Kidney health

Strengthen the body's filtering function – 10 practical everyday tips

Your kidneys perform an invisible daily feat: they filter litres of blood, remove toxins and protect your body from internal disorder. But this quiet work also makes them vulnerable. Too little water, too much salt, stress or unconscious habits can gradually strain them without you noticing right away. How would you recognise that your kidneys are under pressure?
  • Consciously monitor blood sugar levels in daily life

Pay attention to regular, stable meals and have your blood sugar checked regularly, especially if you have an increased risk. The long‑term value (HbA1c) should be within the recommended range to support a healthy metabolic balance.

  • Be intentional about exercise and lifestyle

Incorporate regular activity into your daily routine, for example with short walks or taking the stairs. In addition, mindful stress management, quitting smoking and moderate alcohol consumption can contribute to overall physical balance.

  • Drink enough fluids

Make sure to drink water regularly throughout the day to support the body's elimination and filtration functions. Water and unsweetened herbal teas are particularly suitable because they do not place an extra burden on the body.

  • Use ginger regularly

Use fresh ginger in tea, smoothies or warm dishes. The antioxidants and anti‑inflammatory compounds it contains have been linked in studies to positive effects on various bodily functions.

  • Minimise unhealthy fats where possible

Limit consumption of highly processed or fatty foods, as these can place additional strain on the body. Instead, opt for fresh, simple dishes made with high‑quality ingredients.

  • Reduce salt intake intentionally

Try to lower your everyday table salt intake by avoiding highly processed foods and cooking from scratch. Season with herbs and spices instead to enhance flavour naturally.

  • Eat cruciferous vegetables regularly

Eat broccoli, cauliflower, kohlrabi, white cabbage, Brussels sprouts or Chinese cabbage on a regular basis. These vegetables contain valuable minerals such as iron, calcium, selenium, copper, manganese and zinc, as well as glucosinolates.

  • Use olive oil as a high‑quality fat source

Use olive oil to dress salads or to refine vegetable dishes. The oleic acid it contains can help support normal blood pressure and is an important part of a balanced diet.

  • Include apples regularly in your diet

Eat apples regularly because they contain pectin. Pectin can support various metabolic processes in the body. For example, you can have an apple as a snack or chop it into muesli or salad.

  • Use medications with care

Handle medicines carefully and take them only when needed and at the recommended dose. Some medications can place a greater or lesser burden on the body, so a cautious and restrained approach is especially important.
