It can deteriorate tooth enamel

Have you ever noticed how sensitive your teeth are after tasting a slice of lemon? This is due to the acids acting on the tooth enamel. The tooth enamel has a pH around 5.5, so it can be eroded by more acidic substances. The studies have shown that any acid below a pH of 4 can cause tooth erosion. Citric acid, malic acid (in apples and pears) and tartaric acid (in tamarind) are the worst culprits. To protect your teeth, we recommend that you drink lemon juice with a straw to minimize contact with your teeth.



It can make canker sores worse

Le canker sores (small open sores inside the mouth) are often caused by an allergic reaction. You may have them if you are allergic to acidic foods like lemon juice. The advice is to avoid it or dilute it well with water so as not to irritate any ulcers even more. There is little evidence to support the claim that lemon juice can cause canker sores in people who are not allergic, however, one study recommends avoiding acidic foods such as fruit juices and fizzy drinks when you have these injuries.

It can make heartburn, reflux, and ulcers worse

Lemon juice can irritate the stomach lining and esophagus, causing burning or acid reflux. This drink, in fact, can cause stomach acids to rise up into the esophagus, causing heartburn.

All this occurs because it activates thepepsin enzyme, responsible for the breakdown of proteins. When your digestive juices travel back to your throat and esophagus, you experience the burning sensation associated with reflux. However, studies have not been able to definitively prove that lemon acidity is responsible for this problem; however, for those suffering from disease from gastroesophageal reflux or heartburn, this drink should be avoided.

It can cause nausea, vomiting and stomach pain

Nausea, vomiting, and stomach pain after drinking lemon juice may indicate that you need to reduce your intake.
