What To Eat With Chronic Kidney Disease: A Kidney Diet Plan

If you have chronic kidney disease (CKD), the best diet is usually built around moderate protein, low sodium, fresh (not processed) foods, and controlled potassium and phosphorus based on your blood tests.

International kidney guidelines (KDIGO 2024) recommend about 0.8 grams of protein per kilogram of body weight per day for adults with CKD stages 3 to 5 who aren’t on dialysis, and less than 2 grams of sodium a day (about 5 grams of salt).

One of the most useful tips: avoid packaged and processed foods with phosphate additives, since phosphorus from additives is absorbed at 90% to 100%, compared with about 30% from plant foods.

There’s no single “kidney diet” for everyone, because needs change with your CKD stage, lab results, diabetes, and dialysis status.

This article covers kidney-friendly foods, foods to limit, fruits and vegetables, bananas, Indian diet tips, a sample diet chart, and whether any foods can “repair” kidneys.

What Is A Kidney Diet (Renal Diet)?

A renal diet helps reduce strain on your kidneys and prevent dangerous buildup of minerals and waste. It usually focuses on five things:

Nutrient	Why It Matters In CKD
Sodium	Raises blood pressure and causes swelling
Protein	Too much may strain kidneys; too little causes muscle loss
Potassium	Can build up and cause dangerous heart rhythms
Phosphorus	Builds up and weakens bones and blood vessels
Fluids	May need limits in advanced CKD or dialysis

How Much Protein Should You Eat With CKD?

The KDIGO 2024 guideline recommends 0.8 g of protein per kg of body weight per day for adults with CKD stages 3 to 5, which matches the general population’s recommended intake.

It also advises not to exceed 1.3 g/kg/day in people at risk of progression.

Your Weight	Daily Protein At 0.8 g/kg
50 kg	About 40 g
60 kg	About 48 g
70 kg	About 56 g
80 kg	About 64 g

Important exceptions:

Situation	Protein Guidance
On dialysis	Usually needs more protein
Malnourished or losing muscle	Avoid low protein
Children with CKD	Protein shouldn’t be restricted
Very low-protein diets	Only under specialist supervision

Some guidelines (like KDOQI 2020) suggest lower protein for some people, so your nephrologist or dietitian should set your target.

How Much Sodium Should You Eat?

KDIGO recommends limiting sodium to less than 2 g per day for people with CKD.

Salt Source	Tip
Table salt	Use herbs, lemon, garlic, and spices instead
Pickles and papads	Very high in salt; limit or avoid
Packaged snacks (namkeen, chips)	Very high in salt
Restaurant and street food	Often very salty
Sauces and instant noodles	High in sodium

Warning: avoid “low-sodium” salt substitutes made with potassium chloride unless your doctor approves. They can raise potassium to dangerous levels.

Phosphorus: Why Processed Foods Are The Biggest Problem?

A review found phosphorus from processed foods and additives is absorbed at 90% to 100%, compared with 40% to 80% from animal foods and about 30% from plant foods.

The authors concluded that additives in processed foods promote high phosphorus and may speed CKD progression.

High-Phosphorus Foods To Limit	Why
Colas and dark sodas	Contain phosphoric acid
Processed meats (sausages, ham)	Phosphate additives
Processed cheese and cheese spreads	Phosphate additives
Packaged baked goods and mixes	Additives
Fast food	Additives and salt

Label tip: look for ingredients containing “PHOS” (like sodium phosphate or phosphoric acid) and avoid them when possible.

Potassium: Do You Need To Limit It?

Not everyone with CKD needs to limit potassium. It depends on your blood potassium level.

If your doctor says your potassium is high, these tips help:

High-Potassium Foods	Lower-Potassium Choices
Bananas	Apples
Oranges and orange juice	Berries
Potatoes and sweet potatoes	Rice, pasta, white bread
Tomatoes and tomato sauce	Cabbage, cauliflower
Spinach (cooked)	Cucumber, lettuce
Coconut water	Plain water
Dried fruits	Grapes, pineapple
Avocado	Bell peppers (capsicum)

How To Reduce Potassium In Vegetables?

Cooking method matters. US Department of Agriculture researchers found that cubing or shredding potatoes before boiling them can reduce mineral content, including potassium, by as much as 75%.

Surprisingly, soaking potatoes overnight without boiling had no significant effect on potassium.

Method	Effectiveness
Cut into small pieces, then boil and drain	Most effective
Boil, discard water, boil again	Very effective for tubers
Soak only (no boiling)	Little effect

For yams and similar root vegetables, a study found that boiling, rinsing, and boiling again brought some below 200 mg of potassium per 100 grams, while soaking alone didn’t remove enough. Note that boiling also removes water-soluble vitamins like vitamin C and B vitamins.

What Are The Best Foods For Kidney Health?

Here are 10 kidney-friendly foods for many people with CKD (adjust based on your labs):

#	Food	Why It’s Kidney-Friendly
1	Cabbage	Low potassium, rich in vitamins and fiber
2	Cauliflower	Low potassium, versatile
3	Apples	Low potassium, high fiber
4	Berries	Antioxidants, lower potassium
5	Bell peppers (capsicum)	Low potassium, vitamin C
6	Onions and garlic	Add flavor without salt
7	Egg whites	High-quality protein, low phosphorus
8	Olive oil	Healthy fat, no potassium or phosphorus
9	Rice and refined flour roti (in moderation)	Lower potassium and phosphorus than whole grains
10	Fish (moderate portions)	High-quality protein, healthy fats

Note: whole grains and legumes are healthy but higher in phosphorus and potassium. Plant phosphorus is less absorbed, so many dietitians now allow them in moderation, depending on your labs.

What Fruit Is Good For Kidneys?

What fruit is good for kidneys? For people who need to limit potassium:

Lower-Potassium Fruits	Higher-Potassium Fruits
Apples	Bananas
Pears	Oranges
Berries (strawberries, blueberries)	Mangoes (large portions)
Grapes	Melons (large portions)
Pineapple	Dried fruits
Papaya (small portions)	Guava, kiwi

Important warning: people with kidney disease should avoid star fruit (kamrakh). It contains a toxin that kidneys can’t clear, which can cause serious neurological problems.

Are Bananas Good Or Bad For Kidneys?

Bananas are healthy for most people, but they’re high in potassium (a medium banana has roughly 400 mg).

If your potassium is normal, you may not need to avoid them. If your potassium is high, your dietitian may advise limiting or avoiding bananas.

Situation	Bananas
Early CKD with normal potassium	Usually fine in moderation
CKD with high potassium	Limit or avoid
On dialysis	Usually limited

What Vegetables Are Good For Kidney Disease?

Lower-Potassium Vegetables	Higher-Potassium Vegetables
Cabbage	Potatoes
Cauliflower	Tomatoes
Bottle gourd (lauki)	Spinach (palak)
Ridge gourd (turai)	Sweet potatoes
Cucumber	Pumpkin (large portions)
Capsicum	Drumstick leaves
Onion	Mushrooms
Green beans	Beets

Foods To Avoid With Kidney Disease

Foods bad for kidneys in CKD usually include:

Food	Problem
Pickles, papads, namkeen	Very high sodium
Processed and packaged foods	Sodium and phosphate additives
Colas	Phosphoric acid
Processed meats	Sodium and phosphates
Star fruit	Toxic in CKD
Potassium-based salt substitutes	Dangerous potassium spike
Excess protein supplements	May strain kidneys
Unapproved herbal supplements	Some damage kidneys
Coconut water (if potassium is high)	High potassium
Excess alcohol	Raises blood pressure

Renal Diabetic Diet: CKD With Diabetes

A renal diabetic diet combines kidney and blood sugar goals:

Goal	How
Control blood sugar	Limit sugar and refined carbs; spread carbs through the day
Moderate protein	About 0.8 g/kg/day (per KDIGO)
Low sodium	Under 2 g/day
Manage potassium and phosphorus	Based on labs
Choose low-potassium fruits	Apples, berries, pears

Your dietitian can help balance these goals, which sometimes conflict (for example, whole grains help blood sugar but are higher in phosphorus).

Indian Diet Chart For Kidney Patients (Sample)

This is a general example for CKD stage 3 without dialysis. Portions, potassium, and phosphorus must be adjusted for your labs.

Time	Sample Meal
Early morning	Plain water or tea with less milk, no sugar if diabetic
Breakfast	Poha or upma with vegetables (low salt), or 2 egg whites with toast
Mid-morning	1 apple or a small bowl of papaya
Lunch	2 small rotis or rice, lauki or cabbage sabzi (low salt), small bowl of dal (well-cooked), cucumber salad
Evening	Puffed rice (murmura) without salt or a few unsalted crackers
Dinner	Rice or roti, cauliflower or turai sabzi, small portion of fish, chicken, or paneer (as advised)
Bedtime	Small cup of milk only if phosphorus allows

Tips for Indian kitchens:

Tip	Why
Cook vegetables in extra water and drain	Reduces potassium
Use lemon, jeera, coriander, ginger, garlic	Flavor without salt
Limit dal portions if potassium or phosphorus is high	Dal is rich in both
Avoid achar, papad, and namkeen	Very high in salt
Limit curd and paneer if phosphorus is high	Dairy is high in phosphorus

People searching for a kidney patient diet chart in Hindi or a CKD diet chart PDF should ask their hospital’s renal dietitian, who can provide a chart in Hindi tailored to their lab results.

Stage 3 Kidney Disease Diet

For a stage 3 kidney disease diet:

Focus	Recommendation
Protein	About 0.8 g/kg/day
Sodium	Under 2 g/day
Potassium	Limit only if blood levels are high
Phosphorus	Avoid additives; limit dairy if levels are high
Fluids	Usually not restricted unless advised
Overall pattern	Fresh, minimally processed foods

If you find it hard to stick to these changes every day, a guided kidney disease solution plan can help you build consistent habits alongside your dietitian’s advice.

What Foods Help Repair Kidneys?

What foods help repair kidneys? No food can repair or regrow damaged kidney tissue, which is why many people ask if CKD is curable at all. But a kidney-friendly diet helps:

Diet Benefit	How
Slower CKD progression	Lower blood pressure and protein load
Fewer complications	Controlled potassium and phosphorus
Better blood sugar control	Protects kidneys in diabetes
Less swelling	Lower sodium
Healthier heart	Reduced cardiovascular risk

What Foods Increase GFR?

What foods increase GFR? No food has been proven to raise GFR in a lasting, healthy way. Very high protein intake can temporarily raise GFR, but this “hyperfiltration” may strain the kidneys.

Be cautious of products claiming to “boost kidney function.” If you’re wondering, “how can I improve my kidney function?”, our article covers proven, evidence-based steps.

Chia Seeds And Kidney Stones

Chia seeds and kidney stones is a common question. Chia seeds are high in fiber, but they’re also rich in phosphorus and potassium, which matters in CKD.

Evidence directly linking chia seeds to kidney stones is limited. If you have CKD or a history of oxalate stones, ask your dietitian before adding large amounts of seeds or nuts.

So, What Foods Should You Eat If You Have Chronic Kidney Disease?

A kidney-friendly diet focuses on fresh, minimally processed foods, moderate protein (about 0.8 g/kg/day for CKD stages 3 to 5 not on dialysis), and low sodium (under 2 g/day).

Avoid processed foods with phosphate additives, which are absorbed much more easily than natural phosphorus.

Limit potassium only if your blood levels are high, and use cooking methods like cutting and boiling to reduce potassium in vegetables.

Good choices for many people include cabbage, cauliflower, lauki, apples, berries, egg whites, fish in moderation, and olive oil.

Avoid star fruit, salt substitutes with potassium, pickles, papads, colas, and unapproved herbal supplements.

Most importantly, work with a renal dietitian, since the right diet depends on your stage, lab results, diabetes, and dialysis status. If you also want a structured lifestyle article, read our full review of the CKD Solution program.
