Kidney Stone-Friendly Sides and Snacks

Small Changes, Big Impact

Even small changes in the way you snack can help you reduce how much sodium, oxalate and uric acid you eat. Sides and snacks are often overlooked, but they can be hidden sources of stone-promoting ingredients. Here are lots of tips and recipes to help spark your own ideas to fight kidney stones with healthy sides.

Smart Swaps for Sides and Snacks

Change the chips. Bring homemade kale chips instead of potato chips to your next picnic.
Wise fries. Replace your beloved french-fried potatoes with carrot sticks.
Switch sauces. Substitute mashed avocado for mayo on a sandwich - it provides mono-unsaturated fats and a good dose of green! Greek yogurt is another favorite substitute for mayo.
Don't boot the fruit. Wonderful fresh fruit is very low in oxalates and salts. Keep melon or grapes on hand for a snack.

Snacks to Avoid

High-Risk Snack Foods

Try to avoid these salty, high-oxalate, or high-purine snacks:

Pickles and marinated vegetables
Olives
Cured meats
Bacon and bacon bits
Seasoned croutons
Hard cheeses
Salted seeds and nuts
Potato chips and french fries
Commercial snack mixes

Remember: Although these things are small, they can be very salty and contribute significantly to your daily sodium and oxalate totals.
