About this food
Peanut butter is a common member of Legumes & Nuts. 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. This helps when choosing similar foods.
Nutrient insight
Potassium is the highest of the three at 37%. With reduced kidney function, blood potassium can rise, so spread high-potassium foods across the day rather than in one large serving.
