Kidney-Friendly Meals: Delicious and Safe for Your Kidneys

Having Kidney Disease… Do You Have to Avoid Salt, Meat, and Everything Else?

This is one of the biggest concerns for many kidney patients. In reality, you don’t have to give up everything. By learning how to choose foods according to your stage of kidney disease, you can still enjoy meals and live almost like anyone else.

In this article, Pattaya Dialysis Clinic will guide you in a simple way on what to eat at each stage of kidney disease. You’ll learn how to select kidney-friendly foods that protect your kidneys and prevent your condition from worsening. We’ll also share meal ideas that patients can try for tasty, safe, and kidney-friendly dining.

Kidney-Friendly Diet for Chronic Kidney Disease (Stages 1–3) 

At this stage, the disease is still in its early phase (the kidneys are still partially functioning). Many patients may not notice any obvious symptoms yet, but it’s important to start paying attention to your diet now to slow down kidney deterioration as much as possible.

Recommended energy intake:About 30–35 kcal per kilogram of body weight per day.For example, if you weigh 60 kg, your daily energy requirement would be around 1,800–2,100 kcal (calculation: 60 × 30 = 1,800 kcal/day).

1. Protein – Reduce, but Don’t Eliminate

Patients should consume about 0.6 g of protein per kg of body weight per day.For example, a person weighing 60 kg should aim for around 36 g of protein daily (calculation: daily protein in grams = body weight in kg × 0.6).

Half of the protein should come from high-quality sources such as fish and egg whites. If protein is restricted further (e.g., 0.4 g/kg), essential amino acid supplements may be recommended by your doctor.

2. Fat – Choose Healthy Fats

Limit saturated fats such as butter, pork belly, and coconut milk.Choose healthy fats instead, like rice bran oil, olive oil, or salmon in appropriate amounts.

---

3. Minerals – What to Watch Out For

• Sodium: Limit salt to less than 2 g per day (about 1 teaspoon). Avoid pickled foods and dried fruits with high sodium content.

• Phosphorus: Avoid foods high in phosphorus, such as beans, dairy, egg yolks, sesame seeds, and coffee.

• Potassium: At this stage, restriction is usually not necessary as the kidneys can still excrete potassium well. If your doctor reports high blood potassium, start limiting intake. Safe fruits include grapes, rose apples, pears, and peaches. Fruits to avoid include durian, bananas, cantaloupe, and tamarind.

Kidney-Friendly Diet for Chronic Kidney Disease (Stages 4–5)

At this stage, the kidneys are severely damaged or the patient is undergoing hemodialysis. The kidneys can no longer remove waste and excess fluid effectively, so most patients need dialysis to help clean the blood.

However, dialysis can also cause the body to lose important nutrients, especially protein, vitamins, and minerals. That’s why diet becomes extremely important and must be carefully managed.

1. Protein – Increase Intake Compared to Earlier Stages

At this stage, patients should consume about 1.0–1.2 g of protein per kg of body weight per day.For example, a person weighing 60 kg should aim for around 60–72 g of protein daily (calculation: daily protein in grams = body weight in kg × 1.0–1.2).

Focus on high-quality protein sources such as fish, lean meat, and 2–3 egg whites per day.

Avoid fatty meats, pork skin, duck skin, organ meats, and egg yolks.

📍 Eating too little protein can lead to weakness and a weakened immune system, but too much protein can cause waste to build up in the blood and not be fully removed by dialysis. Therefore, “just the right amount” is the key.

2. Fat – Choose Healthy Fats and Avoid Fried Foods

Patients on dialysis often have high blood fat levels. It’s important to limit saturated fats such as butter, cheese, and coconut milk, and instead use plant-based oils like olive oil or soybean oil.

Foods to avoid include:

• Egg yolks, fish eggs, squid, and oysters

• Animal organ meats

• Baked goods and fried foods, such as cakes, pies, and croissants

• Fast food, such as burgers and pizza

---

3. Energy – Eat Enough to Prevent Muscle Loss

Patients should consume about 30–35 kcal per kg of body weight per day.Around 60% of energy should come from carbohydrates and 30% from fat.

If energy intake is too low, body weight may decrease and muscle breakdown can occur quickly.

---

4. Minerals – Key Nutrients to Monitor

• Sodium: Limit to 1–2 g per day (about 1 teaspoon of salt or 2–5 teaspoons of fish sauce). Avoid pickled foods, processed foods, and salty snacks.

• Phosphorus: Found in beans, seeds, dairy, egg yolks, and chocolate. Take phosphate-binding medication with meals as prescribed by your doctor.

• Potassium: Control fruit intake and choose kidney-friendly options such as apples, rose apples, and grapes in moderate amounts.

---

5. Vitamins – Important Supplements for Kidney Patients

Dialysis can cause a loss of B and C vitamins. Take supplements as recommended by your doctor, but avoid vitamin A and high-dose vitamin C, as they can accumulate in the body.

---

6. Water – Drink the Right Amount

For patients in stages 4–5, drinking too little or too much water can be harmful.

When the kidneys are not working well, the body cannot remove excess fluid efficiently. Drinking too much water can lead to fluid overload, causing swelling, shortness of breath, or extra strain on the heart.

How Much Water Should You Drink?

Generally, doctors recommend drinking an amount about equal to your daily urine output, plus a little extra to keep your mouth comfortable (around half a small water bottle). You don’t need to measure every drop—just remember these simple rules:

• If you can still urinate: You can drink water, but avoid drinking large amounts at once.

• If urine output is very low or none: Limit fluids according to your doctor’s instructions.

💧 Remember, “water” includes all liquids—drinking water, soups, fruit juices, ice, or water-containing desserts like jelly and ice cream should all be counted.

Summary

Managing diet for chronic kidney disease patients should focus more on quality rather than quantity. Eat a balanced diet with all five food groups, choose easily digestible protein sources like fish or egg whites, and avoid very salty or pickled foods. Use healthy oils such as soybean or olive oil, and select low-potassium fruits like apples, rose apples, or grapes to help slow kidney deterioration.

Patients should regularly consult their doctor or dietitian to adjust their diet according to the stage of their kidney disease. In addition to diet, getting enough rest and maintaining a relaxed, stress-free mindset will help patients maintain both physical health and emotional well-being.
