Try Kimchi, it's fermented cabbage/veggies/spices mixed together. Very strong taste and some people think it has an overpowering flavor but it is extremely good for your gut, it will help flush out bad bacteria, stimulates healthy bowel movement, cleans your gut out and will help you lose weight if eaten every day. Whenever I eat it I feel better the next day, far less bloated and never constipated. The Koreans eat Kimchi as a side dish all the time with their meals for this very reason.
