The 2020-2025 Dietary Guidelines break down nutrition recommendations by age, though, of course some themes span across the lifespan. The best nutrition for kids follows along a similar vein as that for toddlers -- eat lots of fruits and vegetables, aim for enough dairy or soy (or alternative) to ensure enough calcium and vitamin D intake, and keep the sugary drinks to a minimum (ideally none at all). Of course what kids should eat and what they willingly choose is often not the same. As parents our job is not to force them to eat but rather offer the healthy stuff often and in different ways and be sure to model the habits we'd like our kids to adopt. In the end, that is more likely to lead a child to willingly choose fruits and vegetables, than forcing them to do so.
