Mint

Many people believe that mint species like peppermint and spearmint might relieve stomach issues. However, there is some proof that some mint varieties could contribute to heartburn.

According to studies, peppermint lowers LES pressure and may contribute to heartburn. Peppermint may soothe an upset stomach, but it can also make heartburn worse. The same peppermint side effect that helps soothe your stomach also relaxes the lower esophageal sphincter (LES), allowing stomach contents to leak up into your esophagus. Although mint may cause GERD symptoms, this only seems to be a problem for a small percentage of GERD sufferers. You might want to cut out mint products from your diet if you have heartburn after drinking them to see whether this relieves your symptoms.
