Bananas do contain some potassium (330mg per 100g), but they are also high in carbs at 20g of carbs per 100g. Potassium is an important electrolyte needed for healthy functioning of the body.
Topic Overview
| Food (no table salt added) | Serving size | Potassium (mg) |
|---|
| Spinach | ½ cup | 420 |
| Sweet potato, baked | 1 potato | 450 |
| Tomatoes, canned | ½ cup | 200–300 |
| Tomato, fresh | 1 fruit | 290 |
Low-potassium foods (less than 50 mg per serving):1 ounce of cheese (20 to 30)
MOST COOKING METHODS DESTROY THE NUTRIENTS IN POTATOES. While boiling potatoes does cause a small loss of water-soluble nutrients like vitamin C and vitamin B6, the white potato retains most, if not all, of its potassium and dietary fiber regardless of cooking method, such as baking, boiling, or frying.
The initial potassium content in canned legumes was low enough, 100 mg/100 g edible portion, but with the application of a subsequent culinary treatment, it was possible to leach up to 95% of the potassium to almost negligible values.
Potassium is a mineral in your cells. It helps your nerves and muscles work as they should.

| French fries | 3 oz | 470 |

Loading up on pasta and rice may not be something many diet books recommend, but both are pretty low on potassium. They contain between 30 and 50 mg per half-cup. However, you should watch what you put on them. Just half a cup of tomato sauce or tomato puree can contain as much as 550 mg of potassium.
Sweet potatoes also contain vitamins and minerals, such as potassium, that may help balance the levels of sodium in the body and reduce its effect on the kidneys. However, as sweet potato is a high-potassium food, anyone who has CKD or is on dialysis may wish to limit their intake of this vegetable.
White bread is typically recommended over whole wheat bread on a renal diet due to its lower phosphorus and potassium levels. All bread contains sodium, so it's best to compare food labels and choose a lower sodium variety.
In April, the Journal of the American Medical Association (JAMA) published a study that looked at whether high doses of B vitamins (folic acid, B12, B6) helped people with kidney disease due to diabetes. The study found that high doses of these vitamins were actually harmful.
In summary, coffee is an acceptable beverage for kidney disease. If consumed in moderation it poses little risk for those with kidney disease. Additives to coffee such as milk and many creamers increase the potassium and phosphorus content of coffee.
Home remedies for reducing potassium
- Reduce your potassium intake. One of the easiest ways to lower your potassium levels naturally is to reduce the amount of potassium in your diet.
- Check your salt substitutes. Some salt substitutes are also high in potassium.
- Drink more water.
- Avoid certain herbs.
Yogurt. Yogurt is a great source of calcium, riboflavin and potassium. One cup (245 grams) of this creamy treat provides you with 11% of the RDI for potassium (52). Because yogurt is a fermented food, it also contains bacteria that may benefit gut health.
Dark Chocolate Is Nutritious — and Delicious!Of course, the darker the chocolate the better, but any 70 percent dark chocolate or higher contains antioxidants, fiber, potassium, calcium, copper, and magnesium, according to a study published in the journal Antioxidants & Redox Signaling.
A: Yes, you will lose nutrients if you soak potatoes in water; the longer they soak, the more you lose. Potatoes are a good source of potassium, vitamin C and some B vitamins, and a portion of these water-soluble nutrients will leach into the water.
Soak raw potatoes in a container for up to four hours. The potatoes should be fully submerged to prevent oxidation and discoloration. After four hours, the potatoes should be rinsed with cold water. Chopping, cutting or otherwise slicing the potatoes will excrete more starch.
Although egg yolks are very nutritious, they contain high amounts of phosphorus, making egg whites a better choice for people following a renal diet. Egg whites provide a high quality, kidney-friendly source of protein.

Tomatoes are considered a high potassium fruit, but their form can make a huge difference (1 cup servings): tomato paste 2455 mg. tomato puree 1065 mg. tomatoes, fresh 400 mg.
Potatoes are very high in potassium. Avoid baked potatoes or potatoes cooked in a microwave because all of the potassium stays inside the potatoes. Avoid scalloped and instant mashed potatoes as well as French fries. Peeling, cutting and soaking potatoes in water overnight leaches out some of the potassium.
Potatoes: One single baked potato (with the skin on) can deliver over 1,000 milligrams of potassium—which is more than twice what a single small banana boasts.
You can control the amount of
potassium you get in your diet by being aware of which foods are low or
high in potassium.
