If you're prone to heartburn, or even if you've got a tough stomach—here are some tips to help stave off tummy troubles.

• Don’t eat spicy, acidic, or fatty foods or drink too much alcohol or lots of caffeinated or carbonated drinks. Limit chocolate, garlic, onions, and peppermint.
• Do sleep on your left side to avoid putting extra pressure on the stomach. Also, keep your head elevated 4 to 6 inches if you suffer from nighttime acid reflux.
• Don’t snack right before bedtime. Stop eating and drinking 3 hours before you lie down.
• Do try to get more fiber in your diet. In addition to improving your overall health, there is some evidence that getting more fiber may reduce heartburn symptoms.
• Don’t smoke. Nicotine relaxes the esophageal sphincter and increases acid production.
• Do watch your weight. Being even slightly overweight puts pressure on the lower esophageal sphincter, causing reflux. Losing just a few pounds can help.
