Lowering Potassium in Potatoes
Certain high-potassium foods, such as potatoes, can be soaked in water to reduce their potassium content for people on the kidney diet.For years, renal dietitians have instructed patients on low-potassium diets to cut up and leach or soak potatoes to reduce the potassium load.For the most effective potassium removal, potatoes must be cut into small pieces, sliced thin or grated.If boiled at least 10 minutes in a large pot of water, potassium is reduced by at least half the original amount.These potatoes will still contain 100 to 200 milligrams of potassium in a 1/2-cup serving so people on a low-potassium diet are encouraged to pay attention to portion control.A small order of French fries from five major fast food chains ranges from 470 to 510 milligrams of potassium. .

Certain Potato Preparation Guidelines For Kidney Dialysis Patients
Shelley Jansky, PhD, and Paul Bethke, PhD, both of the United States Department of Agriculture – Agricultural Research Service and University of Wisconsin-Madison Department of Horticulture, utilized samples of potatoes that had been shredded as well as potatoes that had been diced into 1 cm cubes.Those with compromised kidney function can decrease their mineral intake while still taking advantage of the other nutritional qualities of potatoes by boiling them, thinly sliced.“Our study offers information about the nutritional quality of potatoes and the effects of cooking on the contents of mineral nutrients,” the authors conclude. .
How Do I Leach Out Starch For Making Fries And How Can I Make
Chilling the water or adding ice is a method that helps the cells seal up and makes for a crisper fry when blanched.By the way, this excess starch, when captured, makes an excellent thickener for soups and is gluten free too! .
