New index evaluates nutrients: How healthy is canteen food?

Written by

Here you find the doctoral student’s profile of Frank Forner. He published results of his doctoral studies at Martin Luther University Halle-Wittenberg and shared the research more widely with a press release.

About the author:

F. Forner (second from right) with the working group of the Back-to-the-Roots project, a joint project of MLU with TU Ilmenau, in the framework of which the Ecoviant app was developed.
  • Frank Forner ORCHID ID, ResearchGate

  • Institute for Agricultural and Nutritional Sciences (link), MLU

Field(s) of expertise during doctoral studies:

  • Bioactive plant compounds 
  • Nutrient databases
  • Food assessment with algorithms

Curriculum Vitae

  • Further development of the nutriRECIPE-Index
  • Application in Ecoviant-App
  • Doctoral studies in the group Human Nutritional Sciences of 
    Prof. Dr. Gabriele Stangl at MLU
  • Master in Nutritional Sciences at MLU in 2013

Challenges, rewards and contribution

Q: What was your most important contribution to the publication?
A: The development of a database for bioactive plant compounds with more than 9479 data points for 172 plant-based raw products and connecting these data to the German Nutrient Database (Bundeslebensmittelschlüssel) was a milestone. Furthermore, the extension of the data to processed foods was necessary for evaluating the canteen recipes with the nutriRECIPE-Index.

Q: What was challenging and what was a rewarding moment during your work presented in the publication?
A: The connection of real recipe data to the German Nutrient Database and the following calculation of all nutrients was quite a lot of challenging work. The most rewarding outcome for me was that nutriRECIPE-Index will be used to assess the health impact of foods in the Ecoviant-App, which also assesses the environmental impact of foods.

Significance of publication

A new index evaluates the nutrient content of meals more accurately than comparable evaluation systems. Researchers at Martin Luther University Halle-Wittenberg (MLU) have developed the nutriRECIPE-Index and used it to evaluate the nutrient density of 106 canteen meals. For the first time, they also include health-promoting bioactive plant substances in their evaluation system.
