In general, those with kidney disease should avoid foods with high protein, sodium, phosphorous and potassium, according to DaVita HealthCare Partners. Many fruits and berries, such as strawberries or cranberries, are recommended for those on the renal diet, but egg whites and fish are also allowed.
Red peppers are an excellent food for those on the renal diet, as they are low in potassium but high in fiber, vitamins C, A, and B6, and lycopene, explains DaVita. Cabbage is also a low-potassium food rich in vitamins K and C, and it contains free radical-fighting phytochemicals. Garlic may be an suitable substitute for garlic salt, and it also has anti-inflammatory and cholesterol lowering properties. Onions are recommended for their low potassium and high flavonoid content.
Cranberries and other berries are beneficial for those with renal disease, according to DaVita. Cranberries have the added benefit of preventing UTIs, while blueberries are rich in phytonutrients and antioxidants. Red grapes are recommended for their flavonoid content and ability to improve circulation. Egg whites are highly recommended as a protein source for those on the renal diet, as they contain all essential amino acids while containing less phosphorous than other sources. Fish is acceptable as a protein source, and it also provides heart-healthy omega-3 fatty acids.
