Here's the thing MikeOxstiff - a lot of our tastes are programmed by nature (apparently). We love things that were scarce in nature - and were/are good for us only in small quantities.
The rather worrying situation we have now is that we have engineered a lot of these things that hit the wow receptors, and have them in mass amounts, and they are very bad for us indeed.
Sweets, definitely, meat in the quantities eaten in this culture - very probably.
That is why you should certainly not allow a child to just eat the things that appeal - that would be severely crap parenting.
Hopefully you, as an adult, have more sense than to follow that as an eating pattern for yourself.
Then, there is a Big Industry behind these foodstuffs.
After that, there is the whole issue of the ethics of rearing animals for consumption by humans. Our culture isn;t big on discussing ethics in public fora, and is largely supine when it comes to dissemination of information about food, hence to raise children capable of giving informed consent, you have to, largely, make a concerted effort to inform you children, as parents, because the default setting is lack of information. And the supposed "non-ideological", "neutral" position is, in fact, no such thing, but is rather filled with the ideology of a capitalist food market, that people tend to go along with because that is the default setting in our culture.
