Arugula
Conventional nutrition information suggests lots of dark leafy greens like spinach and kale. While these are extremely healthy foods, they are also high in potassium and therefore not recommended on a renal diet. Arugula is a great alternative. It is both low in potassium and high in vitamin K, manganese, and calcium. It also contains nitrates, which are known to lower blood pressure, another important consideration for people with kidney disease.
One cup (20 grams) of raw arugula contains:
- Sodium: 6 mg
- Potassium: 74 mg
- Phosphorus: 10 mg
