Gesunde Nieren im Alter

Healthy kidneys in old age

The kidneys are vital organs that are often overlooked until problems arise. But a healthy kidney is crucial for overall well-being and health, especially as we age. In this article we will discuss why healthy kidneys are important and how you can optimally support them as you age, both through diet and sensible nutritional supplements.

Why a healthy kidney is important

The kidneys are extremely versatile organs that play a crucial role in the body. They are responsible for filtering the blood and removing waste products and excess fluid from the body to maintain healthy fluid balance. In addition, the kidneys regulate blood pressure, control electrolyte balance and support the production of red blood cells. A healthy kidney ensures that the body remains in optimal condition.

Nutrition tips for healthy kidneys

Diet plays a crucial role in maintaining healthy kidneys. Here are some important nutrition tips that can help you:

  1. Regulate fluid intake: Drink enough water to help the kidneys eliminate waste products, but avoid excessive drinking as this can put strain on the kidneys.

  1. Reduce salt consumption: A diet high in salt can increase blood pressure and put strain on the kidneys. Instead, choose fresh foods and reduce your consumption of processed foods.

  1. Limit Protein Consumption: Excessive protein intake can put strain on the kidneys. Be sure to consume protein in moderation and choose lean protein sources such as chicken, fish and tofu.

  1. Avoid excessive sugar: High sugar consumption can increase the risk of diabetes, which in turn can damage the kidneys. Reduce your sugar and sweets consumption.

  1. Eat foods rich in fiber: Fiber aids in digestion and can help efficiently remove waste products from the body.

Useful nutritional supplements to support the kidneys

Nutritional supplements can be a useful addition to your diet to support kidney function. Here are some supplements to consider:

  1. Omega-3 fatty acids: Omega-3 fatty acids can reduce inflammation and protect the kidneys.

  1. Vitamin D: Adequate vitamin D levels can promote kidney health.

  1. Coenzyme Q10: Coenzyme Q10 is a powerful antioxidant that can protect the kidneys from free radical damage.

  1. N-Acetylcysteine: This preparation can support the kidneys in detoxification and protect against oxidative stress.

  1. Curcumin (turmeric): Curcumin has anti-inflammatory properties and may improve kidney function.


A healthy kidney is crucial for health, especially as we age. You can optimally support your kidneys through a conscious diet, avoiding excessive salt and sugar, and taking targeted nutritional supplements. Remember that it is important to speak to a doctor or nutritionist before taking any supplements, especially if you already have kidney problems or are taking medications. Take care of your kidneys to maintain your overall well-being and quality of life.
