About this food
Peanut butter (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 is the same lens used for similar items.
Nutrient insight
Peanut butter's phosphorus (37%) is worth noting - especially with Natural plant source (lower absorption) as the source, since absorption differs a lot.
