|Experimental: Phospholipid enriched dairy product||
Dietary Supplement: milk phospholipid
The patients will consume daily 250 mL of a dairy product, which is enriched with 3 g of milk phospholipids.
|Placebo Comparator: dairy product||
Dietary Supplement: diary product
The patients will consume daily 250 mL of a common dairy product.
Based on the facts, that on the one hand milk phospholipids are characterized by a high sphingolipid content and on the other hand a disturbed sphingolipid metabolism in the epidermis of patients with atopic dermatitis was verified, a double blinded, controlled, randomized, cross-over study with a daily supplementation of 3 g milk phospholipids to subjects with a mild to moderate atopic dermatitis will be conducted.
Forty patients will be randomized between two groups of each 20 patients. After an individual checkup and a run-in period of 2 weeks, the one group will receive the phospholipid enriched dairy product and the second group will be given a placebo dairy product over two month. A wash out-period of 4 weeks will follow, and the patients will consume the contrary dairy products over two month after a 2-week run-in period again.
