Why do infants need fiber?

Infants need fiber primarily to support healthy digestion and prevent constipation as they transition to solid foods. While their primary nutrition comes from breast milk or formula, introducing fiber-rich foods can help establish healthy eating patterns and promote gut health. Additionally, fiber can support the growth of beneficial gut bacteria, which is essential for overall immune function and nutrient absorption. However, it's important to introduce fiber gradually and in age-appropriate forms to ensure safety and digestibility.
