-
Protein needs depend on:
Your CKD stage
Whether you are on dialysis
Your age
Whether you are at nutritional risk
For example:
Earlier stages often allow moderate protein
Stages 3–5 may require lower intake
Dialysis typically requires higher protein

No. Protein is essential for muscle, immune function, and healing.
The goal in CKD is not to remove protein, it’s to eat the right amount for your stage and health status.
For many people in stages 3–5 (not on dialysis), lowering total protein intake may help reduce kidney stress. But completely eliminating protein can increase the risk of malnutrition.
-
You absolutely can get enough protein from plant sources.
Examples:
Beans and lentils
Tofu and tempeh
Peas
Nuts and seeds
Whole grains
Plant proteins generally contain less protein per serving than animal protein, which can actually help if you are on a moderate or restricted protein plan.
Research supports replacing at least 50% of animal protein with plant protein for those with CKD.
Protein and CKD

Vinegar! Vinegar is a great substitute for salt or just to spice up any plate.
Although too much of anything is not good for you, there is not a “upper limit” to vinegar intake. Renal dietitian, Lauren Levy, does not recommend drinking it but “the amount you’re going to add on a food, it will be just fine.”
-
Opt for beans and lentils!
Lauren Levy MS, RDN, CSR says both "are a really great option for kidney health or a good protein and fiber source. Some of my favorite options with beans are in things like tacos or a taco salad. I often eat them over veggies or on toast.”
She also notes that lentils can be used in comfort foods like a vegan shepherd’s pie. Watch the full kidney recipe webinar here.
-
Try chickpea salad.
Renal dietitian, Lauren Levy, says this is one swap she often recommends:
“Chickpea salad is one of those recipes that I love to work with people on because I get usually a little bit of the side eye, like I'm not quite too sure. And I get a lot of positive feedback from my patients.”
Prepare it the same way you would chicken or tuna salad, simply swapping chickpeas in place of the meat. It also keeps well in the fridge for several days.
-
A tofu scramble can be a great option.
Lauren notes that it’s a flexible recipe that can make multiple servings:
“A tofu scramble can be a great way to get some protein in… The other nice thing is this is great for leftovers and can be really good if put together as a breakfast burrito.”
It’s also an easy way to add vegetables and flavor to a simple breakfast.
-
While reduced-sodium soy sauce exists, it can still be relatively high in sodium.
Good new, there is an option. Coconut aminos!
“If you are not familiar with coconut aminos, they are a low sodium option… You do want to read the food label because just like anything, there is one brand that is higher in sodium than others.” - Lauren Levy MS, RDN, CSR
In general, coconut aminos tend to be much lower in sodium than traditional soy sauce.
-
Try cauliflower instead.
“If you have a potassium restriction and you need to worry about potatoes, you can always sub out cauliflower in place of those mashed potatoes.” — Lauren Levy MS, RDN, CSR
Mashed cauliflower works especially well in dishes like shepherd’s pie or as a side dish when you’re looking for something similar to mashed potatoes.
