Chronic Kidney Disease (CKD) is a condition that affects millions of people, yet it often goes unnoticed until it reaches advanced stages. Heather Smith, a registered dietitian and kidney nutrition specialist, recently led a class to raise awareness about CKD, discussing its risk factors, early detection, and nutritional strategies for prevention and management.

Why Focus on Chronic Kidney Disease?

Many people are unaware of how common CKD is. Statistics show that one in seven adults in the U.S. has some stage of CKD, with about 40% of them unaware of their condition. CKD can lead to end-stage renal disease, requiring dialysis or a kidney transplant. However, early detection and dietary management can significantly slow the progression of the disease.

Who Is at Risk?

Certain conditions and lifestyle factors increase the risk of CKD, including:

• Diabetes and high blood pressure (the leading causes of kidney failure)
• Heart disease
• Obesity and smoking
• Family history of kidney disease
• Frequent use of kidney-damaging medications
• Being Black, Native American, or Asian American
• Aging and structural abnormalities in the kidneys

Many people do not experience symptoms in the early stages, making regular blood tests crucial for early detection. A simple blood test measuring estimated glomerular filtration rate (eGFR) can help determine kidney function. If eGFR is below 60, further evaluation is needed.

Key Nutritional Considerations for CKD

Diet plays a crucial role in managing CKD. Heather highlighted four key areas: protein, sodium, phosphorus, and potassium.

Protein: Finding the Right Balance

While protein is essential for the body, excessive protein intake can strain the kidneys. Individuals with CKD should moderate their protein intake based on their disease stage. The recommended range is 30-70 grams per day, significantly lower than the intake for healthy individuals.

Heather also emphasized the importance of prioritizing plant-based protein sources, as animal protein can increase acidity in the blood, contributing to metabolic acidosis. Eating more fruits and vegetables helps maintain a healthier pH balance.

Sodium: Moderation Is Key

Sodium can contribute to high blood pressure, which accelerates kidney damage. While some sodium is necessary, excessive amounts can lead to fluid retention and increased strain on the kidneys. Heather recommends limiting processed foods and cooking at home to control sodium intake. She suggests aiming for 700 mg of sodium per meal and using unrefined salts like Celtic sea salt instead of regular table salt.

Phosphorus: The Hidden Risk

High phosphorus levels can lead to complications like bone disease and heart problems in CKD patients. Unlike naturally occurring phosphorus in foods like dairy, meat, and beans, phosphate additives in processed foods are absorbed at nearly 100%, making them particularly harmful. Heather advises checking ingredient labels for words containing "PHOS" and opting for whole foods instead.

Potassium: Individualized Approach

Potassium helps regulate heart function and muscle contractions, but too much can be dangerous for CKD patients. While many doctors recommend potassium restrictions, Heather notes that this is not always necessary. A potassium level over 5.0 may require dietary adjustments, but otherwise, she encourages CKD patients to continue eating fruits and vegetables for their many health benefits.

Iron and Micronutrients

CKD can lead to iron-deficiency anemia, causing fatigue, headaches, and restless legs. To improve iron absorption, Heather suggests pairing non-heme iron sources (such as beans and seeds) with vitamin C-rich foods (like strawberries or bell peppers). She also touched on the importance of vitamin D, omega-3s, iodine, calcium, zinc, and selenium, all of which play essential roles in overall health.

The Importance of a Whole Foods Diet

Heather strongly advocates for transitioning from a standard American diet to a whole foods diet. Not only does this help manage CKD, but it also supports overall health by reducing processed food intake and improving nutrient quality. She also aligns with GoldCare’s dietary recommendations, which emphasize real, nutrient-dense foods.

Final Thoughts

Heather concluded the class by encouraging participants to take control of their kidney health through early detection and dietary changes. She also offers personalized guidance for those looking to transition to a whole foods diet or manage CKD effectively.

If you or someone you know is at risk for CKD, consider reviewing blood test results for early signs and making simple but impactful dietary adjustments. Small changes today can prevent serious complications in the future.
