About this food

In a CKD diet, Legumes & Nuts deserve attention: Cowpeas - Legumes and nuts are typically high in both phosphorus and potassium, so they need care. Plant phosphorus absorbs at a lower rate (30-50%), so the real load is smaller than the numbers suggest.

Nutrient insight

Potassium is the highest of the three at 56%. With reduced kidney function, blood potassium can rise, so spread high-potassium foods across the day rather than in one large serving.
