About this food

In a CKD diet, Legumes & Nuts deserve attention: Tofu - 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

Tofu's phosphorus (48%) is worth noting - especially with Natural plant source (lower absorption) as the source, since absorption differs a lot.
