What Is a Renal Diet? Benefits, Meal Planning and Recipes

Introduction

A renal diet is a specialized diet plan tailored to managing kidney disease. The goal of a renal diet is to limit the amount of waste products in your blood to prevent further damage to the kidneys. A renal diet typically limits proteins, sodium, phosphorus, and potassium, and encourages foods that are low in fat and rich in essential vitamins and minerals.

What Foods to Eat and Avoid on a Renal Diet

When following a renal diet, it’s important to be mindful of what you’re eating, as certain foods may worsen your symptoms. Here’s a breakdown of what to eat and avoid when following a renal diet:

Proteins

Protein-rich foods should be limited on a renal diet due to their high phosphorus content. Good sources of protein include eggs, fish, poultry, and tofu. Red meat, dairy products, and organ meats should be avoided due to their high phosphorus and potassium levels.

Carbohydrates

Carbohydrates make up the bulk of your diet when following a renal diet. Whole grains, fruits, vegetables, and legumes are all good sources of carbohydrates. Refined carbohydrates such as white bread, white rice, and sugary snacks should be avoided.

Fats

Healthy fats such as olive oil, avocados, and fatty fish should be included in a renal diet. Unhealthy fats such as trans fats and saturated fats should be avoided.

Sodium

The average person should consume no more than 2,300 milligrams of sodium per day. However, those with kidney disease should limit their sodium intake to 1,500 milligrams or less per day. Processed foods, cured meats, and canned soups are high in sodium and should be avoided.

Potassium

Potassium is found in many fruits and vegetables, so it’s important to be mindful of how much you’re consuming. High-potassium foods to avoid include bananas, potatoes, tomatoes, oranges, and spinach. Low-potassium foods such as apples, broccoli, carrots, and lettuce are better choices.

Phosphorus

Phosphorus is found in many foods, but it’s especially high in animal proteins, dairy products, nuts, and seeds. For this reason, it’s important to limit these foods when following a renal diet.

Benefits of Following a Renal Diet

Following a renal diet can have many benefits for those with kidney disease. According to a study published in the journal Nutrition & Metabolism, “A renal diet has been shown to improve kidney function, reduce proteinuria, slow the progression of chronic kidney disease, and reduce the risk of cardiovascular disease.” Here are some of the other benefits of following a renal diet:

Improved kidney health

By limiting the amount of waste products in your blood, a renal diet helps to reduce stress on your kidneys, which can help to improve kidney health.

Reduced risk of heart disease

High blood pressure and high cholesterol are common among those with kidney disease and can increase the risk of heart disease. Limiting sodium and unhealthy fats in your diet can help to lower your blood pressure and cholesterol, reducing your risk of heart disease.

Lower blood pressure

Limiting sodium in your diet can help to lower your blood pressure, reducing your risk of heart attack and stroke.

Meal Planning for a Renal Diet

Meal planning is an important part of following a renal diet. It’s important to plan ahead so that you know what you’ll be eating each day. Here are some tips for meal planning for a renal diet:

Making substitutions

It’s important to find healthy substitutes for foods that are high in sodium, potassium, and phosphorus. For example, instead of using regular table salt, try using herbs and spices to flavor your food. Instead of using cheese or milk, use almond milk or coconut milk.

Portion control

It’s also important to practice portion control when following a renal diet. Eating too much of any one food can lead to an imbalance of nutrients in your body, which can worsen your symptoms.

Tips for Eating Out on a Renal Diet

Ask questions about ingredients

If you’re unsure about what’s in a dish, don’t be afraid to ask your server for more information. Most restaurants are happy to answer questions about their menu items.

Choose restaurants that offer healthy options

Look for restaurants that specialize in healthy dishes such as salads, wraps, and grain bowls. These types of restaurants are more likely to have menu items that are suitable for a renal diet.

Avoid high-sodium menu items

Be mindful of menu items that are high in sodium, such as soups, sauces, and processed meats. Opt for dishes that are grilled, baked, or steamed instead.

Read nutrition labels

Be sure to read the nutrition labels on all packaged foods to check for added sodium. Look for products labeled “low sodium” or “no added salt.”

Limit processed foods

Processed foods are often high in sodium, so it’s best to limit them as much as possible. Stick to whole, unprocessed foods such as fresh fruits and vegetables.

Flavor food with herbs and spices

Instead of using regular table salt, use herbs and spices to flavor your food. This will add flavor without adding extra sodium.
