21 Amazing Natural Diuretic Foods

by John Staughton (BASc, BFA) last updated -

Using a natural diuretic can be an effective way to eliminate excess water in the body, and can have a number of other natural sources to detoxify the body.

What is a Natural Diuretic?

A natural diuretic is a substance or food that can help the body detoxify and eliminate excess fluids. Diuretics tend to encourage the kidneys to move additional sodium into the urine, which can subsequently pull more water into the bladder and stimulate urination. There are also a number of health conditions that may necessitate the use of diuretics, including high blood pressure, kidney stones, diabetes, and edema, among others. [1]

While there are many prescription diuretics and more formal treatments, these can have negative side effects, whereas using a natural diuretic can be effective and side effect-free. As always, however, before adding new foods or herbal supplements to your health regimen, speak with your doctor about any potential drug interactions, allergies or pre-existing health conditions.
