Functional Food Opportunities to Support Cognitive Fitness Dr Roger Hurst, Plant & Food Research | April 14 th 2016 Host Institution
Cognitive ‘fitness’ - maintained mental performance The Horticulture and Food Research Institute of New Zealand Plant & Food Research’s interests: » Cognitive function/performance » Concentration/alertness » Exercise performance/fatigue » Mood/Relaxation » Stress/Anxiety » Sleep prevention – not treatment
Consumer demand - Market opportunity Molecular targets 2- MAO inhibitors from plants Globally 85% 30% US population, consumers are 40% China actively interested, buying foods 32% actively that improve buying ‘concentration’ ‘Relaxation’ = 27% (USA) 45% (China) ‘Alertness’ = 27% (USA) 38% (China) (DataMonitor Consumer Survey 2011) Market value (2010) and growing… » USA = $541M - just sales ‘mood’ = $430M (2009) (Nutras World, Jan 2011) » Japan = $452M » India = $382M » China = $361M
Blueberries - The cognition fruit Dr James Joseph, Nutritional Neuroscientist, Tufts University, USA Dr Barbara Shukitt-Hale, Research Psychologist, Tufts University, USA Blueberries may help prevent Alzheimer's, new research suggests Scie ntists say the fruit is loaded with healthful antioxidants which could help prevent the effects of the increasingly common form of dementia .

Cognitive Fitness post High Intensity Training Aims: » Is cognitive fitness impaired post exercise/during fatigue/recovery » Is cognitive fitness improved by HIT » Does fruit consumption improve cognitive fitness post exercise, - improve cognitive recovery Pre training Post training High Intensity Interval Training measures measures Week 1 Week 3 Week 4 Week 2 Session 1 Session 2 Session 3 Session 5 Session 6 Session 4 VO 2 max VO 2 max 6 intervals 7 intervals 8 intervals 10 intervals 11 intervals 9 intervals Cognitive testing Cognitive testing Submaximal cycle Submaximal cycle Immediate cognitive testing after VO 2 max https://admin.joggleresearch.com/
