4. Keeping Blood Sugar in Check Diabetes is one of the leading causes of chronic kidney disease (CKD) worldwide. Persistently high blood sugar levels can damage… Alina Yasinskaya - September 3, 2025

Chronic kidney disease (CKD) affects nearly 10% of the global population, yet most people remain unaware until advanced stages due to its silent progression (National Kidney Foundation). The kidneys play a vital role in filtering waste and excess fluids from the blood, supporting overall health. Unfortunately, late detection is common, making early prevention essential for protecting these vital organs from irreversible damage.

1. Drinking Sufficient Water

Proper hydration is fundamental for optimal kidney function. Water helps the kidneys efficiently filter waste products and toxins from the blood, diluting urine and reducing the risk of harmful mineral buildup that can lead to kidney stones and other complications (National Kidney Foundation). When the body is dehydrated, the volume of blood flowing through the kidneys drops, making it harder for them to remove waste, and potentially causing long-term damage.

Chronic dehydration can lead to concentrated urine, which increases the likelihood of stone formation and can exacerbate existing kidney problems. Conversely, drinking adequate water keeps urine diluted and supports the kidneys’ self-cleaning process. The recommended daily water intake varies depending on age, activity level, and climate, but a general guideline is about 8 cups (2 liters) of water per day for most adults.

Practical cues for hydration include drinking when you feel thirsty, ensuring your urine is a light yellow color (a sign of good hydration), and increasing your intake during hot weather or physical activity. Listen to your body’s signals and consult your healthcare provider for personalized recommendations (Centers for Disease Control and Prevention).

2. Limiting Salt Intake

Consuming too much sodium, commonly found in table salt and processed foods, can significantly raise blood pressure, placing excess strain on the kidneys. Over time, high blood pressure can damage the blood vessels within the kidneys, reducing their ability to filter waste effectively and increasing the risk of chronic kidney disease (National Kidney Foundation). In contrast, a low-sodium diet helps maintain a healthy blood pressure, supports kidney function, and lowers the risk of kidney damage.

High-sodium diets are typically characterized by frequent consumption of packaged snacks, canned soups, cured meats, and restaurant meals. These foods often contain “hidden” salt that can quickly exceed daily recommended limits. The American Heart Association recommends no more than 2,300 mg of sodium per day, with an ideal limit of 1,500 mg for most adults (American Heart Association).

To limit salt intake, read nutrition labels carefully for sodium content, choose fresh or frozen fruits and vegetables, and use herbs or spices for flavor instead of salt. Preparing meals at home gives better control over sodium levels and supports long-term kidney health.

Diabetes is one of the leading causes of chronic kidney disease (CKD) worldwide. Persistently high blood sugar levels can damage the delicate blood vessels in the kidneys, impairing their ability to filter waste and fluid from the body (Centers for Disease Control and Prevention). Over time, this can lead to a condition known as diabetic nephropathy, which often progresses silently until kidney function is significantly compromised.

Research has shown that tight glycemic control—maintaining blood sugar within recommended targets—substantially lowers the risk of developing CKD or slowing its progression (National Institutes of Health). Monitoring your blood glucose regularly, following a balanced diet, and taking prescribed medications are essential strategies. Physical activity and weight management also play important roles in preventing spikes in blood sugar.

Be attentive to warning signs of poor glucose control, such as frequent urination, increased thirst, unexplained fatigue, or blurred vision. If you notice these symptoms, consult your healthcare provider for evaluation and potential adjustments to your treatment plan. Early intervention is crucial to protecting your kidneys from irreversible damage.

While protein is essential for building and repairing tissues, overconsumption of animal protein—such as red meat and processed meats—can put significant strain on the kidneys. Excess protein increases the kidneys’ workload by producing more nitrogenous waste, which must be filtered out of the blood. Over time, especially in individuals with existing kidney concerns, this heightened demand may contribute to declining kidney function (National Kidney Foundation).

Choosing lean protein sources such as poultry, fish, eggs, and low-fat dairy can help reduce this strain. Even better, incorporating more plant-based proteins—like beans, lentils, tofu, and quinoa—provides essential nutrients without the saturated fat and cholesterol found in many animal products. Several studies have shown that plant proteins are associated with a lower risk of CKD progression compared to diets high in animal protein (National Institutes of Health).

Portion control is also important: aim for about one-quarter of your plate to be protein, or roughly the size of your palm per meal. Balancing your protein intake throughout the day and pairing it with plenty of vegetables and whole grains can further support kidney health.

6. Avoiding Processed Meats

Non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, naproxen, and aspirin, are popular over-the-counter pain relievers. However, frequent or long-term use of NSAIDs can significantly impair kidney function by reducing blood flow to the kidneys and disrupting their ability to remove waste and maintain fluid and electrolyte balance (National Kidney Foundation). Chronic NSAID use has been linked to an increased risk of acute kidney injury and, over time, the development or progression of chronic kidney disease.

Occasional, short-term NSAID use is generally considered safe for most healthy individuals, especially at recommended doses. The risk of kidney damage rises substantially with chronic use, higher dosages, or preexisting kidney conditions. Individuals with diabetes, hypertension, or heart failure are particularly vulnerable to NSAID-induced kidney damage (National Institutes of Health).

For safer pain management, consider alternatives such as acetaminophen (when appropriate), physical therapy, gentle exercise, or relaxation techniques. Always consult your healthcare provider before starting or continuing any pain medication, especially if you have risk factors for kidney disease.

Full-fat dairy is higher in saturated fat and calories, which can contribute to weight gain, high cholesterol, and increased risk of cardiovascular disease—all factors that burden the kidneys. In contrast, low-fat dairy provides essential nutrients like calcium and protein without the excess fat, making it a healthier choice for most individuals (National Kidney Foundation).

Another consideration is phosphorus content. Dairy products, especially some processed cheeses and yogurts, can be high in phosphorus—an issue for those with chronic kidney disease, as the kidneys may struggle to remove excess phosphorus from the blood. Low-fat and nonfat dairy options typically have less saturated fat and, in some cases, reduced phosphorus content, but it’s still important to check labels and choose products wisely (National Institutes of Health).

When shopping, look for milk, yogurt, and cheese labeled “low-fat” or “nonfat,” and compare nutrition facts for phosphorus and sodium amounts. Unsweetened versions are best to avoid added sugars. Moderation is key, and people with kidney concerns should consult their healthcare provider or dietitian for tailored recommendations.
