Timing of
babies` first solid food critical in preventing diabetes
An early and late first exposure to
solid food for infants might be associated with the development of type 1
diabetes mellitus (T1DM), a new study has revealed.
The research conducted by Colorado School of Public Health, University of Colorado, Aurora, has found that both early- less than 4 months of age and late- greater than or equal to 6 months of age- first exposure to any solid food was associated with development of T1DM (hazard ratio [HR] 1.91, and HR, 3.02, respectively).
The results also indicated that early exposure to fruit and late exposure to rice or oat was associated with an increased risk of T1DMB (HR, 2.23 and HR, 2.88, respectively), whereas breastfeeding when wheat or barley (HR, 0.47) were introduced appeared to be associated with a decreased risk.
"Our data suggest multiple foods/antigens play a role and that there is a complex relationship between the timing and type of infant food exposures and T1DM risk. In summary, there appears to be a safe window in which to introduce solid foods between 4 and 5 months of age; solid foods should be introduced while continuing to breastfeed to minimize T1DM risk in genetically susceptible children. These findings should be replicated in a larger cohort for confirmation," the authors conclude.
The study was published in a JAMA Network publication.

Singing can
be good for heart
Washington:
A new study has found that when people sing in a choir their heart beats are
synchronised, their pulse tends to increase and decrease in unison.
This has
been shown by a study from the Sahlgrenska Academy at University of Gothenburg
that examined the health effects for choir members.
In the
research project "Kroppens Partitur" (The Body`s Musical Score),
researchers at the Sahlgrenska Academy are studying how music, in purely
biological terms, affects our body and our health.
The object
is to find new forms where music may be used for medical purposes, primarily
within rehabilitation and preventive care.
In the
latest study, the research group is able to show how the musical structure
influences the heart rate of choir members.
In December 2012, Bjorn Vickhoff and his research group
brought together fifteen 18-year-olds at Hvitfeltska High School in Gothenburg
and arranged for them to perform three different choral exercises: monotone
humming, singing the well-known Swedish hymn "Harlig ar Jorden"
(Lovely is the Earth) as well as the chanting of a slow mantra.
The heart rhythm of the choir members was registered as they performed in each case.
The results from the study show that the music`s melody and structure has a direct link is linked to the cardiac activity of the individual choir member; to sing in unison has a synchronising effect so that the heart rate of the singers tends to increase and decrease at the same time.
The researchers` hypothesis is that the health effects arise through singing "imposing" a calm and regular breathing pattern which has a dramatic effect on heart rate variability - something that, in its turn, is assumed to have a favourable effect on health.
The study is published in the open-access journal Frontiers in Neuroscience.
