4. pH balance
Lemons are considered one of the most alkalizing foods you can eat. This may seem counterintuitive, as they are acidic on their own. However, in the body, lemons are alkaline; the citric acid does not create acidity once it has been metabolized.
The minerals in lemons actually help to alkalize the blood. Most people are too acidic, and lemons reduce overall acidity, drawing uric acid from the joints. This reduces the pain and inflammation which many people feel.
