For people with kidney disease, choosing healthy snacks can be challenging. Crackers are a popular snack food, but not all crackers are kidney-friendly. When you have chronic kidney disease (CKD), you need to follow a renal diet to limit potassium, phosphorus, and sodium. Choosing the right crackers is key to staying within your recommended limits.
Why limit potassium, phosphorus, and sodium with kidney disease?
Potassium, phosphorus, and sodium are minerals that can build up in your blood when your kidneys are not working well. This can lead to serious health problems:
- High potassium (hyperkalemia) can cause dangerous heart rhythm issues.
- High phosphorus (hyperphosphatemia) can cause bone disease and calcification of tissues.
- High sodium can increase fluid retention, raising blood pressure.
To prevent these complications, a renal diet limits certain foods that are high in these minerals. Unfortunately, many popular snack foods like chips, pretzels, and cheese crackers are very high in both phosphorus and sodium.
Choosing the best crackers for kidney health
When shopping for crackers, read nutrition labels carefully and look for these features:
- Low sodium: Choose crackers with less than 100-200mg sodium per serving.
- Low phosphorus: Aim for less than 50mg phosphorus per serving.
- Higher fiber: Look for at least 2-3g of fiber, which is filling and beneficial.
- Low potassium: Crackers are not usually very high in potassium, but check the label.
Some good cracker options for a renal diet include:
Ryvita Crispbread
- 80mg sodium
- 30mg phosphorus
- 6g fiber
Blue Diamond Nut Thins
- 105mg sodium
- 20mg phosphorus

Kashi Original 7 Grain Crackers

Cracker ingredients to limit on a renal diet
When shopping for crackers, avoid these ingredients which are high in phosphorus and sodium:
- Bleached flour
- Buttermilk
- Cheese
- Baking powder
- Monosodium glutamate (MSG)
Tips for enjoying crackers on a renal diet
Here are some tips to help you incorporate crackers into your kidney-friendly eating plan:
- Stick to 1-2 servings of crackers per day to limit sodium.
- Look for unsalted crackers and add your own spices for flavor.
- Pair crackers with kidney-friendly foods like hummus, peanut butter, or avocado.
- Avoid crumbling crackers into soups or salads, as this adds phosphorus.
- Be mindful of portion sizes and don’t overindulge.
