FRIDAY, MARCH 20, 2020 (HealthDay News) – Tips for eating fish during pregnancy have been overturned over the years. Now, a new study shows that the benefits of eating fish regularly during pregnancy outweigh risks.
Fish is a major source of omega-3 fatty acids, which are important for the developing fetus. But some fish – such as swordfish, sharks and mackerel – may contain high levels of mercury, which can cause nerve damage.
The new study included 805 mother and child pairs in five European countries. During pregnancy, women were asked about their fish consumption and tested for mercury exposure.
When their children were 6 to 12 years old, their metabolic health was assessed. Metabolic health includes factors such as waist circumference, blood pressure and cholesterol levels.
Researchers at the University of Southern California (USC) found that babies whose mothers ate fish one to three times per week during pregnancy were more likely to have a better metabolism than those whose mothers ate fish less. Once a week during pregnancy.
But benefits diminish if their mothers eat fish more than three times a week during pregnancy, according to research published online on March 16. JAMA network open.
"Fish is an important source of nutrition, and it should not be avoided," said Dr. Leda Chatzi, assistant professor of preventive medicine.
