Northumbria University psychologist to introduce diners to the science behind food and drink

Diners will discover how the food on their plate can impact their brain function at a special dining experience during the British Science Festival in Newcastle.

Northumbria University biological psychologist, Professor David Kennedy, has teamed up with Newcastle restaurateur David Kennedy to introduce diners to the science behind their food and drink at an event called DK2: A Cerebral Celebration of Food and Science.

Blending the academic with the gastronomic, the dinner features a menu created from foods that research has found to have an effect on how the brain functions.

DK2 takes place at The Bridge restaurant in the Vermont Hotel, Newcastle, on Sunday 8 September.

Between each of the carefully chosen courses Professor Kennedy, Director of Northumbria's Brain, Performance and Nutrition Research Centre (BPNRC), and colleague Emma Wightman, lecturer in biological psychology, will explain to diners how the food they are eating affects the brain, drawing on the research undertaken at Northumbria and elsewhere. Chef Kennedy will describe how the courses have been prepared.

On the menu is heritage carrot soup with pine nuts and walnuts, escabeche of local mackerel, Northumbrian lamb with various kales, cauliflower and garlic, beetroot and chocolate cake, with foraged blackberries and crème fraiche. Wine, coffee and tea will also be served.

Professor Kennedy will describe the benefits of each of the ingredients:
• Carrots - carotenoids in carrots are converted into Vitamin A, required for the brain's physiological processes;
• Walnuts - rich in melatonin and essential fatty acids, walnuts might be a 'superfood' of the future, aiding brain function
• Chocolate & blackberries - contain cocoa-flavanols, anthocyanins and other polyphenols, which increase blood flow, potentially leading to improved cognitive performance.
• Kale & beetroot - contain nitrate which is converted to nitric oxide, a key neuro-modulator and signalling molecule that dilates blood vessels in the brain producing increased blood flow.
• Wine - resveratrol polyphenol, found in grapes and red wine, increases blood flow in the brain during task performance.
• Coffee & tea - caffeine increases alertness and concentration whilst L-theanine, an amino acid found in tea, modifies the negative effects of caffeine on blood pressure and may potentiate its cognitive effects.

Professor Kennedy said: "In Western society we tend to eat a lot of high energy but nutritionally poor foods. Therefore we have deficiencies in vitamins and other micronutrients. The best way to get these is by eating good healthy food. These foods all have a positive effect on brain function.

"The best way to get the things the brain needs to function well is by eating a balanced diet but, where people find this difficult, vitamin supplements can help to fill in the gaps. Our research work at Northumbria University looks at supplements and their effect on brain function.

"The message we want diners to take away from this session is the importance of eating more of the healthy foods in their daily diet. This event will also give them tips on how to cook them too!"

During the event Emma Wightman, lecturer in biological psychology at Northumbria, will demonstrate the brain imaging technique using near-infrared spectroscopy - a non-invasive assessment of brain function using infrared light to detect changes in blood haemoglobin concentrations associated with neural activity.

She will also describe her own research showing that red wine - polyphenol resveratrol - increased cerebral blood flow in study participants.
