Summary

This study interviewed 22 pregnant women who rarely eat fish to understand their knowledge, habits, and the advice they received. The goal was to learn why they avoid fish despite its important nutrient DHA, and how they balance the benefits with concerns about mercury. The findings could help shape clearer dietary guidance for pregnancy.
