About this food

How to think about Legumes & Nuts: Tofu is worth a closer look - 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 sodium is the top contributor (144% of its limit). Sodium drives blood pressure and swelling, and most CKD patients limit it - watch hidden sodium in sauces and cured products.
