Excerpts:

• There is insufficient but very promising evidence to recommend the addition of probiotics to foods for prevention and treatment of allergic diseases, especially atopic dermatitis.
  
• Clinical improvement especially in allergic rhinitis and IgE-sensitized (atopic) eczema has been reported too.
  

Editor: How can data be "insufficient" but "very promising"?
