Diet Guide · For non-dialysis CKD
Three tiers of safety, six smart swaps, and one sample day to make tomorrow easier. Click any food to see its full nutrient breakdown.

Marketed as healthy salt, but the potassium replacing sodium causes blood-K spikes a damaged kidney can't clear.
Try instead: Use a small amount of regular salt while cooking, then build flavour with lemon juice, black pepper, cumin, and coriander.
The phosphoric acid in colas is additive phosphorus — your body absorbs nearly all of it. Diet sodas with phosphate count too.
Try instead: Chilled herbal tea, sparkling water with lime, or buttermilk diluted with water if fluids allow.
Triple-loaded — high sodium, hidden additive phosphorus (PHOS in the ingredient list), and animal protein in a heavy serving.
Try instead: A small portion (1 oz) of fresh chicken breast, tofu, or tempeh — your dietitian will tell you the right size for your stage.
Five-minute cheat sheet
Most "lite salt" / sendha namak / lo-salt blends contain potassium chloride — straight hyperkalemia risk.
Additive phosphorus is absorbed almost 100%. The natural kind in dal and dairy is much less aggressive.
Cook with a little; never add at the plate. Choose packaged foods at ≤ 200 mg sodium per serving.
It lowers acid load, slows progression, and your body absorbs less phosphorus than from meat or dairy.
Skip frozen dinners, canned soups, deli meats — they hide both sodium and additive phosphorus.

Potassium
Potassium keeps the heart firing. Damaged kidneys can't clear excess — and a spike is dangerous fast. Build mostly from the green list, ration the amber, and treat red items as occasional.
How the 113 potassium-listed foods break down
Build most of your plate from this list.
Less than 150 mg per serving
Dietitian's nudge: Aim to fill 2/3 of your plate from this list at every meal.
One serving a day, with your dietitian's nod.
150 – 250 mg per serving
Dietitian's nudge: Treat these as half-cup portions and don't double up across meals.
A small taste, not a regular slot.
More than 250 mg per serving
Dietitian's nudge: If you really want one of these, ask your dietitian about leaching or smaller portions.
Phosphorus
High blood phosphorus pulls calcium out of bones and stresses the heart. The natural kind (dal, dairy) is absorbed at ~50%. The additive kind (PHOS in ingredient lists, dark cola) is absorbed almost entirely — that's the dangerous one.
Eat freely · staple territory.
Dietitian's nudge: Reach for these for your everyday grains and dairy substitutes.
Limit · portion-aware.
Dietitian's nudge: If labs run high, your dietitian may recommend a phosphate binder with these.
Smart swaps
Six familiar substitutions. Same role on the plate, far less potassium or phosphorus.
Apple is in the low-K tier; banana is high-K. Same sweet snack, gentler on labs.
Cabbage sabzi has under 150 mg K per serving vs spinach's 600+ — and it cooks the same way.
Orange juice
Apple juice
Apple juice falls in the low-K tier; orange juice is high-K.
Cow milk
Plain almond milk
Almond milk is lower in both phosphorus and potassium. Check the label — pick unsweetened, unenriched.
Cauliflower mash is the classic low-K stand-in for mashed potato. Same comfort, far less potassium.
Tomato gravy
Bottle gourd (lauki)
Lauki sabzi keeps the curry-with-rice rhythm with a fraction of the potassium of tomato-based gravies.
A safe day on a plate
Breakfast
Poha with peanuts, lemon, and curry leaves · one apple
Rice flakes are low in potassium; lemon brightens flavour without adding salt.
Lunch
Two chapatis · cabbage sabzi · small katori moong dal · cucumber raita
Cabbage and cucumber keep potassium low; moong dal portion is deliberately small.
Dinner
Steamed rice · lauki curry · grilled chicken breast (one ounce)
Bottle gourd is the lowest-K vegetable on the list; the meat portion is one ounce for a reason.
Snacks
Unsalted popcorn · few melon slices · plain tea (½ cup)
If you're on a fluid restriction, count the tea against the day's allowance.
Protein
Choose more plant-based protein. It decreases acid load, slows kidney-disease progression, helps muscle preservation, and lowers phosphorus absorption (plant phosphorus is less bioavailable).
*Plant sources marked with an asterisk may be high in potassium — ask your dietitian how to fit them into your plan.
Sodium
With CKD, sodium is harder to clear — extra means fluid retention, higher blood pressure, and more strain on kidneys and heart. Salt substitutes are not a safe escape: most contain potassium chloride.
Do not add salt at the table — only a little in cooking.
Read labels and choose foods with ≤ 200 mg sodium per serving (140 mg is considered low sodium).
Watch out for salt blends — many "salt substitutes" contain potassium and trigger hyperkalemia.
Soy sauce and other Asian sauces are usually high in sodium.
Avoid convenience and packaged foods (frozen dinners, canned soups, deli meals).
Avoid fast food (commercial burgers, pizzas, tacos) and cured / processed meats and cheeses.
Avoid salted snack foods.
Avoid vegetables canned or processed with salt — choose fresh or frozen.
Fluids
If your doctor has restricted fluids, count everything liquid at room temperature — not just water. Kulfi, sherbet, masala chai all count too.
