Infant Formula Manufacturers' 'Marketing Gimmick' Linked to Serious Illness

A report released today by The Cornucopia Institute presents research indicating that new additives placed in infant formula are seriously endangering the health of
some formula-fed newborns and toddlers.

The report, 'Replacing Mother--Imitating Human Breast Milk in the Laboratory,' details research questioning the alleged benefits of adding "novel" omega-3 fatty acids, produced in laboratories and extracted from algae and fungus, into infant formulas. The additives raised health and safety red flags during preapproval testing while aggressive marketing campaigns by some infant formula manufacturers appear to have encouraged new mothers to give up nursing for the questionable products, according to a statement by the institute.

"When I worked in the hospital's neonatal ward, the nurses all called it 'the diarrhea formula'," says Sam Heather Doak, LPN, IBCLC, from Marietta, Ohio. "We've seen infants, tiny little humans, with diarrhea that just wouldn't stop after being given this formula." For infants, virulent and long-term diarrhea is considered a serious and life-threatening event.

The infant formula referenced by Doak was supplemented with Martek Biosciences Corporation's laboratory-produced oils containing DHA and ARA. DHA, an omega-3 fatty acid, and ARA, an omega-6 fatty acid, are naturally found in human breast milk and are considered important nutrients for infants.

But laboratory-produced DHASCO and ARASCO (Martek's names for their proprietary oils) are materially different from the fats found in a mother's breast milk. Martek's products are extracted from fermented algae and fungus, with the use of the neurotoxic solvent hexane. They contain only 40 percent to 50 percent DHA and ARA, with the balance from sunflower oil and other components, including some not found in human breast milk and never before a part of the human infant diet, the statement says.

"It's true that DHA and ARA are important nutrients for developing infants--that's why they're found in human breast milk. But we have also seen that some infants are experiencing side effects like diarrhea from consuming the manufactured DHA and ARA oils in formula," says Jimi Francis, a biochemist specializing in DHA in infant nutrition at the Allie M. Lee Laboratory for Omega-3 Research at the University of Nevada at Reno.

Also, humans produce DHA and ARA on their own from other fats.

Study Notes Decline in Male Births in US, Japan


A study published in this week’s online edition of Environmental Health Perspectives reports that during the past 30 years, the number of male births has decreased each year in the U.S. and Japan. In a review of all births in both countries, the University of Pittsburgh-led study found significantly fewer boys being born relative to girls in the U.S. and Japan, and that an increasing proportion of fetuses that die are male.

They note that the decline in births is equivalent to 135,000 fewer white males in the U.S. and 127,000 fewer males in Japan over the past three decades and suggest that environmental factors are one explanation for these trends.

“The pattern of decline in the ratio of male to female births remains largely unexplained,” says Devra Lee Davis, lead investigator of the study, director of the University of Pittsburgh Cancer Institute’s Center for Environmental Oncology and professor of epidemiology, University of Pittsburgh Graduate School of Public Health. “We know that men who work with some solvents, metals and pesticides father fewer baby boys. We also know that nutritional factors, physical health and chemical exposures of pregnant women affect their ability to have children and the health of their offspring. We suspect that some combination of these factors, along with older age of parents, may account for decreasing male births.”

Davis explains that environmental factors, such as prenatal exposure to endocrine--disrupting environmental pollutants may impact the SRY gene – a gene on the Y chromosome that determines the sex of a fertilized egg. Other environmental factors that also may affect the viability of a male fetus include the parents’ weight, nutrition and the use of alcohol and drugs.

In the study, Davis and her colleagues reported an overall decline of 17 males per 10,000 births in the U.S. and a decline of 37 males per 10,000 births in Japan since 1970. They also found that while fetal death rates have generally decreased, the proportion of male fetuses that die has continued to increase. In Japan, among the fetuses that die, two-thirds are male, up from just over half in 1970.

The study also examined the ratio of African-American male to female births to that of whites in the U.S. The researchers found that while the number of African-American male births has increased modestly over time, the ratio of male to female births for African-Americans remains lower than that of whites. In addition, they noted that African-Americans have a higher fetal mortality rate overall and a higher proportion of male fetuses that die.

“These results are not surprising since the black-white ratio in terms of infant mortality has remained the same for almost 100 years,” says Lovell Jones, study co-investigator and professor and director, Center for Research on Minority Health, department of health disparities research, University of Texas M.D. Anderson Cancer Center. “Given the higher mortality rates for African-American males in the United States, these results reemphasize the need to determine all factors, including environmental contaminants, which are responsible for this continuing health disparity.”
