About this food

How to think about Grains & Starches: Cornmeal is worth a closer look - Grains and starches are usually relatively low in potassium and phosphorus, making them a sensible base for a CKD diet. Watch whole-grain and some processed grain products, which can carry more phosphorus.

Nutrient insight

Cornmeal's phosphorus is the top contributor (80% of its limit). Source matters: animal phosphorus absorbs at 60-80%, additive phosphorus near 100% - the same number can mean very different real loads.
