A new study shows that exposure to fluoride may lower children‘s intelligence. Fluoride is added to 70 percent of U.S. public drinking water supplies...click & see the pictures

More than 500 children aged 8 to 13 from two different towns were studied and tested.  One city had fluoridated water, and the other did not.

PR Newswire reports:
“About 28 percent of the children in the low-fluoride area scored as bright, normal or higher intelligence compared to only 8 percent in the ‘high’ fluoride area … in the high-fluoride city, 15 percent had scores indicating mental retardation and only 6 percent in the low-fluoride city.”

Avoid Feeding Your Child Drinking Water contains excessive Manganese

According to a report in Science Daily, a new Canadian study shows that children exposed to high concentrations of manganese in drinking water performed worse on tests of intellectual functioning than children with lower exposures.

The results were published in an article in Environmental Health Perspectives.

While manganese is naturally occurring in soil and groundwater around the world, some of Canada’s groundwater contains an unusually high amount of it, giving the researchers an opportunity to study whether excessive manganese can adversely affect human health.

“We found significant deficits in the intelligence quotient (IQ) of children exposed to higher concentration of manganese in drinking water,” said lead author Maryse Bouchard.

Yet, some areas where lower IQs were reported also registered concentrations below current guidelines. In response to the study, some of the affected municipalities have already decided to install special filtration systems.

Nutrition: Fish Oil for Mom May Benefit Her Child

[amazon_link asins=’B06WGQ3VWG,B00KKA0G04,B002QMB55Y,B01NBTJFJB,B01GV4O37E,B000NPYY04,B00CAZAU62,B004U3Y9FU,B0046XC528′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’d2be76b1-db55-11e7-a984-5d05f5e7fc18′]

Women who take fish oil supplements while pregnant may improve the hand-eye coordination of their children, according to a small Australian study.

In a trial published online Dec. 21 in The Archives of Disease in Childhood: Fetal and Neonatal Edition, scientists divided 98 women into two groups. Beginning at 20 weeks of pregnancy and continuing until the women gave birth, the first group took a daily dose of four grams of fish oil, while the second group took four grams of olive oil each day. Neither the mothers nor the researchers knew which supplement the women had received until the study ended.

The researchers examined 72 children born to women who completed the study when the children were 2½ years old. In tests of locomotor ability, speech and hearing, vocabulary and practical reasoning, the children whose mothers were given fish oil during pregnancy scored slightly higher, but the differences were not statistically significant. However, after controlling for maternal age, birth weight, breast-feeding and other factors, the children of the women who took fish oil were significantly better at hand-eye coordination than those of the women who took the olive oil supplement.

The authors acknowledged that their sample was small, and that they could not exclude the possibility that the result was due to chance. Still, children who received prenatal fish oil did consistently perform better on all measures of development.

“These preliminary data indicate that supplementation with a relatively high-dose fish oil during the last 20 weeks of pregnancy is not only safe,” the authors concluded, “but also seems to have potential beneficial effects that need to be explored further.”
