Transcript Formula Feeding of Infants

Formula Feeding
of Infants
There is an agreement among
healthcare professionals, infant
food manufacturers and mothers
that breastfeeding is the best
choice for feeding infants during
their first four to six months of
life
There are several reasons why a
mother may not breastfeed her
baby:
1. Medical or other health reasons
may prevent a mother from
breastfeeding.
2. The baby with special requirements
may not tolerate breast milk.
3. Some social or psychological
reasons can make it more difficult
to breastfeed exclusively.
The absolute
contraindications to breastfeeding
1. Hypergalactosaemia.
2. Phenylketonuria [PKU].
3. Lactose intolerance.

Other reasons why a mother
may not breastfeed her
baby:
•
•
Working outside the home makes it more
difficult to breastfeed exclusively,
especially if there is no support at her
workplace for her to either bring her
baby or to express and store her milk.
Choosing not to breastfeed for personal
reasons, either from the birth of the
baby or after breastfeeding for a short
while, is a mother's prerogative.
Recommendations for
Working Women:
• The mother who goes back to work can usually
continue breast-feeding without problems.
The milk supply adjusts itself to the demand.
If the mother is working at least 8 hours a
day, it is sometimes prudent to pump the
breasts once during her work day in order to
stay comfortable and maintain a good milk
supply. Each woman is different in what is
required to maintain a supply. Some women
can work for a long time without pumping and
without compromising the supply. Others have
a supply that is more responsive to decreased
feeds. A woman will rarely “dry up” becayse
she has returned to work.
• Working mothers, however, can easily breastfeed part-time and formula-feed part-time.
Breast pumps and
storage of milk
• Hand expression is superior if the mother
can learn the technique.
• Several pumps are available if the mother
is unable to express by hand.
• It is good if the woman can borrow a pump
from a friend before she decides which
pump to purchase. Another alternative is
to rent an electric pump.
• Milk should be stored in clean containers
and immediately refrigerated or frozen.
– If refrigerated, it will stay good for 48 hours.
– If frozen at 0°F, it wiil keep for months.
Recommendations for
mother’s diet:
• To drink approximately 64 oz of fluids per
day.
• The nursing mother requires an additional
500 calories and 20-30 g of protein a day.
• She has to take her prenatal vitamins with
iron.
• The mother need not to avoid certain foods
unless she observes consistent increased
fussiness in the baby in association with the
mother ingestion such foods.
Foods commonly incriminated:
• Garlic
• Onions
• Cabbage
• Chocolate
• Great quantities of caffeine.
Nursing mother may drink small amounts of
alcohol: a glass of sherry or wine may be
beneficial in late afternoon if she is having
let-down reflex problems.
Common problems encountered
with brest-feeding
• Poor Let-Down (Milk ejection
reflex)
• Poor Weight Gain
• Mastitis
• Cracked Nipples
• Jaundice From Breast- Feeding
Artificial feeding
• This is the feeding of infant when he
gets cow’s or buffalo’s milk or
formula from first days till 4th to 6th
month of his life.
• Formula milks are humanized, i.e.,
they come very close to the
composition of breast milk.
• However, they are more expensive,
so cow’s or buffalo’s milk are quite
often used.

Other advantages of breast
milk versus cow’s milk:
• Breast milk is available all the time and is
practically free from pathogenic bacteria.
• It needs no time for preparation
• It is available at the optimum temperature.
• It contains antibodies as IgG and IgA and
protects against certain infections such as
E.Coli, cholera, polio, tetanus, measles etc. IgA
antibodies prevent the microorganisms to
adhere the intestinal mucosa and provide local
GIT immunity.
• β-lactose is called Bifidus factor, which
promotes the growth of lactobacillus and helps
to lower the gut pH, thus inhibiting the growth
of E.Coli and yeasts.
• Breast milk contains lactoferrin (an ironbinding whey protein), which inhibits bacterial
growth by depriving them of iron, which is
necessary for growth.
• Breast milk contains cystine and tyrosine,
which are not synthesized by infants but they
are essential for proper growth and
development.
• Breast milk contains taurine that is
synthesized in inadequate amounts in infants.
It is important for normal differentiation of
CNS.
• Breast milk contains nonspecific factors of
immune difence: lisozyme, macrofagocytes,
neutrofiles, lymphocytes, complement
system.
• There are 5 times more essential fatty
acids (polyunsaturated: arachidonic,
docosahexacnoic, linoleic, and α-linolenic)
in breasts milk than in cow’s milk.
• Breast milk contains ferments (lipase,
lactase) and mothers hormones.
• Breast milk is ‘species specific’ and
therefore allergy to breast milk is rare.

Advances in nutritional
modifications of infant
formulas
• Proteins: their amount is adopted to the
needs of infant’s organism. Almoust all
formulas contain whey:casein ratio as
60:40 and adopted amino acid content.

• Fats: long-chain polyunsaturated
fatty acids are added in amounts
similar to those in human milk.
Infants fed these formulas or human
milk have higher tissue
concentrations of long-chain
polyunsaturated fatty acids and
reportedly have better visual acuity
than do infants fed nonsupplemented
formulas.
• Carbohydrates: they are presented
by β-lactose, sakcharose, dextrinmaltose, which improve the growth of
Bifidum-bacteria. The total quantity
of carbohydrates in formulas is 7.5 %
• Nucleotides and their related products
play key roles in many biological
processes. Although nucleotides can be
synthesized endogertously, they are
considered "conditionally essential."
Nucleotide concentrations in human
milk are higher than in unsupplemented
cow milk-based formulas, and studies
in animals and human infants suggest
that dietary nucleotides play a role in
the development of the
gastrointestinal and immune systems
