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:
- 32% of men and 29% of women do not reach the recommended daily intake of the DGE. This means that almost every third person does not take up the recommended intake for vitamin C.
- The worst supplied men lack 61 mg of vitamin C. This represents a daily shortfall of 61% of the recommended intake.
- The worst-supplied women lack 57 mg of vitamin C. This corresponds to a daily shortfall of 57% of the recommended intake.
- Pregnant women(from the 4th month of pregnancy) have a daily excess requirement of 10 mg of vitamin C compared to non-pregnant women. Accordingly, the most poorly supplied pregnant women have a shortfall of 67 mg of vitamin C per day.
- Breastfeeding women have a daily excess requirement of 50 mg of vitamin C over non-breastfeeding women. Accordingly, the worst-supplied breastfeeding women have a shortfall of 107 mg of vitamin C per day.
- Smokers have a daily excess requirement of 50 mg of vitamin C over non-smokers.Accordingly, the worst-supplied male smokers have a shortfall of 111 mg of vitamin C. The worst supplied female smokers have a shortfall of 107 mg of vitamin C.
Since the intake recommendations of the DGE are based on the needs of healthy and normal-weight people, an individual additional need (eg due todiet, stimulant consumption, long-term medication, etc.) may be above the intake recommendations of the DGE.
