Digestive Health

Our research focus

Gastrointestinal dysfunction makes it hard for the body to absorb nutrients. Discomfort and inflammation are other unwelcome gut-related effects. Diet is a factor but the underlying mechanisms are poorly understood, especially when it comes to making cause-and-effect claims for particular foods. A pivotal weakness is the lack of understanding of Irritable Bowel Syndrome (IBS), which is a common problem in Asian populations. This prevents New Zealand food producers making valid claims for gastrointestinal health benefits. To address this, High-Value Nutrition’s Digestive Health programme is conducting in-depth research, primarily via access to a large cohort of patients with IBS who are precisely phenotyped. Clinical evidence shows a food-health relationship for gut function and comfort using accepted biomarkers. The characterisation and description of biomarkers creates opportunities for  innovative food and beverage products from New Zealand. The Digestive Health programme is also working alongside industry, in a co-funded research project with a2 Milk Company.

a2 Milk for digestive health

Dr Matthew Barnett, Senior Research Scientist at AgResearch Ltd, and Dr Andrew Clarke, Chief Scientific Officer at a2 Milk, are working on a project to research whether milk from a2 cows prevents intestinal inflammation, and are therefore suitable for people who don’t consume milk due to intolerance symptoms.
