Any blogs out there by folks using bentos to help manage their diabetes OR pre teens writing about making their bentos??

A lovely woman I chat with at my son's school sooooooooo needs help managing her eating - her major health problem is diabetes. She has a granddaughter who is eating poorly and getting chunky.

I am trying to spread the bento joy but so many can't imagine it doing them any good even though they see daily what it does for me.

SOOOOOOOOO I am on the look out for diabetics and preteen/teen making bentos (not mom doing it - I am also big on getting kids to do their own cooking - never too soon for life skills!).

Thanks in advance!
