The
American Academy of Pediatrics says "the normal breast-fed infant
of the well-nourished mother has not been shown conclusively to need any
specific vitamin and mineral supplement. Similarly, there is no evidence
that supplementation is necessary for the full-term, formula-fed infant
and for the properly nourished normal child."
Many physicians recommend supplements, nevertheless--especially
for breast-fed infants.
The controversy on supplements usually revolves around the following:
* Iron--Although the amount of iron in breast milk is very low
(0.3 milligrams of iron per liter), the infant absorbs almost half.
In contrast, while iron-fortified formulas contain 10 to 12 mg per liter,
babies absorb only about 4 percent, amounting to about 0.4 mg per liter
to 0.5 mg per liter. In either case, those amounts of iron are adequate
for the first 4 to 6 months, according to the American Academy of Pediatrics.
In the past, there was concern that iron-fortified formulas could cause
gastrointestinal problems such as colic, constipation, diarrhea, or
vomiting. But, based on several studies over the last 10 years, the
American Academy of Pediatrics does not believe there is any evidence
connecting these problems to iron and recommends that iron-fortified
formula be used for all formula-fed infants.
* Vitamin D--Insufficient vitamin D can cause rickets, a disease
that results in softening and bending of the bones. Although the amounts
of vitamin D in breast milk are small, rickets is uncommon in the breast-fed
term infant. This may be because, like the iron in breast milk, the
vitamin D in breast milk is easily absorbed by the baby.
Sunlight is important for the formation of vitamin D, but probably
as little as a few minutes exposure a day is all the baby needs, says
Schanler, and exposure to the whole body isn't necessary--just the arms
and face are enough.
* Fluoride--No one knows for sure if giving fluoride during
the first six months of life will result in fewer cavities. Reflecting
the uncertainty surrounding fluoride supplements, the American Academy
of Pediatrics recommends starting fluoride supplements shortly after
birth in breast-fed infants, but also says that waiting up to six months
is acceptable. Because there is no fluoride in infant formula, that
twofold recommendation also applies when ready-to-feed formula is used
or when the water used for powdered or concentrated formula has less
than 0.3 parts per million of fluoride.
