Research is confirming that children conceived between June through August are likely to score lower on cognitive tests. Leading researchers suggest that the cause is seasonal pesticides and nitrates, which are detrimental to brain development. The researchers found that test scores for math and language were distinctly seasonal with the lowest scores received by children who had been conceived in June through August.
Does that mean children conceived during these months may not be as smart as they could have been? Yes. "The fetal brain begins developing soon after conception. The pesticides we use to control pests in fields and our homes and the nitrates we use to fertilize crops and even our lawns are at their highest level in the summer," said Paul Winchester, M.D., professor of clinical pediatrics at the Indiana University School of Medicine. "Exposure to pesticides and nitrates can alter the hormonal milieu of the pregnant mother and the developing fetal brain."
So lets all do the world a favor and go organic, because we already have enough stupid people in the world!
