Is it okay to eat food with white vinegar or drink white vinegar?

My mom always cooks rice with white vinegar because vinegar helps rice won't spoil immediately. And my mom cooks food with white vinegar and most of the time I dip my fried fish or fried ham in a vinegar in a saucer and drink the remaining 2 tablespoon of vinegar of it in my saucer.
