The foods we eat can influence the health of our kidneys so eating foods that are supportive is essential to our wellbeing. In this podcast we discuss some of these foods and their benefits.
Our kidneys do well on:
- hydrating and detoxifying foods
- low sodium and anti-inflammatory foods
- moderate protein intake
- healthy fats
Sufficient water intake helps to keep us hydrated and helps to flush toxins.
Apart from water, vegetables like cucumber are hydrating and have anti-inflammatory properties. You can also add fresh lemon to your water to support your pH balance and detoxification.
Low-sodium and anti-inflammatory foods include:
- Garlic & onions (anti-inflammatory, boost immunity)
- Turmeric & ginger (reduce inflammation)
- Berries (blueberries, strawberries, raspberries – high in antioxidants, low in potassium)
- Apples & pears (low in potassium, fiber-rich for gut and kidney health)
- Leafy greens (but watch potassium levels if you have kidney disease)
- Cauliflower and cabbage (low in potassium and rich in nutrients)
- Red bell peppers (high in vitamin C, kidney-friendly)
- Radishes (natural detoxifier)
Avoid eating too much protein and too many processed foods
Too much protein (especially from red meat) can overwork the kidneys, and processed foods often contain high levels of sodium and phosphorus.
Rather eat healthy protein sources in moderation. These include egg whites, lean chicken, and fish such as salmon, tuna, trout. Quinoa is also a healthy source of protein.
Healthy fats include:
- Olive oil
- Avocados
- Nuts (preferably unsalted)
Foods to avoid if you have kidney problems or kidney disease:
High-sodium foods including processed meats, bacon, sausages, deli meats, as well as canned & packaged foods such as soup, chips, fast food.
Pickled & fermented foods (sauerkraut, soy sauce)
High-potassium foods such as bananas, oranges, potatoes, tomatoes, dairy products including cheese, milk, and yogurt, and beans & lentils which are high in potassium & phosphorus.
Sugary and processed foods such as sodas, sweets, pastries, and ice cream
Alcohol & caffeine in excess dehydrates our bodies, raises our blood pressure and can stress our kidneys.
