About Peanut Butter
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
Phosphorus leads at 34%. In CKD, track phosphorus intake and factor in the source (Natural plant source (lower absorption)) to judge the true burden.
