Sharing is caring!

Are you looking for a tasty way to add more nutrients in your diet while also delighting your taste buds? Then these renal diet smoothie recipes are for you!

Smoothies are perfect for a quick breakfast on-the-go or a snack to make sure you have reached your nutritional needs for the day. 

In this article we will explore what ingredients are appropriate for chronic kidney disease (CKD) and dialysis, the benefits of smoothies, offer tips on how to enjoy smoothies according to individual needs, and explore some pre-made nutrition drink options. 

Understanding the Importance of Potassium and Protein in the Renal Diet

The kidneys regulate how much potassium is in your body. When kidneys aren’t working properly, excess consumption of potassium can’t be excreted and can build up in the blood.

Potassium needs are individualized. Those with CKD may not need to limit potassium intake. However, those that have very low kidney function or on dialysis may need to follow a low potassium diet. 

Choosing low potassium smoothie ingredients will be important.

Protein needs vary as well depending on the stage of CKD. A low protein diet is recommended for those not on dialysis to slow progression of the disease. 

Dialysis requires a high protein intake due to losses during treatment. High protein food choices are beneficial and smoothies are a great way to get additional protein.

The Role of Smoothies in a Renal Diet

Smoothies enhance kidney health and overall health by providing various benefits such as: 

Hydration: usually made with milk, water or ice which provides fluid

Vitamins and Minerals: packed with healthy ingredients provides a great source of essential nutrients

Fiber: adding whole fruits and vegetables instead of juices to smoothies increase the fiber content to keep you regular, improve cholesterol levels, and keeps you feeling full.

Protein: adding high protein foods or powders to smoothies can help meet daily protein needs and help regulate blood sugar levels

Antioxidants: using various fruits and vegetables in smoothies provide beneficial sources of help ride free radicals

Convenience: a delicious smoothie makes a quick and easy breakfast or snack to enjoy or take with on the go!

Balanced meal: smoothies offer protein, carbohydrates, healthy fats provide a well rounded nutritious meal

Selecting Low Potassium Fruits and Vegetables

Depending on potassium needs, the following charts can help you select the best fruits and vegetables to add to renal diet smoothies.

Protein Sources for Renal Diet Smoothie Recipes

Smoothies can be a easy way to get additional protein. The recommendation for CKD is a lower protein diet with plant sources of protein. 

Plant-based proteins for smoothies:

Silken tofu

Nut butters: peanut, almond, cashews

Seeds: chia, hemp, flax, sunflower

Powders: pea, rice, hemp

Dialysis requires a high protein diet and smoothies are a wonderful way to add more protein to your daily intake.

High protein choices in smoothies for dialysis:

Whey protein powder: look for no added phosphate in the ingredients 

Yogurt: regular or greek yogurt

Milk: Cows milk

Any plant sources of protein listed above

Choosing the right protein powder

Protein powder can have some added ingredients that the kidneys aren’t able to process easily. For CKD, it likely isn’t necessary to consume protein powder due to low protein needs, but if it’s difficult to get adequate protein in, protein powders can be help

When looking for protein powders on dialysis, be sure to look for one that has at least 20 grams of protein, no added phosphorus, and 20% or less potassium. 

Controlling Fluid Intake in Smoothies

Dialysis may require a fluid restriction as the kidney function declines and produces less urine. When enjoying smoothies on dialysis, it’s important to count the smoothie volume as part of your daily fluid allowance. 

Portion size will need to be adjusted and smoothie size should be 8 ounces or 1 cup. 

Any extra smoothie can be placed in an airtight container in the freezer and enjoyed the next day.

Blending Tips for Renal Diet Smoothie Recipes

To get the best results for smoothies, it’s important to have a high speed blender.  This allows the ingredients to incorporate well and blend frozen ingredients with ease. 

If you don’t have a high speed blender, you may need to chop up the fruit into bite sized pieces in order to blenderize without issue. This will save you time and be less tough on your blender. 

I recommend adding the base ingredients to the blender first, which is liquids, then add the fruits and vegetables, protein, and finally the add in ingredients last. 

For smoothie bowl, which results in a thicker product, you can add less liquid. Pour into a bowl and eat with a spoon. Smoothie bowls would be a great option for those on a fluid restriction.

What about Pre-made Protein Smoothies and Supplements?

Most of the pre-made smoothies and supplements have added ingredients such as potassium, sodium, and phosphorus. It’s best to make smoothies from home, but if you need a grab-and-go supplement on occasion, these are what I recommend:

For CKD:

For Dialysis:

Renal Diet Smoothie Recipes

For higher protein smoothie, add vanilla protein powder to any of the smoothie recipes. I like Orgain or Bob’s Red Mill. You may need to add more milk if you plan to use protein powder.

I recommend Silk almond milk in these recipes because it doesn’t have any added phosphates.

For each smoothie, blend ingredients together in a high-speed blender and enjoy! All recipes serve 1.
