It would not matter. Lactose intolerance is due to lack of lactase, an enzyme that degrades lactose, in the intestine. Most of the symptomes is due the fact that the microflora is producing gaz and acid from the undigested lactose.

Allergies to lactose migth be different.

Thanks Ian, hadn't thought about it being a digestive problem. But I wonder why allergies don't cause complications since, now that you mention it, my sister has had three children and has allergies to milk which are so severe as to be life-threatening. I guess I should just ask her, but it's not an easy topic to work into everyday conversation.

Do allergies involve substances other than proteins

Thanks Ian, hadn't thought about it being a digestive problem. But I wonder why allergies don't cause complications since, now that you mention it, my sister has had three children and has allergies to milk which are so severe as to be life-threatening.

Lactose is a sugar. Allergies only involve proteins:

• What are allergens?
  
  Allergens are microscopic protein substances that are common and provoke allergic people to produce antidotes (antibodies).
  
  The most common allergy provoking substances are:
  
  
  • pollen from weeds, grass, flowers and trees
    
  • mould and mould fungus
    
  • house dust mites
    
  • fur from cats and dogs
    
  • medicines.

If she's allergic to milk, it's most likely to casein, which is a major milk protein. But, her allergy is to a non-human form of casein (presumably her allergy is to cow's milk). Unless her immune system was really screwed up, her body would be able to recognize the difference between a foreign protein and her own protein.
