & LACTATION
PREGNANCY
BONE DEVELOPMENT
CALCIUM AND PHOSPHORUS
1000mg per day
Source
calcium
: - milk, cheese yoghurt, dark and green leafy veggies
High phosphorus intake interfere with calcium absorption
Sources
phosphorus
: red meat and poultry, dried milk and milk products, wheat germ, yeast, grains, hard cheeses, canned fish, nuts
VITAMIN D
Vital role in calcium absorption and utilization
Deficiency- ricket in fetus, -osteomalacia in mother
1.4 μg/day
Sources: Catfish, Salmon, Mackerel, Tuna
MAGNESIUM
Function: bone formation
activation of vitamin D and in the release of parathyroid hormone that acts on the kidney and bone to raise blood calcium’
400mg/day
Sources: dairy products, breads and cereals, legumes, vegetables, and meats
FLUORIDE
Mineralisation of the fetal teeth
Fluoride supplement = cause tooth decay
2.9 mg/day
Sources: fluoridated water
ENERGY NUTRIENT
B VITAMINS ASSOCIATED WITH ENERGY & PROTEIN INTAKE
Increase of Vitamin B6 is proportional with the increase of protein
Increase of Vitamin B is proportional to the increase of energy
Riboflavin: 54 mg/day
Niacin: 7.5 mg NE
Thiamin: 1.5 mg/day
PROTEIN
+7.5 gram/day
Sources: whole grains, meats, milk, legumes
Needed for expansion of maternal blood volume & the growth of fetus, placenta and maternal tissue.
High protein supplement can be harmful
(lower birth weight, preterm birth & neonatal death)
and is discouraged.
CARBOHYDRATE
Comprise 45 - 64% of daily calories
Sources: milks, legumes, fruits, grains and vegetables
50% of total daily energy comes from carbohydrate
Needs extra food energy: 300kcal 1st trimester, +360kcal/day 2nd trimester & +470kcal/day 3rd trimester
OTHER NUTRIENTS
VITAMIN A
Deficiency= fetal retardation, preterm birth, low birth weight
27-29 μg/day
Source of food: carrot, pumpkins, liver, milk, eggs, potatoes
VITAMIN E
functions as a lipid-soluble antioxidant, protecting cells of the body from damage by harmful free radicals
7.5 mg/day
Sources: vegetable oil, wheat germ, whole grains and nuts
VITAMIN C
Form the collagen
– Collagen gives the structure to bone, cartilage, muscle and blood vessel
7-10 mg/day
Higher intake for = women with multiple fetuses, uses illicit drugs, smoke cigarette or drink alcohol :
IODINE
regulate body temperature, metabolic rate, reproduction, growth, the making of blood cells, nerve and muscle function
iodine deficiency impairs fetal development, causing mental and physical retardation (cretinism)
250 mcg/day
NUTRIENTS FOR BLOOD PRODUCTION & CELL GROWTH
VITAMIN B12
2.6 μg/day
Sources: meat, fish, eggs and milk products
Activate the folate and required for normal cell division and protein synthesis
Vegetarian; risk of B12 deficiency, need soy milk and cereal that is fortified with B12 and daily supplement.
IRON
Mother will loss lots of blood during delivery
30 mg/day
Fetal need the iron to store its own to last through 4 to 6 months after birth
Sources: liver, lean meat, fortified bread and dried beans / peas
Needed to support enlarged blood volume and to provide for placental and fetal need
FOLATE
1000 μg/day
Sources: Green vegetables, liver and nut
Play fundamental role in DNA synthesis and cell replication
Deficiency can cause placental and fetal abnormalities
Take tablet supplement of folate if dietary intake is inadequate

ZINC
Sources: meat, fish, poultry, oyster, crabmeat, shrimp
Vegetarian: oyster, pumpkin seeds, milk, chickpeas, instant oatmeal, almonds
7-10 mg/day
Required for DNA and RNA synthesis, protein synthesis and cell development
Excessive routine supplementation is not recommended
FOOD CHOICES DURING PREGNANCIES
BELIEFS & SUPERSTITIONS
Irrational
Women believe that over consumption or under consumption of craved food imparts physical or behavioral peculiarities to the infant
CRAVINGS AND AVERSION
These likes and dislikes are common
They did not reflect physiological needs
Due to physiological factors or hormone-induce changes in sensitivity to taste and smell
VEGETARIAN
well planned vegetarian diets that are adequate in food energy and include milk products and eggs can support a healthy pregnancy
Sources: milk, milk product, legumes, cereals, fruits and vegetables
Strict vegetarian may require supplementation of vitamin B12, vitamin D, calcium and iron, fortified soy milk and tofu, legumes, nuts, seeds, whole grain breads, cereal, vegetable
LACTATION
WATER
major nutrient breast milk
The amount of water taken does not depend on output of milk
drink a lot of water to prevent dehydration during lactation
drinks after each meal and each time the baby nurses
CARBOHYDRATE
It does not affect the carbohydrates in the milk content if you eat a lot of carbohydrates
source food: beans, potatoes, bread and milk
PROTEIN
It does not effect the protein in the milk if you eat a lot of protein
source food: lean meats, poultry, egg and milk
LIPID
Maternal diet alters fatty acid composition of breast
milk, but not the total fat concentration of breast milk.
Docosahexaenoic Acid (DHA) increase if mother consumes oil rich in DHA.
cholesterol is unaffected.
DHA will increases of breast milk levels of the essential fatty acid.
NUTRIENT SUPPLEMENT
well-balanced diet
Some would need iron extra for iron deficiency replenishment.
vegetarian women will need supplement to ensure the body has adequate absorption nutrients for the infant..
CHARACTERISTIC OF BREAST MILK
carbohydrate
disaccharide lactose.
easily digested and facilitates calcium absorption
oligosaccharides and bifidus factor-nonlactose carbohydrate
defend infants against harmful bacteria
Contains amylase enzyme that facilitates
starch digestion
protein
low protein concentration contribute low renal solute load
alpha-lactalbumin
efficiently digested and absorbed, richer in sulphur containing acid amino
all essential acid amino in appropriate amounts
lipid
source of energy in infant diet
infant digest fat in breast milk completely
infants absorb monoglycerides with palmitic acid more efficiently
Breast milk contains more than adequate
concentration of the essential fatty acid
vitamins and mineral
Breast milk contains all the vitamin and
minerals needed for normal infant.
Low electrolyte – low renal solute load
low zinc quantities but efficient absorption because of the presence of binding proteins
contains amylase enzyme facilitates starch digestion
protein factors
bifidus factor
Microbial growth factors favoring the growth of
harmless bacteria in the digestive tract
immunoglobulins
Protects the infant digestive tract against antigen
colostrum
A premilk substances that contain mainly serum with
antibodies and white blood cells
health advantages
Protect infants against gastrointestinal
infections
Protection against the development of
allergies
Wide spectrum of flavors it introduces to
an infant
VITAMIN & MINERAL
fat soluble vitamins
breast milk may change with maternal dietary excesses and deficiencies of fat soluble vitamin
vitamin A, D, E, K
water soluble vitamin
reflects maternal intake. several vitamin deficient mothers produce several deficient breast milk
vitamin C, riboflavin, thiamin
mineral
unaffected by maternal diet

NUTRITION DURING LABOR
easier if pregnant women are well
nourished and well hydrated at the start
it is wise to eat periodically: take snacks along when going to the birthing center or hospital
