Thriving with Proteinuria: Nurturing Kidney Health through Lifestyle and Diet
Just because you’re living with proteinuria doesn’t mean that you still can’t live a healthy, vibrant, and fulfilling life. Making lifestyle modifications and dietary adjustments can go a long way in supporting your kidney health, and we think you’ll be surprised to learn that most of the tips we’re going to share in this post are rather practical. These tips and insights—courtesy of Florida Kidney Physicians (FKP)—will help you better navigate the nuances of proteinuria. In turn, you’ll feel more in control of your health and the direction in which it’s heading.
Understanding Life with Proteinuria
Being diagnosed with proteinuria may be disconcerting, but you can take this diagnosis for what it is: a sign that your kidneys are struggling, and a call to action to help them in any way you can. Living with proteinuria requires a thoughtful approach to daily life. If you’re ready to make proactive lifestyle choices that can significantly contribute to overall health and the well-being of your kidneys, your care team and the support network you build can assist you in incorporating them. Do whatever you can to increase the chances of maintaining these changes in the long run so you can ensure a sustained impact on your kidney health. Consistency is key!
Kidney-Friendly Diet Tips
A healthy, well-balanced diet is essential for staying healthy; it supplies your body with all the nutrients it needs so you can function at your best. A well-balanced diet is the type of diet that everyone should follow—especially proteinuria patients. Here are some kidney-friendly diet tips that you can start implementing as soon as today!
- Balanced Nutrition
Make sure that you’re eating plenty of fruits, vegetables, whole grains, and lean proteins. A proteinuria diet will supply your body with essential nutrients without overloading your kidneys. If you need help creating a balanced diet, talk to your doctor or schedule an appointment with a registered dietician. It’s important to ensure that you’re fueling your body with an adequate amount of calories, including calories derived from healthy fats and carbohydrates. Establishing a balanced proteinuria diet might be challenging, especially if you have an underlying condition like diabetes or heart disease, so seeking guidance from an expert is a good idea. An effective proteinuria diet will also involve careful meal planning so you can make it easier to stay on track and resist temptations that could derail your efforts.
- Limiting Sodium Intake
As much as you might want to reach for the saltshaker when cooking or while eating out, try your best to limit your sodium intake. Sodium can lead to fluid retention, which can raise your blood pressure and put extra strain on your kidneys. According to American Kidney Fund (AKF), “The amount of sodium found naturally in foods is enough to keep a healthy level in your body. One of the best things you can do is to limit how much sodium you eat. A general rule is to have less than 2,300 milligrams of sodium each day.” We encourage you to check food labels, limit your intake of processed and packaged foods, and eat as many fresh foods as possible.
- Protein Moderation
Protein is an essential part of a healthy diet; it builds and repairs muscles, and even helps you fight infections. However, proteinuria patients need to consume protein in moderation. Your healthcare provider may recommend adjusting your protein intake based on your nutritional needs and the severity of your proteinuria. An article published by Cleveland Clinic notes the value of avoiding a high-protein diet: “As we age, it’s normal for our kidneys to experience wear and tear. The added stress of a high-protein diet can contribute to kidneys losing their protein-processing powers. It becomes harder for them to keep the protein for your body to use, so more and more comes out in your urine.”
- Watching Phosphorus and Potassium
Monitoring phosphorus and potassium intake is crucial for individuals with proteinuria and kidney issues because these minerals can influence how your kidneys function. High levels of phosphorus and potassium can be detrimental to kidney health because they force your kidneys to work harder to filter and excrete these minerals. Foods high in phosphorus include dairy foods, beans, nuts, lentils, and oatmeal, just to name a few.
Potassium-rich foods include bananas, avocados, spinach, kale, tomatoes, cucumbers, zucchini, milk, yogurt, and many more. We recommend choosing foods that are lower in these minerals so you can successfully manage proteinuria and minimize the risk of proteinuria complications.
- Limiting Phosphorus-Rich Foods
Mayo Clinic writes, “Phosphorus is a mineral that’s found naturally in many foods and also added to many processed foods. When you eat foods that have phosphorus in them, most of the phosphorus goes into your blood. Healthy kidneys remove extra phosphorus from the blood. If your kidneys don’t work well, you can develop a high phosphorus level in your blood, putting you at greater risk of heart disease, weak bones, joint pain and even death.” Even though phosphorus is a mineral that your body needs, high phosphorus levels can do more harm than good for your kidneys. We want to stress how phosphorous can impair kidney function, making it more difficult for your kidneys to filter and remove metabolic waste. Lowering your phosphorous intake can prevent kidney damage. Check food labels to determine if any ingredients contain “phos” in the term—examples include “calcium phosphate” and “phosphoric acid.” Please refer to the helpful table that Mayo Clinic has published—it lists foods high in phosphorous and then suggests low phosphorus alternatives. Remember, even small adjustments can make a big difference.
Hydration and Fluid Intake
Even though your kidneys filter blood, remove excess fluids, and eliminate metabolic waste, don’t just think of your kidneys as filters—when it comes to hydration and fluid intake, think of them as sponges, too! Your kidneys thrive on consistent fluid intake, so here’s why you should pay attention to hydration and fluid intake.
- Staying Hydrated
We can’t overstate the importance of drinking water from the moment you wake up in the morning until the time you go to bed at night. Staying well-hydrated not only supports overall kidney function but also helps your body flush out harmful toxins. If you’re prone to kidney stones, you’ll appreciate that proper hydration can help break up minerals in your kidneys that can crystallize over time and form kidney stones. Carry a water bottle with you every day to ensure that you’re replenishing lost fluids, especially if you live in a hot climate or have just finished exercising. By the way, water is the most ideal beverage you can drink—it’s refreshing, thirst-quenching, and free of calories.
- Balancing Fluid Intake
Even though hydration is crucial, we want to make you aware that excessive fluid intake may strain your kidneys. There is such a thing as “overhydration.” Consuming too much fluid can disrupt the delicate electrolyte balance in your body and force your kidneys to work harder than they already do. Maintaining a fluid intake balance can be accomplished by establishing fluid goals that are based on recommendations from your trusted healthcare provider. They’ll take several factors into account (existing conditions, medications, and activity levels, for example) so there’s no guesswork in how much water you should aim to drink each day.
- Limiting Caffeine and Alcohol
Do you make yourself a cup of coffee each morning? How about wine—do you reach for a glass during dinner each night? As enjoyable as these beverages may be, excessive caffeine and alcohol consumption can contribute to dehydration. We advise you to limit your intake of both caffeine and alcohol so you can stay adequately hydrated and help your kidneys function at optimal levels. Your doctor or dietician can discuss alternative beverage options—perhaps, for instance, you’d be willing to swap alcoholic for non-alcoholic beverages, or decrease the number of cups of coffee you drink. Making compromises can help you meet your hydration and health goals so you don’t have to feel discouraged about sacrificing beverages that you enjoy consuming.
Physical Activity and Exercise
Perhaps the Centers for Disease Control and Prevention (CDC) website says it best: “Regular physical activity is one of the most important things you can do for your health. Being physically active can improve your brain health, help manage weight, reduce the risk of disease, strengthen bones and muscles, and improve your ability to do everyday activities. Only a few lifestyle choices have as large an impact on your health as physical activity. Everyone can experience the health benefits of physical activity – age, abilities, ethnicity, shape, or size do not matter.”
If you have proteinuria, make a point to establish a consistent exercise routine. Regular physical activity can improve your kidney function and your overall health. Find an exercise that you enjoy doing and one that aligns with your fitness level. Bicycling and swimming are low-impact exercises that provide an effective workout while being gentle on your joints. Perhaps you’d enjoy hiking with your dog, walking around the block with a friend or neighbor, or even going to the gym to lift weights or join a Pilates class. If you can make your exercise routine something that you look forward to daily, you’ll be more inclined to keep exercise part of your lifestyle. Harvard Health recommends charting your progress, setting achievable goals, and rewarding your efforts so you can reap all the physical and mental benefits that exercise affords.
Stress Management
MedlinePlus defines stress as “how your brain and body respond to a challenge or demand. When you are stressed, your body releases certain hormones. The hormones that are released when you are stressed make you alert and ready to act. They can raise your blood pressure, heart rate, and blood glucose (blood sugar) levels. This response is sometimes called a ‘fight or flight’ response.” Even though it’s normal to experience stress at home, work, and/or school, prolonged stress can have a negative impact on your health, including your kidney health. Chronic stress may impact kidney function; NKF’s article titled “Stress and Your Kidneys” mentions that “as the blood filtering units of your body, your kidneys are prone to problems with blood circulation and blood vessels.” Stress and uncontrolled reactions to stress can lead to kidney damage because these organs are so closely associated with your heart and your body’s blood vessels.
Managing stress can prevent further kidney damage, especially among patients with proteinuria. There are many stress management techniques that you can employ—you just have to find the ones that work best for you. Maybe you feel calm when you retreat into a quiet room with a book, go for a jog, snuggle up with a pet, or call a friend or family member. Some people also enroll in talk therapy; regular counseling sessions permit you to vent your frustrations and generate useful coping strategies. Mindfulness, meditation, and relaxing hobbies are also options; unwinding during times of stress can make it easier for you to approach the problem you’re experiencing with greater ease and mental clarity. If you aren’t sure which stress management techniques would work best for you, take an open-minded approach next time you feel stressed so you can refine your approach and uncover the stress management techniques that resonate most.
Collaboration with Healthcare Providers
Ongoing communication with your healthcare team will help you manage and monitor proteinuria. Your doctors can help you incorporate all the proteinuria diet adjustments and lifestyle modifications we’ve recommended. Checking in with your doctors during routine check-ups will allow you to share the progress you’ve made and any changes in your symptoms. In addition to ensuring that you continue to receive the personalized care necessary for ongoing proteinuria management, your care team can help you recognize all the efforts you’re putting into managing your health—all those efforts will deserve to be applauded.
Empowering a Full and Vibrant Life
