We know that people with Chronic Kidney Disease need to watch different aspects of their diet. Sodium, a mineral commonly found in table salt and many processed foods, plays a significant role in fluid balance and blood pressure regulation. However, when your kidneys are not working at 100% it becomes important to manage the amount of sodium ingested each day. It is important to prevent any health complications that can happen over time.
THE ROLE OF SODIUM IN CKD:
Fluid Balance Regulation: Sodium exerts its influence on fluid balance by regulating the movement of water across cell membranes. In individuals with impaired kidney function, the ability to excrete excess sodium may be decreased which can lead to fluid retention and edema.
Blood Pressure Control: High sodium intake is strongly associated with hypertension, a common complication of CKD. Elevated blood pressure can accelerate kidney damage, worsening the progression of CKD and increasing the risk of cardiovascular events.
Electrolyte Imbalance: CKD often disrupts the body's electrolyte balance, including sodium levels. Abnormal sodium levels can contribute to symptoms such as fatigue, confusion, and muscle weakness.
STRATEGIES TO LOWER SODIUM INTAKE
Stay away from processed foods as much as possible. This includes reducing the consumption of high-sodium foods such as processed snacks, canned soups, and processed meats. Instead, focus on fresh or frozen fruits, vegetables, and whole grains, which are naturally lower in sodium.
Read your food labels. Paying attention to serving sizes and sodium content per serving can help in making informed choices. Focus on foods that provide less than 15% of the Daily Value (D.V.).
Limit how much salt you use when you are cooking. For added flavor, make sure to add herbs, spices, and vinegar to your food.
Make your own vegetable or chicken broth instead of using store bought broth.
