Best for

• Older adults with mild kidney concerns or early chronic kidney disease (CKD 1–3) looking to reduce salt and improve hydration.
• People who feel puffy, get leg swelling, or notice higher blood pressure when eating restaurant/packaged food.
• Caregivers who need a simple, repeatable 1-week structure.

Avoid or get medical guidance first

• CKD stage 4–5, on dialysis, or rapidly changing kidney numbers.
• Recent illness, vomiting/diarrhea, or dehydration.
• Taking meds that affect potassium/fluid (e.g., spironolactone) without a clinician’s plan.
• Low-sodium restrictions and heart failure — discuss fluid limits with your clinician first.

This is educational, not medical advice. Personalize with your healthcare team.

• Sodium: aim ~1,500–2,000 mg/day (unless your clinician sets different).
• Fluids: sip through the day to meet your personalized target (often 1.5–2 L/day if no restriction).
• Protein: steady, moderate: ~0.8 g per kg body weight unless told otherwise.
• Fiber: add plants and whole grains to keep bowels regular and support blood sugar.
• Movement: 10–20 minutes gentle walking or chair exercises daily (as safe).

Produce

• Apples, berries, grapes (kidney-friendly fruits)
• Cucumber, carrots, bell peppers, green beans, cabbage
• Leafy greens (small portions if potassium-restricted)
• Lemon/lime for flavor

Proteins

• Skinless chicken, white fish (tilapia/cod), eggs or egg whites
• Unsalted peanut butter, tofu (check sodium)
• Plain Greek yogurt (check phosphorus additives)

Grains & pantry

• Old-fashioned oats, rice, whole-wheat or low-sodium bread/wraps
• Dry lentils/split peas (portion mindful if potassium-restricted)
• Unsalted nuts/seeds (small handfuls)
• Low-sodium broth, no-salt spice blends (garlic powder, pepper, herbs)
• Olive oil, vinegar (apple cider/rice), mustard (check sodium)

Beverages

• Water, lemon water, unsweet tea, coffee (limit sugary drinks)

Fluids (general idea)

• Common target is 1.5–2 L/day unless you have a fluid restriction. Spread sips through the day.
• Use a marked bottle (500 mL) and aim for 3–4 fills.
• Limit sugary drinks; avoid “sports” drinks unless instructed.

Sodium

• Goal: 1,500–2,000 mg/day. Main sources are packaged food, restaurant meals, deli meats, canned soups, pickles.
• Swap with herbs, garlic, onion powder, citrus, vinegar, pepper, smoked paprika.
• Choose “no salt added” or products with ≤140 mg per serving.

Potassium

• Some with CKD must limit high-potassium foods (bananas, oranges, potatoes, tomatoes, spinach, beans). Your lab (“K+”) guides this.
• Lower-potassium options: apples, berries, grapes, cabbage, green beans, rice, oats, lettuce, peppers.
• Cooking trick: “leach” potatoes (peel, cube, boil in fresh water, drain) to reduce potassium.

Phosphorus

• Prefer fresh foods. Additives like “phosphate,” “phosphoric acid,” “pyrophosphate” in processed meats/cheeses/sodas raise phosphorus quickly.
• Choose dairy in modest portions; check if you need a binder (clinician-directed).
• Dark colas & processed cheese often contain phosphate additives — limit or pick alternatives.

Morning (2–3 minutes)

• Weigh yourself after bathroom. Gain >2 lb (1 kg) in 24–48 hr? Note it.
• Check blood pressure if you have a cuff. Record.
• Fill your water bottle for the day; schedule short walk.

Evening

• How were swelling, breath, energy?
• Did you keep salt lower and take meds on time?
• Plan breakfast + one protein for tomorrow.

Will I see changes in a week?

Many people notice less ankle swelling, fewer nighttime bathroom trips, and steadier blood pressure within days. Lab changes (creatinine, potassium) are monitored by your clinician over time.

How much protein is “moderate”?

A common target is ~0.8 g/kg/day (for 70 kg ≈ 56 g/day), adjusted for diabetes, frailty, or dialysis. Spread protein through meals.

Do I need special “renal” products?

Not usually. Focus on fresh foods, low-sodium choices, and avoiding phosphate additives. Use specialty products only if advised.

What about potassium restrictions?

Only if your labs or clinician say so. If restricted, swap to lower-potassium fruits/veggies and use leaching for potatoes. Recheck labs as scheduled.
