6.2 Under what conditions do we process your data?

We process your data in good faith and for the purposes set out in this privacy policy. In doing so, we ensure transparent and proportionate processing.

If, in exceptional cases, we are unable to comply with these principles, the data processing may still be lawful because there is a justification. A justification reason may be in particular:

  • Your consent;
  • the execution of a contract or pre-contractual measures;
  • our legitimate interests, unless your interests are overriding.

6.3 How can you revoke your consent?

If you have given us consent to process your personal data for specific purposes, we will process your data within the scope of this consent, unless we have another justification.

You can revoke your granted consent at any time by sending an e-mail to the address given in the imprint. Data processing that has already taken place is not affected by this.

6.4 In which cases can we share your data with third parties?

We may need to use the services of third parties or affiliates to process your data. We contractually ensure that third parties and affiliated companies comply with the requirements of data protection. We may also be required to disclose your data to authorities. We will only disclose your personal data if:

  • you have given your consent;
  • this is necessary for the fulfillment of the contract or the implementation of pre-contractual measures as well as for the enforcement of our rights;
  • there is a legal obligation to do so;

Under certain circumstances, your personal data may be transferred to companies abroad as part of the order processing. These companies are obligated to data protection to the same extent as we ourselves. The transfer may take place worldwide.

If the level of data protection does not correspond to that in the EEA area, we carry out a prior risk assessment and ensure contractually that the same level of protection is guaranteed as in the EEA area (for example, by means of the new standard contractual clauses of the EU Commission or other measures prescribed by law). If our risk assessment is negative, we take additional technical measures to protect your data.

Evidence-based management of nutritional deficiency

Content and purpose of this website is an independent website with the aim of providing support to healthcare professionals in the nutritional management in clinical practice:

  • NutriScreen: Recognised/validated and widely used screening tools to identify patients with manifest malnutrition or at increased risk of malnutrition.
  • NutriCalc: Calculation of protein and energy requirements using established formulas
  • NutriGo: Application-oriented practical recommendations for nutrition therapy in different clinical situations based on current guidelines
  • NutriRisk: Educational presentation for patients on the causes and consequences of malnutrition and the possibility to calculate the individual risk reduction using nutritional therapy.
  • NutriPro: Comprehensive product database
  • NutriBib: Reference work for leading, current and selected literature in the field of clinical nutrition


In Switzerland, 20-30% of hospitalised medical patients have manifest malnutrition or an increased risk of energy and protein malnutrition as assessed by the Nutritional Risk Screening (NRS 2002) score 1, 2. Compared to non-malnourished patients, malnourished patients show an increased rate of complications, a longer duration of hospital stay, a poorer quality of life, a loss of body function and an increased mortality 3. Malnutrition is often disease-associated, but can be specifically treated.

Goals of malnutrition management

The focus lies on early identification of patients at risk of malnutrition, in-depth assessment and immediate initiation of adequate individual (nutritional) therapy to improve and maintain functionality and quality of life, and to reduce complications and mortality. Nutritional management is a multi-professional team effort and should be carried out in cooperation between nursing, dieticians, doctors and other therapists.
