A new study challenges popular belief that fish consumption during pregnancy can contribute to ASD in children. Analyzing blood samples in one of the largest longitudinal studies to date, researchers found no links between mercury levels in mothers and autistic traits in their offspring. Surprisingly, the only adverse effect of mercury was noted in children's poorer social skills if the mother did not consume fish at all, especially in girls.
Increasing fish consumption could help to lower the risk of developing Parkinson's and other neurodegenerative diseases, researchers report. The study reveals the protein parvalbumin can help to prevent the formation of alpha synuclein.
According to researchers, children who eat fish at least once a week score four points higher on IQ tests and sleep better than those who consume fish less frequently, or not at all.
