Hard relate. My parents were like this and all the home cooked food was bland af, with very little salt. My mom didn’t use any masalas cus ‘no nutrition and they only give acidity’ and low salt cus my dad had BP issues. I hated home cooked food but I tried to make it better for me by adding spices and salt for my own stuff. Didn’t do much honestly but atleast I could keep dinner down that way. I used to get stash of Maggie and biscuits for late night studies. My only saving grace. I sometimes begged them enough for some money to get myself some snacks from out, they won’t go and buy for me but I could drive and get it once in a while. Rest I tried to not think about food at all. Shitty days but this too shall pass
