Get an upset stomach and here's what else you can get: bad breath. Now here's how to keep that total turn-off from happening: yogurt. Not only is it easy on the digestive system, it's excellent at reducing hydrogen sulfide in the mouth--a particularly unpleasant compound (yes, the rotten-eggs one) that can be a side effect of internal distress.

Yogurt does this the same way it does so many other good things in the body: by replenishing beneficial bacterial in your intestinal system.

Just be sure the yogurt has live active cultures, the source of those good-for-you bacteria. Not all types do, especially the highly processed, sugar-loaded varieties that might as well be sundaes. Check yogurt labels for LAC-shorthand for live active cultures--and eat about half a cup twice a day until your insides are back to normal. At least you won't have to worry about your breath while your body's rumbling and grumbling.
