Eating Well With Kidney Disease on a Limited Budget

Sodium

Sodium affects blood pressure and fluid balance, which are important for kidney health. With kidney disease, too much sodium can make it harder for your kidneys to do their job and may lead to swelling or shortness of breath. Lowering sodium does not have to mean expensive foods. Simple choices, like rinsing canned foods and using herbs and spices, can help you manage sodium on a budget.

Lower sodium helps protect your kidneys and blood pressure.

• Limit processed foods when possible
• Rinse canned vegetables and beans
• Choose frozen vegetables without sauces
• Use herbs and spices for flavor

Potassium

Potassium helps your muscles and heart work properly, but kidney disease can make it harder to keep potassium in a safe range. Some lower cost foods are higher in potassium, so knowing what to look for can help you make safer choices. Paying attention to labels and choosing fresh or frozen foods when possible, can help you manage potassium while staying within your budget.

• Choose fresh or frozen vegetables
• Compare canned foods and avoid potassium preservatives
• Rinse canned beans and vegetables

Phosphorus

Phosphorus builds up in the body more easily when kidneys are not working well. High phosphorus levels can weaken bones and affect heart health over time. Many low costs processed foods contain phosphorus additives, which are harder for your body to handle. Choosing simple, less processed foods can help limit phosphorus without increasing food costs.

• Choose simple foods like eggs and unprocessed meats
• Limit deli meats, processed cheese, and dark colas
• Check ingredient lists for “phos” additives

Drinks can add extra sodium, potassium, or phosphorus without you realizing it. Sugary drinks and dark sodas can also affect overall health. Water is usually the best and most affordable choice. Making small changes to what you drink can help protect your kidneys and reduce unnecessary costs.

Water helps your kidneys remove waste and keep your body in balance. For some people with kidney disease, fluid needs may change, and your doctor or dietitian can help guide how much is right for you. Access to clean, safe drinking water is important for kidney health, but not everyone has reliable access.

If clean water is limited, options like bottled water, community water stations, or boiling tap water may help. A social worker or local community program can also help identify safe water resources in your area. If you are unsure about the safety of your water, talk with your care team so they can help you find solutions that work for you.

Planning ahead can make it easier to stretch food, reduce waste, and simplify meals. Even small planning steps can help you make the most of the foods you have while supporting kidney health.

• Plan meals before shopping
• Make a grocery list and stick to it
• Cook in batches and freeze leftovers
• Buy grains and beans in bulk
• Choose seasonal produce
• Store foods properly to reduce waste

Supporting your kidneys does not require big changes all at once. Starting with small, realistic steps can help you build habits that fit your life and resources

• Choose two low-cost protein foods to keep on hand
• Add one frozen vegetable to weekly meals
• Plan two meals using foods you already have
• Compare labels for sodium and potassium
• Check one local food support resource

Your dietitian or social worker can help you find food options and resources that fit both your kidney needs and your budget. Asking these questions can be helpful if food costs, access, or meal planning feel challenging, or if you are having trouble following nutrition recommendations.

• What foods fit my budget and kidney needs?
• How much protein should I eat each day?
• Which canned or frozen foods are okay for me?
• What foods or drinks should I limit most?
• What should I do if I cannot afford everything recommended?
• Can you help me find local food support programs?
