Foods that are good for the kidneys should be those with low sodium and salt content. Consuming too many of these two components can cause high blood pressure - one of the common causes of kidney failure.
In addition, excessive potassium intake can also put pressure on the kidneys, forcing this organ to increase activity to filter and excrete potassium from the blood. This prolonged condition can increase blood potassium levels, posing many health risks. Therefore, to support kidney function and maintain overall health, you should prioritize choosing foods with low potassium content. You can refer to the following foods that are good for the kidneys:
1. Egg whites
Egg whites are a source of high-quality protein, suitable for people who need protein supplementation but must limit phosphorus, especially patients undergoing hemodialysis. 2 large egg whites (about 66g) contain 110 mg of sodium, 108 mg of potassium and 10 mg of phosphorus.
2. Kieu mach
Barley is also a suitable choice when it has a lower phosphorus content than many other grains, and is rich in B vitamins, magnesium, iron and fiber; half a cup of cooked barley (about 84g) contains 3.5 mg of sodium, 74 mg of potassium and 59 mg of phosphorus.
3. Cabbage
Cabbage provides a lot of vitamin K, vitamin C, vitamin B, and also has low levels of potassium, phosphorus and sodium, along with insoluble fiber that helps support digestion; in 70g of chopped cabbage, there are 13 mg of sodium, 119 mg of potassium and 18 mg of phosphorus.
4. Bell peppers
Bell peppers are also a nutritious but low-potassium food, containing a lot of vitamin C and vitamin A that help boost immunity; in 74g of bell peppers there are 3 mg of sodium, 156 mg of potassium and 19 mg of phosphorus.
5. Onions
Onions help create a natural flavor for dishes, contribute to reducing salt use, and also provide vitamin C, manganese, B vitamins and prebiotic fiber that are good for the digestive system; a small onion (about 70g) contains about 3 mg of sodium, 102 mg of potassium and 20 mg of phosphorus.
6. Radishes
Radish is a food with low potassium and phosphorus content but rich in vitamin C; 58g of sliced radish contains 23 mg of sodium, 135 mg of potassium and 12 mg of phosphorus, while 78g of cooked radish contains 12.5 mg of sodium, 138 mg of potassium and 20 mg of phosphorus.
