Nutrition survey of the adult population in Germany

National Nutrition Monitoring (nemo) is composed of several survey units. Nemo was launched with online surveys of adults, children and adolescents. Now, the next unit is starting: a study during which the participants are interviewed by phone and in person and given a physical examination. Amongst other things, data is being collected on food consumption, eating habits, the use of dietary supplements and body measurements. Biological samples are taken to determine the levels of certain nutrients, such as Vitamin D and iodine. Adults between the ages of 18 and 80 are examined – in another survey unit, children from the age of one will be surveyed. 

During the nemo study unit that has now begun, a random sample of more than 3,000 adults will be examined and asked about their nutrition up to June 2027. 

The aim of the survey is to acquire up-to-date data on the food consumption, nutrient intake and nutrient status of the adult population in Germany.

The nemo study is being conducted at 120 randomly selected municipalities in Germany. Important criteria for selection include population density in the federal states and the size of communities. The randomly selected study participants are drawn from the address lists held by the Residents’ Registration Office and invited to participate by letter.

Participation takes place at home and comprises the following three parts:

1. During the first home visit, interviewers ask participants about sociodemographic characteristics (e.g., size of household or educational level), their nutritional situation (e.g., vegetarian or vegan diet, purchase of organic products) and their physical activity. Height, weight and waist measurements are also recorded.
2. In a period of up to six weeks, two telephone interviews follow. Here, the participants are asked in detail about their current food consumption and use of dietary supplements.
3. After the two telephone interviews, the participants receive another home visit – this time, from medical professionals who take urine and blood samples to determine their nutritional status (blood: iron, folic acid, selenium, Vitamin D, Vitamin B12; spontaneous  urine: iodine, sodium, potassium).

If they wish, participants can receive selected results of their nutrient status as well as a small gift and an allowance of 55 euro if they complete all parts.

The Max Rubner-Institut has contracted the market research institute Oracle Life Sciences with conducting the dietary interviews and home visits.

The results from the questionnaires, anthropometric measurements and biological samples are expected to be available starting in early 2028; results from the dietary data in mid-2028.
