Reading Tom Hale's research and comments on the effects of iron on
stimulating growth of yeast, and perhaps other pathogens - it makes
sense that non-breastfed or formula-fed infants with excessive levels of
non-biologic iron would have more infections, doesn't it?

 Of course, any lactation consultant could have told them this about
oxytocin.  Note the last study talks about "formula fed, partially
breastfed, and predominantly breastfed"  no "exclusively breastfed"
infants mentioned.
 

Study suggests breastfeeding may promote maternal bonds through a
biochemical process.

cS1&mt=1> UPI (7/19) reported that "[b]reastfeeding a baby results in
surges of the 'trust' hormone oxytocin in the mother's brain," according
to a study published in PLoS Computational Biology. The collaborative
team of scientists, hailing from the U.K., France, and Italy, explained
that "oxytocin has long been known to be the trigger that, when released
into the blood, causes milk to be let down from the mammary gland." 

        Specifically, "large, regular pulses of oxytocin are needed to
create the wave released when a mother breastfeeds," added the U.K.'s

IzND
cS1&mt=1> Press Association (7/19). Now, the team has discovered "a
likely answer to how the few thousand neurons, which are specialized to
release oxytocin, are marshaled together to create th[at] wave." 

        In "response to a baby suckling," the "specialized neurons in
the mothers' brain start to release the hormone from the nerve endings,"
noted the

S1&mt=1> BBC (7/19). Yet, "surprisingly, oxytocin is also released from
the part of the cell called the dendrite, which is usually the part of a
neuron which receives, rather than transmits information." Moreover,
through the use of "a mathematical model, the researchers worked out
that this release from the dendrites allows a massive increase in
communication between the neurons, coordinating a 'swarm' of oxytocin
factories producing intense bursts of the hormone." 

        This "results in a massive rush of the 'love hormone' oxytocin
in women's brains," reported the U.K.'s

cS1&mt=1> Daily Mail (7/18, Derbyshire). It is an effect that may
augment "a mother's feelings of trust, love, and affection, scientists
say." 

        According to study co-author Jianfeng Feng, of the University of
Warwick, the researchers "have shown that the dendritic interactions are
enhanced enough to trigger a massive positive-feedback on activity,"
noted

cS1&mt=1> HealthDay (7/18). "The model gives us a possible explanation
of an important event in the brain that could be used to study and
explain many other similar brain activities," Feng concluded. 

        Breastfed infants may be less likely to develop GI infections,
study indicates.

cS1&mt=1> HealthDay (7/18, Doheny) reported, "Infants who are
predominantly breastfed for the first six months of life are less likely
to have gastrointestinal problems (GI)," according to a study published
in the August issue of the Journal of Nutrition. But, those children are
"more likely to be deficient in iron, and therefore at risk of anemia."
In the study, researchers "compared a formula-fed group of about 50
babies with 55 partially breastfed and 49 predominantly breastfed
infants from birth through six months, noting episodes of GI infections
by asking the mothers about symptoms." The results showed that 18
percent of the predominantly breastfed group had GI infections, while 33
percent of the partially breast-fed or formula-fed group had GI
infections.
