This is for "free sugars" though, so whole apples should not count if I got it right. Fruit juice "frees" the sugar though, so sugar in apple juice should count.
Fruits have been cultivated and bred towards greater sweetness. They are much sweeter than their natural ancestor.
indeed, not something I like. now apple doesn't feel healthy at all, more like a giant candy (i know it's still probably healthier to eat it rather than not, but I really wish there would be types which would be less sweet)
I think "healthy food" is a bit misnomer: only people can be healthy or unhealthy, while food can be nutritious or not. While health of an apple is quite a different thing (apple tree disease?)
