A large review of clinical studies looked at how eating fish affects the health of children between ages 2 and 14. The study focused on several important nutrients, including vitamin D, iodine, and iron.
The results showed that children who ate fish had higher levels of vitamin D compared to those who did not eat much fish. While the increase was steady, it was a modest change in the overall amount of vitamin D found in their systems.
Other nutrients like calcium, iodine, and folate did not show significant changes based on fish intake alone. The researchers noted that while the link to vitamin D is clear, the actual amount of improvement might be small enough that it does not change daily health much.
Overall, including fish in a child's diet is a reliable way to support their vitamin D levels. However, other nutrients may need to come from different sources to ensure children get everything they need for healthy development.
