Fruits that are heavily alkaline include watermelon, cantaloupe, mangoes, pears, grapes and passion fruit. Dried fruits like dates, apricots, figs and raisins are also considered heavy alkaline foods. Apples, fresh apricots, bananas, berries and avocados all have a moderately alkaline pH of around 8.0.
Alkaline Foods. Alkaline foods should really be referred to as alkaline forming foods. Food is considered alkaline forming if food forms alkaline in the body's blood and urine. This does not mean that the food itself is alkaline: it may well be acidic. Orange juice for instance is highly acidic due to its high citrus acid content, but after being metabolized it will cause urine to become alkaline.
