Onion + Horseradish

 I am crazy over red wine vinegar, big white onion (chopped) & horseradish in my tuna salad. My husband said it's due to the fact that I seem to be missing a stomach enzyme I always crave pickles and vinegar and ACIDIC sour foods. He has a good point. While most people chug antacids I NEED acidity. This missing enzyme runs in my family. My grandfather and mother both had their gallbladders removed.
