Food-health relationships for respiratory immune defence against infection and pollution driven inflammation
- 77% of Chinese consumers ranked ‘immune enhancement’
as important
- The outbreak of severe acute respiratory syndrome (SARS),
bird and swine flu coupled with Asia’s ageing population is driving the growth of the immune health F&B market
- Air pollution crisis across Asia presents a threat to human
health These perspectives suggest a potential high adoption rate for F&B solutions targeting respiratory immune defence

Building Immune Defence
Overall goal: Fast-track opportunities for NZ companies to develop foods and beverages with scientifically validated immune defence benefits
- Provide a causal relationship for the beneficial modulation
- f immune defence
- Identify associated nutrition responsive biomarkers
(established and new) of the physiological and immunological processes
- Examine the efficacy of these biomarkers to respond to food
interventions in mouse models

- Vaccination responses provide insight into the overall
efficacy of the co-ordinated function of a wide range of immune processes
- Increased numbers of individuals attaining acceptable
antibody titres is an appropriate nutrition responsive biomarker
- Immune responses vary widely from person to person
