About Black Beans
About Black Beans: 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. As a Legumes & Nuts item, its role in a kidney diet depends mainly on mineral content.
Nutrient insight
Potassium at 18% is the main consideration. Concentrated forms such as juice and dried fruit absorb faster; whole foods are gentler.
