Salaam/Peace to all of you.
Since I started focusing on the halal and haram foods, I have been holding my ground to use foods that are symbolized as kosher and the ones that I know 100% is halal. I live in the U.S. so the supermarkets have a lot of options (vegan, kosher, vegiterian, etc).
My biggest problem is that my parents really do not care. Especially my father. He eats pork and drinks alcohol. I live in the same house with them, so I am not sure how to seperate myself in terms of foods I eat in the hosue. My mom prepares separate dishes for me when she can and we use dish detergent that is symbolized as kosher (has U on it). I can't move out because that would be considered insulting (based on the culture that we came from).

I am going to try to do my best.
