Summary

This study looks at whether eating yogurt every day can help children think better and have a healthier gut. Researchers will give 60 kids, ages 7 to 9, either fruit juice or yogurt smoothies for four weeks. They will measure memory, focus, brain activity, and gut bacteria to see if yogurt makes a difference.
