Here are few tips to follow recommended by Jeanne Cullen, MS, RD, CD, CDE.

Try to consume refined grains as opposed to whole grains like whole wheat. Look for “refined flour” on the label. Cream of wheat and processed cereals like corn flakes are all good bets so are breads that don’t use whole grains.

Fats like oils, butter and margarine are low in potassium as are cheeses that contain less than 5 grams of fat per serving. Fish, meats, vegetables and fruit all contain a decent amount of potassium. It is best to avoid certain fruits like honeydew, bananas, apricots, citrus fruits, kiwis and watermelon as well as veggies like beets, artichoke hearts, leafy greens, mushrooms, tomatoes, winter squash, yams and potatoes. Meats and fish can be consumed but they need to be limited to just one or two small servings each day. Cullen recommends that you can “leach” potassium out of your vegetables by soaking them in water in lots of water for several hours and then cook them in lots of water.

In addition, egg whites, limited amounts of nuts and nut butters, berries, crackers, certain vegetables and certain grains like processed flours and popcorn can be consumed regularly on a low potassium diet.

These are just some general guidelines to follow but since a low potassium diet is fairly complex, I encourage that your husband works with a renal dietitician to best formulate a nutritious, safe and satisfying meal plan.

If you don’t mind, would you elaborate more on your diet? There is so much information right now on safe and unsafe fish. Whether it is because of mercury levels or unsafe fishing practices, I know that many of my friends have been more reserved in eating fish than other meat and poultry because of these reasons. Many of us would be eager to learn more about how you accomplished such an amazing endeavor.
