What is the primary reason for the introduction of mashed or pureed fruits to an infant’s diet by 6 months of age?

Introducing mashed or pureed fruits to an infant's diet by 6 months of age primarily serves to enhance iron absorption. At this stage, infants begin to transition from a solely liquid diet primarily consisting of formula or breast milk to solid foods. Fruits are rich in vitamin C, which plays a critical role in increasing the absorption of non-heme iron from plant-based foods. This is particularly important since infants have higher iron requirements as they grow, especially after the age of 6 months when iron stores from birth begin to decline.

Incorporating fruits not only helps in meeting their nutritional needs but also supports the overall introduction of diverse flavors and textures, promoting healthy eating habits as they develop. While fiber, sweetness, and the potential to replace formula are valid considerations, they do not address the primary concern of enhancing iron absorption in growing infants.
