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.
The glycemic index of watermelon is between 72 and 80. Values above 55 are considered high. However, watermelon has a low glycemic load, which according to Walter Willett, M.D., is a better measure of a foodâs effect on blood sugar. This is due to the high amount of water in watermelon. Indeed, the fruit is over 90 percent water, and since water is calorie free but filling, you are likely to become satisfied from a meal containing watermelon before you ingest too many calories or too much sugar to pose health risks.
