Can anyone give me a good and trusted website of the RDI for different age groups from teens to older ppl.? - teen and dirty

This is a task, and I need a website for our RDI nutrition for children and 50 years old. I looked online and there are soooooo many places, not me, I should not use it!
If I could think of a place, above all, it would be great!
Thank you =)
