About this food

Tofu sits in the Legumes & Nuts group. 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.

Phosphorus at 23% is the highest item. Additive phosphorus in processed foods absorbs best; naturally occurring phosphorus is more controllable.
