About this food

Couscous 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

Potassium is the highest of the three at 3%. With reduced kidney function, blood potassium can rise, so spread high-potassium foods across the day rather than in one large serving.
