Yes, this.
I'm afraid as much as some don't like it, there are people who say things like GT has where your immediate attitude is suspicion.
I don't necessarily think celebrities mentioning general things about their kids is wrong, but again, they seem to have somewhat poor boundaries, and that creates scepticism as well.
And the food thing? I think large numbers of children go through issues around food, especially if their parents are weird about food. And it can be about the environment - I've seen a little girl go from being very problematic about food at home to being fairly typical if a bit picky when in other environments, not because of "masking" or something like that, but because all the pressures the parent was creating around mealtimes disappeared.
That's not "offensive" to parents with kids who have serious food issues, it's just another thing that happens sometimes.
