Hi Everyone!
Today I'm going to show you something that I have done a lot of research on and believe it to be true. Maybe, it is something some of you already know about but for me it's new and a life saver for Mr. M's Kidney.
It is a soaking method to remove phosphorus and potassium. In most of the sites I have checked, they do agree that Cooking in water, pressure cooking and cooking in a microwave oven reduced potassium levels. All food groups were tested and both Phoss and Potas were reduced. However, on the NIH.gov site 20 different foods were tested by taking deionized water 5 to 1 ratio.( I have a water filter system that does deionize the water, however, you can used distilled water. You want water that has no minerals.) The results to the soaking method showed foods resulted in a reduction in potassium and phosphorus.
Potassium reduction in beef, green leafy vegetables, and grains was
40-49%; in chicken, fish, and nonleafy vegetables 30-39%; and tubers
10-20%. Phosphorus reduction in grains and beans was 30-39%; in nonleafy
vegetables 20-29%; and beef, chicken, and fish 10-20%.
This is significant for CKD.
Of course, I can't measure the amount of Phoss or Potas after soaking the food. It is quite a process I do know that it is much less and I write this down in the food journal. How is it measured in the lab? The potassium content was determined by flame photometry. The phosphorus content was determined by visible ultraviolet spectrophotometry,below.
flame photometry below.
I've made several meals using the soaking method. The best was sweet potatoes. Then I roasted them. Potatoes have to be soaked several time due to the high potassium content.Get the water boiling.

Turn off the heat once the water is boiling. Be sure to rinse after the 10 minutes.
|
Let the sweet potatoes soak for 10 minutes then repeat. Dry them off and roast in the oven.

Today I did pearl barley for a soup.
|
I didn't have quite a cup of pearl barley but it's enough.
|
|
Boil the water and remove from the heat. Then add the P. B. and let is sit for 10 minutes.
|
Rinse it with cold water thoroughly.

Pearl Barley doesn't take long to cook and this process make the cooking time even less so add it to soups or stews at the last few minutes.
I hope this info helps.Nicole
