Top 7 Natural Kidney Cleansing Foods

2. Watermelon

If plain old water is too boring, add some flavor. Watermelon is a juicy, delicious way to keep hydrated. Of course, it’s a natural diuretic, meaning it increases urine output.

A watermelon fast can make a big difference. You can choose to chow down on this fruit for a day or two, or alternatively juice it, rind, seeds and all, and consume that alone for two days. This will assist your kidneys in flushing out toxins while providing a tasty, cooling beverage.
