fruit and vegtables

now i know all teens are fussy eaters but my teen is extra fussy, and he really needs to improve his diet as he suffers from chronic constipation and soiling on a daily basis, which i understand isn't fun for a 14 year old. but he refuses to help himself, he has given up as hes been soiling since he was 7 and doesn't see any solution, hes also unwilling to help himself as he knows the medication equals painful intestine cramps. so for 2012 i am going to change the whole families diet, i have a lot of weight to lose anyhow! I have ordered an online shop for saturday full of healthy fruit and veg, lean chicken etc, food i love but teen hates. i am hoping without his usual selection of junk food to tuck into he will have to eat something that resembles healthy but i expect his reaction will be to kick off throw a few things about, at me and cats and storm around the house. i will have to try to take a more optimistic outlook on things maybe that will change his reaction.
