Acid reflux (also known as heartburn) is a condition that causes a burning sensation in the lower chest area. It’s caused by a small amount of stomach acid that flows back up into the esophagus.
The stomach contains hydrochloric acid which is a strong acid that helps break down food and protects your stomach from bacteria. The lining of the stomach is naturally protected from this acid but the esophagus isn’t.
The gastroesophageal sphincter which is a ring of muscle acts as a valve that allows food into the stomach but not back up into the esophagus. Sometimes this valve fails and stomach content is subsequently regurgitated into the esophagus which results in acid reflux.
If you consume too many acidic drinks and foods your body’s pH level will become acidic and can result in a condition called chronic low-grade acidosis. When your acidic levels are too high it can cause a deficiency in mineral levels such as calcium, magnesium and potassium.
Coffee has been known to trigger acid reflux because of the high levels of caffeine and acidity, especially those suffering from GERD (gastroesophageal reflux disease). Selecting a coffee that’s low in coffee acidity can decrease your chances of throwing out your body’s pH level that causes acid reflux.
