Dining out can be tricky for people with chronic kidney disease (CKD) or those concerned about kidney health. But with a few smart choices and strategies, it’s absolutely possible to enjoy meals outside without compromising your kidney function. This post shares practical tips, examples, and dining strategies to help you eat out safely.
1. Why Dining Out Can Be Risky for Your Kidneys
For CKD patients, it’s important to control intake of sodium, potassium, phosphorus, and protein. Unfortunately, restaurant meals often contain excessive salt, sauces, and hidden additives, making it hard to track nutrient content.
Examples:
-
A typical Korean soybean paste stew (doenjang-jjigae) can contain over 1,500–2,000 mg of sodium.
-
A serving of fried pork cutlet (donkatsu) contains excessive protein and fat.
-
Buffet-style hotpots or meat dishes may be high in phosphorus and potassium.
2. Six Essential Rules for Kidney-Friendly Dining Out
① Avoid Soup Broths
Broths are packed with sodium. Stick to solid ingredients and avoid drinking the soup whenever possible.
📌 Example: If ordering ox bone soup (seolleongtang), eat only the meat and rice, leave the broth.
② Choose Grilled or Steamed Dishes
Avoid fried foods. Opt for grilled or steamed dishes with minimal seasoning.
📌 Example: Choose grilled pork belly without sauces, eat it with lettuce wraps and rice.
③ Limit Side Dishes
Avoid salted side dishes like kimchi, pickles, and fermented seafood. Choose 2–3 mild vegetable side dishes.
📌 Example: From 10 banchan (side dishes), pick just 2 vegetable-based ones.
④ Choose Water or Unsweetened Tea
Avoid broth-based drinks or sugary sodas. Go with barley tea or plain water.
📌 Example: Request warm barley tea instead of soup or soda.
⑤ Skip Sauces and Dressings
Condiments like soy sauce, ketchup, and mayonnaise are full of sodium and phosphorus. Request them on the side or skip entirely.
📌 Salad? Ask for it without dressing, or with lemon juice instead.
⑥ Communicate with the Restaurant
Ask politely: “Can you make it less salty?” or “Please serve sauces separately.” Many restaurants are happy to accommodate.

Mr. A (58 years old, Stage 3 CKD) used to struggle with frequent business dinners and family outings. By making smarter choices, his kidney function and blood pressure stabilized.

5. Pro Tips Before and After Dining Out
✅ Eat a Small Snack Beforehand
To avoid overeating: 5–10 nuts, a few apple slices, or half a sweet potato can help control hunger.
✅ Check Nutritional Info
Chain restaurants often provide nutrient data—look for sodium, protein, and potassium values.
✅ Take a Post-Meal Walk
To help lower blood pressure and glucose spikes, walk for 20–30 minutes after eating.
6. Build Your Own Rules for Dining Out
Instead of avoiding dining out altogether, set your own rules:
✔️ “No broth”
✔️ “Pick 2 veggie sides”
✔️ “No dressing on salad”
Once these become habits, eating out becomes less stressful and more enjoyable.
