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
