Breast Milk or Formula: Making the Right
Choice for Your Baby
by Rebecca D. Williams and Isadora Stehlin
New parents want to give their babies the very best. When it comes
to nutrition, the best first food for babies is breast milk.
More than two decades of research have established that breast
milk is perfectly suited to nourish infants and protect them from
illness. Breast-fed infants have lower rates of hospital admissions,
ear infections, diarrhea, rashes, allergies, and other medical problems
than bottle-fed babies.
"There are 4,000 species of mammals, and they all make a different
milk. Human milk is made for human infants, and it meets all their
specific nutrient needs," says Ruth Lawrence, M.D., professor
of pediatrics and obstetrics at the University of Rochester School
of Medicine in Rochester, N.Y., and spokeswoman for the American
Academy of Pediatrics.
Health experts say increased breast-feeding rates would save consumers
money, spent both on infant formula and in health-care dollars.
It could save lives as well.
"We've known for years that the death rates in Third World
countries are lower among breast-fed babies," says Lawrence.
"Breast-fed babies are healthier and have fewer infections
than formula-fed babies."
Although breast-feeding is still the best nourishment for infants,
infant formula is a close enough second that babies not only survive
but thrive.
Commercially prepared formulas are regulated by the Food and Drug
Administration.
The nutritional adequacy of commercially prepared formula is also
ensured by the agency's nutrient requirements and its safety by
strict quality control procedures that require manufacturers to
analyze each batch of formula for required nutrients, to test samples
for stability during the shelf life of the product, to code containers
to identify the batch, and to make all records available to FDA
investigators.
The composition of infant formula is similar to breast milk, but
it isn't a perfect match, because the exact chemical makeup of breast
milk is still unknown.
Human milk is very complex, and scientists are still trying to
unravel and understand what makes it such a good source of nutrition
for rapidly growing and developing infants.
More than half the calories in breast milk come from fat, and the
same is true for today's infant formulas. This may be alarming to
many American adults watching their intake of fat and cholesterol,
especially when sources of saturated fats, such as coconut oil,
are used in formulas. (In adults, high intakes of saturated fats
tend to increase blood cholesterol levels more than other fats or
oils.) But the low-fat diet recommended for adults doesn't apply
to infants.
The reason is that infants have a high energy requirement, and
they have a restricted volume of food that they can ingest. The
way to meet these energy requirements in a restricted amount of
food is to have a high amount of fat.
While greater knowledge about human milk has helped scientists
improve infant formula, it has become "increasingly apparent
that infant formula can never duplicate human milk," wrote
John D. Benson, Ph.D, and Mark L. Masor, Ph.D., in the March 1994
issue of Endocrine Regulations. "Human milk contains living
cells, hormones, active enzymes, immunoglobulins and compounds with
unique structures that cannot be replicated in infant formula."
Benson and Masor, both of whom are pediatric nutrition researchers
at infant formula manufacturer Abbott Laboratories, believe creating
formula that duplicates human milk is impossible. "A better
goal is to match the performance of the breastfed infant,"
they wrote. Performance is measured by the infant's growth, absorption
of nutrients, gastrointestinal tolerance, and reactions in blood.
