  • Introduction

    The best diet for kidney dialysis patients is one that is low in sodium, phosphorus and potassium. A patient on dialysis should also limit their intake of fluids. Eating a healthy diet is important because it can help slow down the buildup of waste in the body and can help ease the symptoms associated with kidney failure.

    It’s important to talk to your doctor before starting a specific dietary plan, as different diseases and medications may require different diets. Some general guidelines that apply to kidney dialysis patients include:

    • avoiding high-fat, processed and salty foods
    • limiting your intake of fruits and vegetables
    • avoiding foods that are high in protein since they can cause more strain on the kidneys while they are attempting to filter out waste products from the body.

    Nutrition Basics

    Nutrition plays an important role in the health of dialysis patients. Eating the right foods can help your body get the nutrients it needs to maintain good health and to manage the symptoms that come with kidney dialysis. It is also important to stick to a diet tailored to your individual needs. Here, we will discuss the basics of nutrition for kidney dialysis patients:


    Macronutrients are the nutrients your body needs to build and maintain its tissues, produce energy and regulate bodily functions. The three macronutrients are proteins, carbohydrates and fats. It is important for dialysis patients to be aware of their macronutrient needs since their kidneys may not be able to handle too much of one type of nutrient. A doctor or dietician can typically advise on a dialysis patient’s macronutrient balance.

    Proteins are an essential macronutrient that help the body build and repair cells, as well as assist with immune system functioning. Dialysis patients should aim to get an adequate amount of lean proteins in their diet such as chicken, fish and eggs.

    Carbohydrates provide energy for the body as well as adding flavor, texture and color to meals. Healthy carb sources for dialysis patients include fruits, vegetables, whole grains and legumes like beans and peas.

    Fats help keep your skin healthy by improving skin cell structure, support proper brain development, provide energy throughout the day, absorb vitamins A D E K from the foods you eat and make you feel full longer after eating meals with fat in them. Dialysis patients should make sure they enjoy fats from healthier sources such as olives oils nuts seeds avocado’s butter etc.


    Micronutrients are vitamins, minerals, and other natural compounds that the body needs in small amounts to ensure optimal health. A balanced diet of fresh foods is the best way to get all the micronutrients you need. The best diet for kidney dialysis patients includes adequate amounts of all the essential vitamins, minerals, and other micronutrients.

    Examples of vital micronutrients include:

    • Vitamin C (found in oranges and peppers)
    • Magnesium (found in nuts and lentils)
    • Zinc (found in red meat and shellfish)
    • Folate (found in dark green leafy vegetables)
    • Iron (found in legumes)

    These micronutrients are important for a variety of bodily functions such as energy production, immune system support, hormone regulation, cell growth and repair, bone maintenance, and many more. A healthy dialysis diet should be tailored to provide sufficient amounts of these essential nutrients.

    Dialysis and Kidney Disease

    Kidney disease is a serious medical condition that can cause excess levels of waste products and fluids to accumulate in the body. Dialysis is a treatment that helps filter out these excess products and fluids from the bloodstream.

    For those who are on dialysis, it is important to have a healthy diet to ensure their body is getting the nutrients it needs. In this article, we will look at the best diet for kidney dialysis patients.

    Overview of Dialysis

    Dialysis is a type of medical treatment that helps to filter waste, salt and extra water from the body when the kidneys are no longer able to do so. People with kidney failure or end-stage renal disease often require dialysis treatments several times a week in order to maintain health.

    A dialysis diet has a few key differences from a regular healthy diet. It is highly important for those on dialysis to stick closely to their doctor’s recommendations and any dietary plan designed for them. Dialysis patients often need to limit their intake of fluids, potassium, phosphorus, sodium, and protein. Many plant-based diets may be beneficial for these conditions as well. Working closely with a healthcare provider will help ensure goals are met—and maintained—for dialysis patients with kidney diseases.

    Kidney Disease and Diet

    Kidney Disease and Diet are closely related, as maintaining the health of your kidneys is essential to staying well. Eating a balanced diet is important for maintaining healthy kidney function. Your diet should be tailored to your particular type of kidney disease and dialysis modality, as well as other health conditions you may have.

    It is important to note that depending on your stage of kidney disease and/or modality, certain nutrients may need to be restricted or increased in your diet. It is recommended that you discuss any changes in your diet with a nutrition expert or dietician who can make sure that you get the nutrients you need without putting too much stress on the remaining functioning kidneys if applicable.

    The best diets are those that are low in sodium, sugar and fat, with an emphasis on nutrient-rich fruits, vegetables and lean proteins. Eating plenty of fresh fruit and vegetables helps maintain fluid balance as well as slow down the rate at which damaged or overworked kidneys lose their ability to function optimally.

    Dietary Guidelines for Dialysis Patients

    Kidney dialysis patients must follow a special diet to maintain their health. It is very important to ensure that dialysis patients get the right nutrients to strengthen their bodies and reduce the chances of further complications. To that end, there are certain dietary guidelines that should be followed.

    Let’s take a look at what those guidelines are:


    Protein is an essential nutrient for all people, but it is especially important for dialysis patients. Protein helps your body heal and rebuild tissue, and it helps to prevent malnutrition.

    For kidney dialysis patients, the guideline is to consume a protein-rich diet – usually around 1 gram of protein per kilogram of body weight per day. This recommendation can vary depending on a patient’s individual needs and medical advice from their doctor or dietitian.

    Sources of high-quality protein include:

    • Lean meats
    • Fish
    • Tofu
    • Legumes
    • Nuts
    • Low-fat dairy products
    • Egg whites

    To ensure you are getting enough protein in your diet each day, your healthcare provider may have you track your food intake or supplement with added protein powder.


    Carbohydrates are your body’s main source of energy and it is important to include a sufficient amount of carbohydrates in your diet if you are on dialysis. In a dialysis diet, 45% to 60% or more of your total daily kilocalories should come from carbohydrates. Since most carbohydrates contain the same amount of calories per gram, aim to get at least 225 grams per day.

    Common sources of carbohydrate in a dialysis diet include:

    • Breads and cereals
    • Fruits
    • Starchy vegetables
    • Dairy products like milk, yogurt and cheese

    Make sure to choose complex carbohydrates such as whole-grain breads and cereals and low-starch vegetables such as broccoli, cauliflower, peppers and green beans over simple carbohydrates such as candy bars or sugary drinks.


    Fats are an important part of a kidney dialysis patient’s diet and should be consumed in combination with other macronutrients like carbohydrates and proteins. Fats provide the body with essential fatty acids and energy which helps the body to function at its best. Fats also help your body absorb fat-soluble vitamins like A, D, E and K.

    For optimal health, kidney dialysis patients should eat polyunsaturated fats (e.g. omega 3s) such as fatty fish, nuts, seeds and vegetable oils instead of saturated fats such as butter or lard. Patients should also keep their total fat intake to below 30-35% of their daily caloric intake and reduce their consumption of trans fats altogether. Saturated fats can raise cholesterol levels which can put an additional strain on a patient’s kidneys so it is important to limit these as well.


    For dialysis patients, adequate hydration is essential. On average, 2 to 3 liters of fluid may be consumed each day for those on dialysis. Fluid intake should be carefully monitored as too much water can lead to swelling and weight gain that can cause symptoms such as shortness of breath, fatigue, and confusion.

    For those on hemodialysis, the dietitian will advise limiting fluids and sodium due to their effects on blood pressure; a diet low in sodium is typically recommended across all dialysis patients. If a patient is not able to eat or drink enough fluids by mouth it may be necessary to receive additional fluids through an intravenous (IV) line during their treatment.

    Dialysis patients should talk to their healthcare provider about the best way to hydrate themselves, and consider discussing extra options if they struggle with swelling or weight gain due to excessive fluid intake.

    Vitamins and Minerals

    Vitamins and minerals are essential components of a healthy diet. Dialysis patients need to ensure that they’re getting enough of them to help their bodies work properly and ward off any malnutrition. For people who undergo dialysis, it is important to focus on foods that are high in:

    • Calcium: Dairy products, dark leafy vegetables, tofu, sardines and fortified foods such as soymilk.
    • Vitamin D: Egg yolks, fortified milk or yogurt, fatty fish such as salmon or tuna.
    • Iron: Red meat, poultry, oysters, legumes (beans), dark green leafy vegetables such as kale and collards, enriched breads and cereals.
    • Magnesium: Nuts and seeds (such as almonds or sunflower seeds), legumes (beans), dark green leafy vegetables (such as spinach), whole grains (such as brown rice).
    • Potassium: Legumes (beans), fresh fruits such as bananas and oranges, avocados and potatoes.

    Vitamins B1 (Thiamin), B2 (Riboflavin) , B6 , B12 , A , C , E , K and Folate should also be monitored for proper levels for optimal nourishment for dialysis patients. Talk with your doctor to learn if you need additional supplementation of vitamins or minerals in order to meet your daily nutritional needs.

    Sample Meal Plan

    Eating a healthy and balanced diet is important for anyone, but it is especially important for those who are undergoing kidney dialysis. Dialysis patients must watch their intake of proteins, salts, minerals, fluids, and other nutrients. With a properly planned diet, they can reduce the risks and complications that come with chronic kidney disease.

    To help dialysis patients, here is a sample meal plan:


    Breakfast is an important meal for kidney dialysis patients because it provides them with the glucose and protein their bodies need to start the day. Breakfast meals should include protein-rich foods like scrambled eggs, lean meats like chicken or turkey bacon, and whole grains such as oatmeal or whole-grain toast. Other breakfast items such as yogurt and fruit smoothies can also be included in a diet plan.

    Patients should avoid sugary cereals, processed items such as frozen pancakes, sugary drinks and high-sodium foods such as crispy bacon or sausage links. Eating a healthy breakfast will give patients the energy they need to make it through their dialysis session and get on with their day.


    Lunch is a critical part of any meal plan, especially for kidney dialysis patients. It’s important to include foods that are high in protein and low in sodium and phosphorus. Examples of meals that could be included are:

    • Grilled chicken breast with brown rice
    • Tuna salad on whole wheat bread
    • Lentil soup with a side of roasted vegetables
    • A turkey sandwich with avocado

    Additionally, it is recommended to limit or avoid processed foods such as hot dogs or pre-made sandwiches as these are typically high in sodium and low in the nutrients needed for good health. Fruits and vegetables can also be included at this time; ideally fresh fruits and vegetables are chosen but frozen options can also be used when fresh is not available. Hydration during lunchtime is important too; try to include some water or unsweetened tea with each meal!


    Dinner for kidney dialysis patients should include lean proteins, healthy carbohydrates, fruits and vegetables. A sample dinner option might include grilled chicken breast with steamed vegetables, a green salad and a piece of whole wheat bread.

    Lean protein sources could also include fish such as salmon, tuna or mackerel; white-meat poultry such as turkey or chicken; soy products such as tofu; and legumes such as chickpeas, lentils or black beans. Healthy carbohydrate sources can come from fruits and vegetables like potatoes, sweet potatoes, squash, corn and peas. Whole grain breads and cereals are also beneficial. Baked fish with seasonings is also an excellent choice to provide variety in the diet. Fruits can provide fiber while providing natural sweetness which can help satisfy cravings for sweets without jeopardizing health.

    Most importantly, all meals should be low in sodium to prevent fluid retention and high blood pressure.


    Kidney dialysis patients need to take special dietary precautions in order to support their overall health. In conclusion, kidney dialysis patients should focus on a balanced diet that is low in fat and sodium, yet rich in essential vitamins, minerals and proteins. Additionally, hydration is also key for these individuals; drinking at least 6-8 glasses of water each day can help keep them healthy and hydrated.

    By following the dietary guidelines outlined here, kidney dialysis patients can maintain their health and reduce the risk of further complications related to their disease:

    • Low in fat and sodium
    • Rich in essential vitamins, minerals and proteins
    • Drink at least 6-8 glasses of water each day
