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:
- Without the use of iodized table salt, 96% of men and 97% of women do not reach the daily intake recommendation of the DGE for iodine.
- Assuming that iodized table salt is used for all recipes and mixes, 28% of men and 53% of women are still below the recommendation for iodine intake.
- It can be assumed that the actual iodine intake in the German population is between the values without and with consideration of iodized table salt.
- The worst supplied men lack (taking into account the iodine intake via iodized table salt) 74 µg iodine. This corresponds to a daily shortfall of 37% of the recommended intake.
- The worst supplied women lack (taking into account the iodine intake via iodized table salt) 109 µg iodine. This corresponds to a daily shortfall of 55% of the recommended intake.
- Pregnant women have a daily excess requirement of 30 µg iodine compared to non-pregnant women. Accordingly, the worst supplied pregnant women have a shortfall of 139 µg iodine per day.
- Breastfeeding women have a daily excess requirement of 60 µg iodine over non-breastfeeding women. Accordingly, the worst supplied breastfeeding women have a shortfall of 169 µg iodine 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, long-term medication, etc.) may be above the intake recommendations of the DGE.
