It's been talked about before but honestly a shitty diet isn't going to be enough for SS, even in Britain its not going do anything, while yes he's being fed absolute junk with nothing good it's not as if he isn't being fed completly, SS are only going to intervene if there's strong evidence that the kid is being starved or beaten etc an they should only ever be used for such cases, I know people have spoken about how little help SS get in America an even in Britain they get little help so really unless he was being absolutely beaten an properly starved then they shouldn't be getting called away from kids who do need that help from experiencing it
Unfortunately I know just how bad this diet can get further down the line, none of my cousins 3 kids eat any fruit or veg because their mum couldn't be bothered making them if they said no an they all grew up with just as bad a diet as J has now, all 3 are teens now an have crappy health which will probably only get worse as they get older
