What are some detox smoothies for kidney cleansing?

Can a smoothie cleanse your kidneys?

No. Your kidneys filter blood continuously. The NIH’s NCCIH reports that few human studies of detoxes and cleanses exist, most are low quality, and a 2015 review found no convincing research that detox diets remove toxins.

Cautions for people with kidney disease

NIDDK says people with chronic kidney disease may need to limit sodium, potassium, phosphorus, and sometimes protein, and that a registered dietitian can create an eating plan for individual needs. NIDDK says phosphorus occurs naturally in protein foods such as meat, dairy products and beans, and is added to many processed foods. Do not assume a smoothie is safe: ask your care team which fruit, vegetable, dairy and protein-powder choices fit your limits. Check labels for phosphorus additives (words with PHOS), and use spices and herbs instead of salt substitutes, which can be high in potassium.

Kidney stones

NCCIH notes that leafy greens and beets are high in oxalate and that people prone to kidney stones should limit them. If you have had stones, ask your doctor which foods and how much fluid suit you.

What supports healthy kidneys

• Drinking enough fluids, unless a doctor has restricted them.
• Eating a balanced diet, including fruit and vegetables.
• Keeping blood pressure and blood sugar in check, as advised by your doctor.
• Asking about supplements and herbal products before use.

If you are healthy and want a refreshing smoothie

Cucumber, watermelon, lemon and mint with water or ice make a light drink. Tufts University advises whole fruit and no added sweeteners. NCCIH also warns that unpasteurized juices can cause serious illness, especially in children, older adults and people with weakened immune systems.
