Utterance: cranberry juice is very good for destroying harmful bacteria in your guts because it's very acidic . wild rice is high in fibre so it's good for your guts and it's high in protein and minerals-i think it's also tastier than normal rice . yoghurt's good because it's also rich in protein , vitamins and is also acidic . people have been making yoghurt for thousands of years and if you have it every day , your guts will be much more settled .
