You may not need a pill or tablet to relieve your indigestion. A teaspoon of straight olive oil could do the trick. Research from Bastyr University in Washington has found it can soothe an upset stomach in 15 minutes. That’s because olive oil contains anti-inflammatory compounds that aid digestion enzymes and bile. In fact, consuming 2 tablespoons of olive oil a day – like in salad dressing or on roasted vegetables – can help alleviate chronic gastrointestinal pain in 3 weeks.
