Crohn’s disease patients may be unnecessarily avoiding dairy products

1st September, 2011

Dietician Ms Deborah Nolan, seconded to work with Nutrigenomics New Zealand for 6 months, was disturbed to learn that approximately half of the Crohn’s disease patients in Auckland were avoiding dairy products, not because they had been diagnosed with a specific allergy but often because they were being given poor nutritional advice. 

Reduced intake of the nutrients in dairy products, especially calcium and vitamin D, could exacerbate the osteoporosis that commonly accompanies the disease. Deborah’s work is now published in the Journal of the American Dietetic Association.

Deborah was seconded through an Australian Government Endeavour Fellowship, intended to foster collaborations between Australia and New Zealand.
