The main job of the kidneys is to filter & purify the blood to detoxify the body. A combination of different symptoms is called a nephrotic syndrome, the cause of which can be traced back to damage to the kidneys, for example from diabetes mellitus . It does not define an independent clinical picture. If the kidney corpuscles can no longer perform their function, there is a strong loss of protein via the urine (= proteinuria) & this leads to water retention in the tissue (edema) & lipid metabolism disorders , high blood pressure , an increased susceptibility to infections due to the weakened immune system & a higher risk of thrombosis. The daily protein loss can be approx.> 30 g (individually different)

Why is nutritional therapy important?

Nutritional therapy supports you in optimally supporting your kidneys in their function. A diet adapted to protein and a limitation of the amount of table salt support diuretic therapy. Concomitant diseases such as lipid metabolism disorders and high blood pressure are of course taken into account in the therapy.

Furthermore, it is of the utmost importance to optimally supply your body with all of the fatty acids, micronutrients (vitamins and minerals), energy and protein that are important for you. Overall, the therapy aims to avoid foods that promote inflammation and at the same time consume plenty of anti-inflammatory foods. Weight reduction may be advisable if you are overweight / obese. If you are overweight, I recommend weight reduction and appropriate measures for this. Special attention is also paid to the supply of fluids; a drinking and eating log can provide information about a lack of fluid intake. Patients with kidney disease should discuss with their doctor whether they need to control their fluid intake.

You will learn how you can actively counteract inflammation in your body through foods that naturally have antifungal (against fungi), antibacterial (against bacteria), antiviral (against viruses) and antioxidant as well as immune-boosting properties - that is, natural antibiotics.

Functions of the kidneys:

  • Detoxification: urinary substances (creatinine, urea, uric acid), foreign substances, medication, environmental toxins

  • Keeping the water balance and osmotic pressure constant through electrolyte regulation

  • Hormone production: renin & erythropoietin, vitamin D activation in calcitriol

  • Maintenance of the acid-base balance: blood pH value: 7.4, supports the bicarbonate buffer (HCO3- + H + <-> H2CO3 <-> CO2 + H2O), H + excretion - regulation


  • Renin controls the filtration pressure

  • Filtration / d = 180 liters = 1.5 liters of urine / day

Kidney threshold of glucose: 180mg / dl / day

= max.absorption amount! -> more glucose is excreted as remainder (in diabetes mellitus)

Nephron (renal cortex) = functional unit

Nephrons consist of kidney corpuscles & tubules

1) Kidney corpuscles - primary urine formation 

  • Glomerulus-vessel unit (arteries) -> ultrafiltration

  • Baumann capsule (close-meshed filter, proteins get stuck)

2) renal tubules (tubular apparatus)

  • - reabsorption, secretion, concentration

  • Secondary urine formation (terminal urine)

  • proximal tubule (reabsorption: AS, glucose, water, electrolytes)

  • Henle loop (water)

  • distal tubule (water, electrolytes)

  • Connecting tubules (electrolytes)


Collection pipe (water reabsorption point) collects the secondary urine & guides it into the renal pelvis

Classification of your weight - definition and classification of weight in relation to height.

Special percentile curves apply to children and adolescents; the BMI cannot simply be used here.

BMI and interpretation: BMI: body mass index. Formula: Body weight in kg : (body height in m) 2

Underweight: <18.5

Normal weight: 18.5 - 24.9

Overweight = pre-obesity: 25-29.9

Obesity grade I: 30 - 34.9

Obesity grade II: 35-39.9

Obesity grade III:> 40 = per magna

Nutritional therapy

  • Anti-inflammatory nutrition as a basis, individually tailored to you

  • Individual energy & protein requirement calculation

  • Holistic therapy - do you have any comorbidities that need to be taken into account during the consultation?

  • Overall fat selection, how should it be designed

  • How many animal foods (e.g. meat products, milk and dairy products, cheese, fish products, eggs) are recommended?

  • What do I have to look out for when choosing animal foods?

  • How can I counteract inflammatory processes through diet?

  • Body weight: If you are overweight / obese, weight reduction may be recommended.

  • Avoid micronutrient deficiencies and mineral deficiencies & possibly counteract them with nutrient preparations

  • Prevent protein deficiency / excess protein

  • Which nutrients do I need in which ratio?

  • Get enough fiber (> 30 g / day) through natural foods, possibly fiber substitution

  • Sufficient fluid: total fluid per day: 30 - 35 ml per kg body weight and day. Attention, this is not just a drinking liquid. The liquid from food (approx. 500 - 800 ml) must still be subtracted from this, so that an amount of approx. 1.3 - 2 l of drinking liquid is created. In consultation with your doctor, a fluid limit may be necessary, this will then be taken into account.

  • add valuable anti-carcinogenic (anti-cancer) secondary plant substances

  • A selection of foods tailored to your needs with cooking and technical information (for breakfast, snacks, lunch, dinner)

  • Do you like to eat your warm meal in the evening? I am happy to cater to your individual situation and we will create a plan on how you can implement your wholesome diet into your everyday life.

  • which oils are good for me? What should I watch out for in relation to the anti-inflammatory diet?

  • How much fat spread (butter / margarine / vegetable fat) can I use and which products are recommended?

  • Get enough Omgea-3 fatty acids and essential fatty acids

  • How can I boost and support my metabolism with natural foods?

  • Coordinate sensible meal frequency for your individual case - meal allocation

  • Define the desired weight stabilization / normalization & the estimated period for this

  • what should be considered with beverages and alcoholic beverages?

  • How does exercise affect your body and thus also your diet?

  • Avoid blood sugar fluctuations

  • Sweetening foods - sweeteners, glucose, fructose, sugar and sugar substitutes, what can I use and in what quantities? How high is the respective sweetness of the different products?

  • what should be considered when baking and cooking?

  • what are cheap snacks / main meals

  • Eating out - what should you watch out for?

  • Vacation, boat trip or hospital stay, what should be considered?

  • Flatulence, bloating, diarrhea, constipation, vomiting, heartburn, loss of appetite, pain related to eating, what can I do about it?

  • Daily plans as an example for practical implementation in everyday life

  • Enjoyment training

  • Optimizing your eating situation

  • long-term maintenance of a jointly defined weight

  • Strengthen the stomach and intestines with natural foods

  • Additional therapy options

  • and other topics
