About this food

Corn grain is a common member of Grains & Starches. 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. This helps when choosing similar foods.

Nutrient insight

Phosphorus leads at 21%. In CKD, track phosphorus intake and factor in the source (Natural plant source (lower absorption)) to judge the true burden.
