Peaches are considered to be a moderately alkaline fruit because it has a pH level of around 7.5, where 7 would be completely neutral.
Other fruits which are considered to be alkaline include apples, avocados, bananas, currants, grapefruits, lettuce, and many more. Fruits that are very acidic include oranges and nectarines. These are fruits which have a very high acidity level and therefore are lower on the pH scale.
Those who have problems with acid reflux/heart burn will want to think about eating peaches and drinking peach juice because it is only a moderate alkaline and does not pose any problems for those who have issues with hear burn.
