what happens if we eat fish and curd together - #24380

I am really confused about something that’s been bugging me. So, I always loved eating fish, right? Like, especially grilled salmon or sushi. And then there’s this thing about having curd, which I can’t get enough of, like putting it in my smoothies or just enjoying it plain. But recently, I heard this old saying about not mixing fish and curd together, saying something like "what happens if we eat fish and curd together" is bad for your health?? I thought it was just an old wives' tale or whatever, but then I started getting nervous. After a meal with grilled fish and a side of raita (which is like buttermilk), I felt kinda off, like my stomach wasn’t happy. I even looked up my symptoms and got a bit freaked out. I just wanna know, is there any scientific reasoning behind all this? Like, what happens if we eat fish and curd together? Am I imagining things, or should I actually stay away from that combo? Would really appreciate some guidance here because I don’t wanna miss out on my favorite foods!
