About this food
Tofu belongs to the Legumes & Nuts category. 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 is the top contributor (29% of its limit). Source matters: animal phosphorus absorbs at 60-80%, additive phosphorus near 100% - the same number can mean very different real loads.
