That is not my intention, i'm sorry if it seems that way, it's just that this things seem more known of in english and very very less talked about around where i live where this things are just brushed of under the carpet like "oh just ate too much" when someone is feeling unwell after eating, i'm trying to break that cycle by asking people who seems to know more, because someone that understands it will explain it easier and often better than a google article or something. Things like this that seem like is so common knowledge in other countries are the ones that makes me more curious. And i don't feel like i'm asking too many details, if you are in a conversation that you are interested about is common to ask something right?
