Childhood obesity, rapid growth linked to pregnant moms eating lots of fish

"Women who ate fish more than three times per week when they were pregnant gave birth to children with higher BMI values at 2, 4 and 6 years of age compared with women who ate fish less. High maternal fish intake during pregnancy also was associated with an increased risk of rapid growth from birth to 2 years and with an increased risk of overweight/obesity for children at ages 4 and 6 years compared with maternal fish intake while pregnant of once a week or less, the results indicate. The magnitude of the effect of fish intake was greater in girls than boys.
"Contamination by environmental pollutants in fish could provide an explanation for the observed association between high fish intake in pregnancy and increased childhood adiposity," the authors write. However, the authors note that while they collected information on the consumption of different fish types, they did not have enough data to distinguish between species, cooking procedures and the water source of the fish from rivers or the sea."
