I have periods during the day when my innards are extremely talkative. Sometimes they tell me they are hungry, other times they are just busy digesting. It's been noisy as of late. The only modification to my diet is a daily consumption of yogurt, which I have taken a liking. Also, I've been farting like a blow horn lately, yet I'm not stinky. Does yogurt change your internal chemistry? I remember when I started eating apples every day, and the mayhem they waged on my system, so I'm thinking the yogurt might be the culprit now.
