2. Bananas
Best known for their high potassium levels, bananas are a great natural diuretic. Potassium is a natural electrolyte mineral, which makes it a diuretic. It helps the body pass sodium throughout the urine, which helps to reduce the amount of fluid that you are retaining. Munch on a few bananas a day, add them to a fruit smoothie, or slice them up and put them on top of cereal to reduce your fluid retention.
