About Black Beans
Black Beans belongs to the Legumes & Nuts category. 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 at 18% is the main consideration. Concentrated forms such as juice and dried fruit absorb faster; whole foods are gentler.
