Five Foods to Avoid on a Renal Diet


For those living with chronic kidney disease, many have found a pathway to health through a renal diet. NephCure Kidney International defines a renal diet as “one that is low in sodium, phosphorus, and protein.” To put it simply, a renal diet is a kidney-friendly one!

When planning your diet, it’s important to know what foods to include and which to exclude. The following will reveal just five foods to avoid on a renal diet!

  1. Avocados

Although touted as a healthy supply of Omega-3s, avocados also contain a hefty amount of potassium. In fact, one serving of this fruit packs almost 37% of potassium on a restriction diet. Thus, if you are currently living with CKD, an avocado might not be the best choice.

  1. Whole Grains

Whole grains, such as brown rice and wheat bread, have a much higher potassium level than their white counterparts. For example, white rice only has 41 mg phosphorus per serving, whereas brown rice has 81 mg phosphorus for it’s serving.

  1. Excessive Sodium

One of the best ways to have a successful renal diet is to omit any unnecessary salt from your diet.

Always check the nutritional facts when purchasing packaged goods. Try to aim for products that are described as low sodium, no sodium, or no salt added. If purchasing prepared meats, avoid all products that are pre-seasoned or preserved in a solution, as this tends to be a copious amount of excess salt.

  1. Sodas

Carbonated beverages may seem delicious, but they pack an insidious secret: there is a multitude of additives hidden in that can. In order to preserve flavor and shelf life, many sodas are packed to the brim with phosphorus. This is especially true for dark-colored sodas, as they have been found to have higher levels of the aforementioned additive.

Thus, to ensure a successful renal diet, it’s probably best to cut out any sodas. Work with your doctor to replace these drinks with better alternatives. These could be water, tea, or natural juices.

  1. Dairy

Another food group to avoid on a renal diet is dairy. This product tends to have a hefty amount of protein, which can easily overtake the daily allowance on a kidney-friendly diet. Dairy is also packed with naturally occurring phosphorus and potassium. Paired with its protein, these factors make dairy a food to avoid on a renal diet.
