In the meantime, commercial infant formulas are not only distant in composition from human milk, but various brands of synthetic milks aren’t even comparable to one another. Contrary to what the name implies, there is no fixed “formula” for commercial synthetic milk. Content and quantities of nutrients vary widely between brands and types of formula (soy, cow’s milk, and meat-based). According to formula manufacturers, a pediatrician should recommend an appropriate brand and type of formula for each particular baby–advice implying that each baby’s nutritional needs are unique and that physicians can recognize these special needs upon examination and select a formula accordingly. This is, of course, neither accurate nor possible.

Compositional variance between formulas persists because manufacturers must attempt to simulate a product for which they do not have the recipe – a fact FDA officials recognize in their recent statement that “. . . . the exact chemical makeup of breast milk is still unknown.” As Marsha Walker notes, “Formula-fed infants depend on products which can be quite different from each other, but which are continually being found deficient in essential nutrients . . . These nutrients are then added, usually after damage has occurred in infants or overwhelming market pressure forces the issue.”

Iron fortification serves as a startling example of this ongoing experimentation on infant consumers. Today’s breast milk substitutes are designated as either iron-fortified or low-iron. However, William J. Klish, M.D., chairman of the American Academy of Pediatrics Committee on Nutrition (the body which recommends formula-nutrient requirements to the FDA) states: “There should not be a low-iron formula on the market for the average child because a low-iron formula is nutritionally deficient.”

CHOOSING FORMULA

Be sure to choose a DHA-enriched formula. Most, if not all of the US formula companies will offer AA/DHA-enriched formulas. For information about the brain-building benefits of DHA, try Dr. Sears’ Go Fish DHA soft gels.

When it comes to infant formula, parents need to know a few simple facts:

There are some subtle differences among the major brands of infant formulas which may affect how your baby tolerates one formula over another. Reading the labels may leave you feeling like you need a Ph.D in biochemistry to make an intelligent decision. We want to help you with an analysis of the big three nutrients: proteins, fats, and carbohydrates. The vitamins and minerals in all formulas are similar, since these are governed by strict regulations, however, the nutritional fine points of the fats, carbohydrates, and proteins differ from one brand to another, as the marketing departments of each company are very willing to point out, especially to pediatricians.
