If you’ve been diagnosed with kidney disease — or just want to protect your kidneys — the first step is understanding how they work.

Your kidneys filter out toxins like pesticides, heavy metals, excess sugar, and protein waste. They also help regulate blood pressure, balance minerals, and activate vitamin D.

But when they’re overloaded or damaged, common symptoms include:

• Puffy eyes
• Swollen ankles (edema)
• Itchy skin
• Foamy or dark urine
• Gout or kidney stones
• High blood pressure

Here are 8 simple foods and habits that support kidney detox and repair:

1. Bok Choy

Rich in potassium, magnesium, and detox enzymes. Low in oxalates (which can form kidney stones) and low in protein, making it gentle on the kidneys.

2. Apple Cider Vinegar (ACV)

Helps regulate blood sugar and supports kidney detox. Add 1–2 tsp to water and sip during the day.

3. Lemon Juice

Contains citric acid, which helps prevent kidney stones and alkalizes the body — good for uric acid balance.

4. Celery
