Guest guest Posted December 23, 2003 Report Share Posted December 23, 2003 http://mercola.com/2003/dec/24/formula_influence.htm The Deadly Influence of Formula in America, Part I [ Part I, By Dr. Linda Folden Palmer First published on Natural Family Online This groundbreaking analysis from noted author, health educator and advocate Dr. Linda Folden Palmer is the first time a health expert has published an examination of the available scientific research comparing the death rates of formula-fed and breastfed babies. While the results hold no surprises for breastfeeding educators and advocates, the study may prove to be a rude awakening for the millions of Americans who have bought into the myth that infant formula is a perfectly safe breast milk substitute. Infant formula was designed to be a medical nutritional tool for babies who are unable to breastfeed. Formula does not fully meet the nutritional and immunity needs of infants, leaving their immune systems flailing. An infant’s immune system has three aspects: her own immature, developing immune system; the small component of immunities that passes through the placenta during natural childbirth (and to a lesser degree with premature births and cesarean sections); and the most valuable, living portion that is passed on through mother’s milk on an ongoing basis. Remove any of these components and you take away a vital support structure. This brings us face to face with the safety and effectiveness of infant formula as a breast milk substitute. Is formula actually as safe as we have been led to believe? In fact, the answer is a resounding “no.” In fact, the use of infant formula doubles the risk of infant death for American babies. While the dangers of formula feeding aren’t something you’re likely to hear in your doctor’s office, the conclusions can be derived through an examination of the available scientific research on infant mortality in the United States and across the world. There are studies showing artificial feeding’s impact on overall infant death rates in both developing and undeveloped countries. While studies offering comparative death rates are not available for industrialized regions, there are numerous studies providing comparative occurrence rates for many illnesses and disorders in the United States and other industrialized nations. Many more reports are available extolling superior survival rates and decreased illness rates among breastfed infants, but only those with solid numbers are useful here. We can assemble the statistics from these studies to build a firm picture of the ratio of infant deaths for U.S. formula-fed babies against those who are breastfed. The relative risks of formula It is clear that feeding infants artificial formula instead of breastfeeding increases their relative risk of death. A number of studies point to this fact. Table 1 shows figures from two studies measuring infant mortality risks during certain age ranges. A risk number of 3 in the chart represents three times the risk of infant death for infants who are artificially fed. While the numbers in the charts reflect any amount of breastfeeding during the study period (and not necessarily exclusive breastfeeding), nearly all studies mention that during the first six months, exclusive breastfeeding produces much higher survival rates than partial breastfeeding. No studies refute this assertion. Figures for each age range listed here do not include children who died prior to reaching that age group. Figures reflect infants who received no breast milk or had weaned prior to reaching the reported age group versus those who received any breastfeeding through that age. Table 1 clearly demonstrates that the disadvantages of formula are most devastating in the earliest months. Significant disadvantages for formula continue throughout the year-long study period.

The studies cited in the next table compare no breastfeeding with 12 months of breastfeeding, each deriving a relative risk of death over the full first year.

A relative risk of 5 here means that an infant who receives formula statistically faces five times the risk of dying as an infant who is partially or completely breastfed. * These values are calculated from numbers provided in the studies, with averages weighted by percentages of total deaths occurring in each age range. More than two-thirds of deaths occur during the first month. While the United States has a current infant mortality rate of 6.75 per thousand, many countries have rates approaching 100, with 16 of 225 reporting nations suffering well over 100 infant deaths for every 1,000 children born.(8) The nations in the above table with lower infant mortality rates can thus be seen as somewhat comparable to the United States. Factors influencing high infant death rates include malnourished mothers, high numbers of births per mother with short spacing between births, poor weaning foods, the early use of cow’s milk, inadequate medical attention and supplies, poor sanitation leading to high infection rates and a rapid spread of infectious disease, and limited education about methods of limiting infection and the spread of disease. Why do U.S. babies die? Below are the percentages and total numbers of U.S. infants who die from various leading causes, according to the 1999 National Vital Statistics Reports.

Let’s look at some of the common causes of infant death and see what current research has to say on the involvement of infant formula. Sudden Infant Death Syndrome (SIDS) Sudden Infant Death Syndrome (SIDS) accounts for a full 10 percent of U.S. infant deaths. Several studies performed in the United States and other industrialized nations reveal increased risks of SIDS among babies who receive formula instead of breast milk. In the table below, the 2002 Scandinavian study takes into account variables thought to have affected the 2000 U.S. study, finding even stronger risks associated with formula. The most recent U.S. study (2003) takes advantage of the lessons from these earlier studies to raise confidence in its final results. Its finding of five times the risk of infant death from SIDS for formula-fed infants seems to be the most powerful statistic yet.

Heart, Circulatory and Respiratory Failure Premature infants and those with circulatory abnormalities often display one or more warning signs of potential death, including inadequate oxygenation of the blood, apnea (episodes where breathing stops) and high blood pressure. Studies illustrate the dangers of formula for these infants. One study observed better body temperature and superior oxygenation in pre-term infants receiving breast milk. Formula-fed infants demonstrated many episodes of inadequate oxygenation and some apnea, both of which were not seen among the breastfed infants. A Scottish study found significantly better blood pressure among naturally fed infants. Three U.S. studies are available examining feeding methods for infants with early circulatory problems. One study reported that more than half of infants with congenital heart disease lost oxygenation during bottle feedings, while none did so while breastfeeding. Another study also dealing with heart disease found infants’ growth to be significantly inferior and their hospitalizations to be longer when they were fed formula. A third study of very low birth-weight infants found twice as many episodes of inadequate oxygenation among formula-fed infants as in those who received breast milk.

About one-third of low birth-weight infants and 20 percent of full-term infants who contract this disorder die. While necrotizing enterocolitis is reported to be responsible for 1.4 percent of infant deaths, many more unconfirmed cases are likely to be responsible for some portion of infant deaths reported as caused by prematurity. In the United Kingdom, it was discovered that confirmed cases of necrotizing enterocolitis occurred in three times as many infants who received no breast milk as in those who received both breast milk and formula. For infants who exclusively received breast milk, necrotizing enterocolitis occurred six to 10 times less often than among wholly formula-fed infants. Necrotizing Enterocolitis (23) Country Author YearRelative risk of necrotizing enterocolitis, formula-fed infantsUnited Kingdom Lucas 1990 6-10 times more often Diarrhea A World Health Organization (WHO) study revealed a risk of diarrhea for formula-fed babies in developing nations averaging more than six times that of breastfed babies. A summary article for industrialized nations demonstrated an average of triple the risk of diarrhea for formula-fed babies. The risk in China and Israel is reported as slightly less than triple (2.8); in Scotland, the risk is five-fold; and a doubled risk is measured in Canada. While one study noted nearly twice the risk of developing diarrhea for artificially fed infants in Brazil, other studies have demonstrated that the risk of actually dying from diarrhea was an astounding 14 to 15 times greater. The latter studies demonstrated not only that the artificially fed infants suffer higher rates of illness, but also that the severity and duration of their illnesses are even greater when they do occur and result in proportionately more deaths. This same assertion is demonstrated in a study from India, where formula-fed infants suffer six times the death rate, once diarrhea occurs, as breastfed infants with diarrhea. Four separate studies in the United States all deduce a doubled risk of diarrhea for formula-fed babies. The U.S. studies also reiterate the well-established factor of greater severity and extent of illness once diarrhea does occur among formula-fed babies. Death rates for formula-fed U.S. infants who get diarrhea may be three times higher or more than their breastfed contemporaries. The table below collates the reported risks of diarrhea for formula-fed infants from many studies.

[ Part I, Part II ] Next >> Dr. Linda Folden Palmer consults and lectures on natural infant health, optimal child nutrition and attachment parenting. After running a successful chiropractic practice focused on nutrition and women's health for more than a decade, Linda's life became transformed eight years ago by the birth of her son. Her research into his particular health challenges led her to write Baby Matters: What Your Doctor May Not Tell You About Caring for Your Baby. Extensively documented, this healthy parenting book presents the scientific evidence behind attachment parenting practices, supporting baby's immune system, preventing colic and sparing drug usage. You can visit Linda's Web site at www.babyreference.com. Dr. Mercola's Comment: It is good to see that attention is being given to the importance of breastfeeding. Breastfeeding your newborn is the best way to give her all the nutrients she needs to develop into a strong, healthy child. I encourage every mother who is able to breastfeed her newborn. However, there are cases when a woman may be unable to breastfeed for physical reasons. In these cases, it’s important to recognize that ALL soy formula is worse than worthless for human infants and is nearly guaranteed to cause problems down the road. What are some of the problems associated with soy formula? Well, for starters it: Will adversely affect hormone levels, as it has been associated with reduced testosterone levels Will impair thyroid function through isoflavones present in the formula Increases the risk of behavioral problems Will expose infants to up to 2,000 times higher estrogen content Has potentially high concentrations of aluminum and manganese Soy formula is generally given to infants who aren't breastfeeding and have trouble taking regular cow-milk-based infant formulas. While I am no fan of these formulas either, they tend to be safer than soy formula. However, the cow-milk-based formulas are derived from pasteurized milk. If you haven't heard by now pasteurized milk is not good for you or your baby. Fortunately, you can use raw milk to produce a terrific infant formula, but, again, remember that breast milk is ALWAYS best.
