Día Mundial del Riñón: Un Llamado a la acción
The past Thursday marked World Kidney Day, a date that reminds us of the importance of caring for this organ that is as invisible as it is vital. It is no wonder, then, that chronic kidney disease (CKD) continues to grow in our country, where it already affects 15% of the population, according to data from the Spanish Society of Nephrology.
The good news is that prevention is absolutely possible. Early detection and treatment can significantly delay the progression of kidney disease.
Prevención de la Enfermedad Renal Crónica (ERC)
Chronic kidney disease (CKD) is a growing concern, affecting a significant portion of the population. However, proactive measures can make a substantial difference.
According to Dr. Emilio Sánchez, president of the SEN, early detection and treatment of impaired kidney function can delay the need for dialysis or transplantation by up to 20 years. This can be achieved thru simple blood and urine tests to measure plasma creatinine (and calculate glomerular filtration) and albumin in urine.
«Con detección precoz y tratamiento temprano del deterioro de la función renal se puede retrasar hasta en 20 años el ingreso en diálisis o trasplante, y eso se puede lograr con sencillos test de sangre y orina para medir la creatinina plasmática (y calcular el filtrado glomerular) y la albúmina en orina»
Dr. Emilio Sánchez, presidente de la SEN
The Role of Diet in kidney Health
Diet plays a crucial role in both preventing and managing kidney disease. With millions affected, but manny unaware, dietary choices have a profound impact.
Dr. Borja Quiroga, a specialist in the Nephrology Service at the Hospital Universitario de La Princesa (Madrid), emphasizes the importance of nutrition:
«La alimentación es el primer escalón en la preservación de la salud del riñón y en evitar la progresión de una enfermedad renal en las personas que la padezcan. Existe evidencia científica en la que se muestra que la dieta mediterránea es beneficiosa a todos los niveles orgánicos, incluyendo los riñones. Por ejemplo, la reducción en el consumo de sal o de ultraprocesados conduce a unos riñones más saludables, mientras que una dieta basada en frutas, verduras, que evite los fritos o las grasas es saludable para todo el organismo y preserva la salud de los riñones. Sin olvidar el café (incluso descafeinado), ya que los compuestos del mismo tienen propiedades muy saludables»
Dr. Borja quiroga, especialista del Servicio de Nefrología del Hospital Universitario de La Princesa (Madrid)
A mediterranean diet, rich in fruits and vegetables, and low in salt and processed foods, is beneficial for kidney health.
Nutritional Approach to Kidney Disease
Once kidney disease is diagnosed, a tailored nutritional approach becomes essential.
Dr. Quiroga advises that recommendations for patients with kidney disease are similar to those for maintaining healthy kidneys. specifically, individuals with kidney disease should be more careful with their consumption of salt and phosphorus, as both can exacerbate complications.
Key recommendations include:
- Limiting salt intake to manage hypertension and fluid retention.
- Controlling phosphorus intake to prevent accumulation in the blood, which can lead to cardiovascular events.
Dr.Quiroga, co-author of the book “Por mis riñones que hoy como bien” with Michelin-starred chef Miguel Cobo, notes that specific dietary guidelines may be beneficial for certain kidney conditions:
- patients with kidney stones (lithiasis) should reduce oxalate in their diet.
- Individuals with urinary infections may benefit from increased cranberry intake due to its antimicrobial properties.
Debunking Myths: Hydration and Kidney Function
The kidneys filter various substances, leading to the common myth of needing to drink at least two liters of water daily.
Dr. Quiroga clarifies:
«Para eliminar el exceso de tóxicos, necesitamos beber cierta cantidad de agua, pero esa cifra rígida no debe ser tomada como una medida global. Ahora bien, en situaciones en las que hagamos deporte, de exceso de sudoración o de pérdidas adicionales (diarrea), se debe incrementar el consumo hasta lo que marque la sed.Y no debemos olvidar que el riñón es más que una depuradora de desechos y también regula la anemia, el calcio o el ácido úrico»
Dr. Borja Quiroga
While adequate hydration is necessary, the specific amount should be adjusted based on individual needs and circumstances, such as exercise or illness. The kidney also regulates anemia, calcium, and uric acid.
Kidney Health and Longevity
The health of your kidneys can significantly impact your longevity. They contain a protein called klotho, which helps eliminate excess phosphorus.
Dr. Quiroga warns:
«Contienen una proteína denominada klotho cuya función principal es deshacerse del exceso de fósforo. desde hace 30 años sabemos que la deficiencia de esta proteína se asocia a un envejecimiento precoz, principalmente de los vasos sanguíneos y del cerebro. Por ello, es vital conservar la función renal, ya que cuando esta se deteriora, se pierde el elixir de la eterna juventud klotho, y nos hacemos mayores antes de lo que corresponde a nuestra edad biológica»
Dr. Borja Quiroga
Maintaining kidney function is vital because when it deteriorates, the loss of klotho accelerates aging, especially in blood vessels and the brain.
Intermittent Fasting as a Strategy for Kidney Health
Intermittent fasting presents itself as an alternative to keep kidneys at bay. It helps restore the function of mitochondria, which are responsible for taking energy from food and storing it.
Dr. Quiroga explains:
«Gracias a él restauramos la función de las mitocondrias, encargadas de coger la energía de los alimentos y almacenarla. Si comemos continuamente, estas empiezan a canalizar la energía de manera patológica; se sobrecargan y generan estrés oxidativo, precursor de enfermedades reumatológicas, renales, cardiacas o neurológicas. Con el ayuno dejamos descansar a las mitocondrias restaurando sus funciones energéticas, de ahí su beneficio»
Dr. Borja quiroga
Intermittent fasting allows mitochondria to rest and restore their energy functions, which can be beneficial for overall health.
