I hear you. When we took our baby to the US on vacation I found it really hard to find appropriate food. American baby food had added salt and sugar which is illegal to add to baby food in Norway. We have the opposite "problem". There is no way to find baby food jars with salt or added sugar. That can't be sold in the store.
I don't get why America is so against regulation like this to promote the welfare of the most previous thing in people's lives. Do corporate interests really have that much power?
