Oatmeal (Porridge)

Potassium: ModeratePhosphorus: HigherSodium: Lower

The bottom line

Soluble fibre and steady energy, but oats and especially oat bran sit high for phosphorus — and milk on top spends potassium too.

A healthier swap

Corn or rice-based cereals on phosphorus-tight days; make porridge with water or a lower-phosphorus milk alternative.
