Making healthy choices is usually not a top priority for children ( or some adults either). People who refuse to see the faults of the white stuff really shit me but it’s their health, eh? And by white stuff, I mean refined foods like white flour, pasta, bread, rice and sugar.
I do try to eat less sugar but that doesn’t mean I never have it or the other whiteys (and sometimes that shits me but nobody’s perfect). Thankfully, I raised my son on wholemeal bread so when he gets white bread he knows it’s a “treat”, kind of like a chocolate bar. He also readily eats brown rice, wholemeal baking and pasta sauce with vegetables. But aside from the bread, he didn’t always accept the healthier options (wholemeal or vegetables either). At first, I had to be a bit sneaky about it. My advice is to ease into a change and don’t ban the white stuff for good. I used to think moderation was unachievable but my choices seem to sway towards that notion these days.
