232 Toxic Chemicals found in 10 Babies

 

Laboratory tests commissioned by the Environmental Working Group have detected bisphenol A (BPA), a plastic component and synthetic estrogen, in umbilical cord blood of American infants.
Nine of 10 randomly selected samples of cord blood tested positive for BPA, an industrial petrochemical.

BPA has been implicated in a lengthening list of serious chronic disorders, including cancer, cognitive and behavioral impairments, endocrine system disruption, reproductive and cardiovascular system abnormalities, diabetes, asthma and obesity.

In all, the tests found as many as 232 chemicals in the 10 newborns, all of minority descent. The cord blood study has produced hard new evidence that American children are being exposed, beginning in the womb, to complex mixtures of dangerous substances that may have lifelong consequences.

And in a separate study, researchers found that complications of pregnancy, such as preterm labor, preterm birth, and infection were lowest in women with the highest vitamin D levels.

Blood levels of activated vitamin D usually rise during very early pregnancy, and some of it crosses the placenta to bathe the fetus, especially the developing fetal brain, in activated vitamin D. But many — in fact most — pregnant women do not make as much vitamin D as they need.

4,000 IU of vitamin D per day during pregnancy was found to be safe (not a single adverse event). However, this amount only resulted in a mean vitamin D blood level of 27 ng/ml in the newborn infants, indicating that even 4,000 IU per day during pregnancy is not enough.

Creams Can Make Skin Drier

A new research has confirmed for the first time that normal skin can become drier from creams.
………………………………CLICK & SEE.

The findings are based on Izabela Buraczewska’s study, in which she looked at what happens to the skin at the molecular level and also what positive and negative effects creams have on the skin. Her research has revealed that differences in the pH of creams do not seem to play any role.

She also studied different oils in a seven-week treatment period, but no difference was established between mineral oil and a vegetable oil. Both oils resulted in the skin being less able to cope with external stresses. Buraczewska and her team concluded that the contents of creams impact the effects on the skin. Buraczewska presented these findings in the dissertation she is publicly defending at Uppsala University in Sweden this month.

Exercise During Pregnancy Means a Healthier Heart for Both Mom and Baby

Exercise is good not only for mothers-to-be, but also for their developing babies, according to a new study by researchers from Kansas City University of Medicine and Biosciences.

………………………………..….CLICK & SEE

Maternal exercise during pregnancy may have a beneficial effect on fetal cardiac programming by reducing fetal heart rate and increasing heart rate variability. Researchers studied fetal heart rates with magnetocardiography (MCG), a safe, non-invasive method used to record the magnetic field surrounding the electrical currents generated by the fetal heart and nervous system.

There were significantly lower heart rates among fetuses that had been exposed to maternal exercise. The heart rates among non-exposed fetuses were higher, regardless of the fetal activity or the gestational age.

The researchers concluded that exercising during pregnancy can benefit a mother’s own heart and her developing baby’s heart as well.
