To secure a premium market position for a food, one of the most popular strategies is to claim an intrinsic human health-promoting ability.
Fruits in general have an inherent natural ‘health halo’, with some fruit often classed as ‘superfruits’ and/or ‘functional foods’, because they are rich sources of different bioactive substances that can provide human health benefits beyond just their nutritional content.
A lot of marketing emphasis has been placed on antioxidant activity of fruit compounds for health, but unfortunately this mode of action is not well supported by science. In recent years, other mechanisms are being revealed that can explain why fruits and their compounds are healthy.
Dr Roger Hurst leads a team of researchers focused upon providing health science evidence to support the development of new fruit food products. He will present on the team’s strategic targets, their multi-pronged approach to building the science evidence from chemistry, cell screening to human clinical studies, and will give insights into key data from various fruits, that is leading to the creation of new and improved fruit-derived functional food opportunities in NZ and Asia.
Dr Hurst has a biomedical health background through a career at the University of Toronto, Canada; the Babraham Institute, Cambridge, UK; and the Institute of Neurology, London, UK. Since joining Plant & Food Research (2007) he has developed an interest in phytochemical compounds and their role in modulating oxidative stress, inflammation, and immunity to aid tissue recovery and repair.
Max Harris is currently an Examination Fellow at All Souls College in Oxford. He completed a Master of Public Policy and Bachelor of Civil Law at the University of Oxford while on a New Zealand Rhodes Scholarship from 2012–2014, and a Law/Arts conjoint degree (with Honours in Law) at the University of Auckland from 2006–2010.
Professor John Townend will speak about lessons learned from recent and anticipated New Zealand earthquakes – including last year’s Kaikoura quake, one of the most complex earthquakes ever recorded.
Pests and subsequently, the use of pesticide to deal with pests, has long been a problem for the New Zealand Pip Fruit industry, especially when it sought to gain access into new, high-value export markets. However, since the mid 1990s, the work carried out by Dr Jim Walker and his team has contributed to more than a 90 per cent reduction in insecticide use (kg/ha) by local apple growers. This includes the introduction of new natural enemies through to the development of selective pest management and use of semio-chemicals (pheromones) to support greater use of biological control in apple orchards. The development and implementation of these innovative pest control tactics are now central to today’s pest management systems.
We have a remarkable capacity to mentally relive past events, imagine future ones, and even invent fictitious ones. This mental escape from the present allows us to plan our futures, deliberate on the past, and find inspiration in imagined scenarios. We can also transport ourselves into the minds of others, enhancing empathy and social understanding. Sometimes, our minds elude conscious control and wander in unpredictable ways, providing a potential source of creativity. Professor Michael Corballis will discuss the neuroscience and evolution of our mental excursions, and their implications for innovation, storytelling, and even language itself.
