About this food

For Legumes & Nuts, Peanut butter is a typical example. 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 37% is the main consideration. Concentrated forms such as juice and dried fruit absorb faster; whole foods are gentler.
