About this food

Tofu is a common member of 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 helps when choosing similar foods.

Nutrient insight

Phosphorus leads at 29%. In CKD, track phosphorus intake and factor in the source (Natural plant source (lower absorption)) to judge the true burden.
