There is often misunderstanding of lemonâs pH outside the body versus inside the body. Letâs get this straight and expound on 10 benefits of regularly taking lemon juice with warm water (note: NOT equal to lemonade!). Outside the body, lemon juice is acidic (pH is below 7). This is a non-issue.
A pH of 7 or less is considered acidic, which means all juice is acidic, but some is better-tolerated than others. For reference, citrus fruits such as lemon juice has a pH of 2.0 to 2.6, grapefruit a pH of 3 to 3.8 and orange juice a pH of 3.3 to 4.2, while apple juice has a pH of 3.4 to 4 and milk a pH of 6.3 to 6.6. Acidity in juice creates a sour taste, though the sourness is often offset by the natural sugar in juice.
