@babybythesea totally agree a balanced approach is far healthier.
I do think some Uk schools/nurseries have gone WAY too far on the "healthy eating" faddiness!
When we have schools telling especially young and impressionable children things like fruit, eggs and cheese are "bad" foods we've seriously lost our way!
@canyoutoleratethis I only have one! I wasn't being snobby at all! I was recognising this stage of parenting- which if you'd read my post PROPERLY you'd see I said we all go through it
I certainly did! Compounded by my having ocd which I had a bad flare up of just after having dd. I gradually learned to relax and pick my battles! ESP as dd was the absolute opposite of me! Dirt magnet who'll eat anything and everything! The afternoon when she was 18 months and I caught her eating a spider I basically gave up! 
She is now 20, slim, relatively healthy (barring her genetic disability) and with a healthy approach to food and nutrition.
I am very interested and fairly knowledgeable on healthy eating myself (even if I don't practise it! I'm currently losing weight myself - but the gain is at least partly due to disability and the meds I'm on which affect metabolism and water retention etc) so I'm not being dismissive just offering a bit of a reality check!
I had gd while pregnant even though I'm not a sweet toothed person and was a size 8 prior to pregnancy, but then all the women in my family have had gd with every pregnancy regardless of prior health. I was told that this COULD increase dds risk of developing diabetes herself and so it was best to "limit" processed sugar in the first year. As a result she had absolutely no processed sugar in that first year - that was my pfb moment diet wise.
Of course it didn't last and by 2 she was as much a fan of chocolate, cake and ice cream as any toddler though she still wasn't given such things very often.
As parents become more experienced and more confident as parents they move past the pfb stage (usually not all) and learn to have a more balanced approach to parenting and the decisions one makes as a parent.
I didn't deserve being torn into like that!
