In the National Nutrition Survey II (NVS II, 2008), the dietary behavior of the population was investigated for Germany and it was shown how this affects the average daily nutrient intake with macro- and micronutrients (vital substances).
The intake recommendations (D-A-CH reference values) of the German Nutrition Society (DGE) are used as the basis for assessing nutrient supply. A comparison of the nutrient intake determined in the NVS II with the recommendations of the DGE shows for which micronutrients (vital substances) there is a frequent undersupply in Germany.
Regarding the supply situation, it can be stated:
- Niacin intake in men and women is above the intake recommendation in all age groups. Only 1% of men and 2% of women do not reach the recommended daily intake of niacin.
- Pregnant women (from the 4th month of pregnancy) have a daily excess requirement of 2 mg niacin compared to non-pregnant women. This intake amount is achieved by all age groups.
- Breastfeeding women have a daily excess requirement of 4 mg niacin over non-breastfeeding women. Correspondingly, the most poorly supplied breastfeeding women have a shortfall of 2 mg of niacin per day.
Since the intake recommendations of the DGE are based on the needs of healthy and normal-weight people, an individual additional requirement (eg due todiet, stimulant consumption, permanent medication, etc.) may be above the intake recommendations of the DGE.
