When trying to determine whether or not cantaloupe is acidic, it is important to consider the fact that all fruit is acidic to some point. The pH scale is used to determine the relative acidity of fruits and other things with some being more acidic than others. Cantaloupe as well as other types of melons fall at around 6.5 on the pH scale, putting them in the mild range along with many other fruits.

Although cantaloupe is in fact acidic, it isn’t nearly as acidic as other fruits such as oranges or grapefruits. While it is true that cantaloupe really isn’t that acidic, those who have problems with acid reflux will probably want to avoid eating too much of it along with other more acidic foods.
