Ever reach for a Coke when nausea strikes?
Many people swear by a glass of cola to ease nausea, while others point to its sugars and minerals for combating traveler's diarrhea or dehydration.
There's no robust scientific evidence supporting cola as a remedy for gastrointestinal issues or dehydration. In fact, Diet Coke may even trigger diarrhea in some cases. If you're feeling nauseous, a small sip of cola won't hurt, but don't count on it as a reliable fix.
Belief can be powerful—if you truly think cola helps, the placebo effect might provide some relief.
