Your “DNA Diet” in a Wristband
A new wristband has been designed that can suggest the best foods for you to eat according to your DNA profile. The new DnaNudge wristband is available in John Lewis, White City and Waitrose, Canary Wharf from the 9th December, and costing £120 offers a level of personalised health with the aim of tackling some of the biggest diseases of our world today.
The wristband could potentially solve the obesity crisis, as said by Inventor Chris Toumazou, Regius Professor of engineering at the Institute of Biomedical Engineering at Imperial College London. The wristband does not aim to provide healthcare, but more provides a personalised diet to promote health according to your genome. No DNA service currently on the market today offers this type of personalised diet instruction to influence real-time lifestyle choices.
To use the device you need only to take a saliva swab from your cheek and your DNA is sequences in one hour to be transferred onto the chip. Based on your genetics, a personalised list of what nutrients you should or shouldn’t eat is created. As some individuals are genetically predisposed to higher chances of obesity, this personalised list will contain the best nutrients to eat to prevent that from happening. After harvesting, the DNA device is destroyed, and the company does not keep your genome.
The wristband is connected to a smartphone application where your personal report can be viewed and inform you on your suggested caffeine, salt, saturated fat and sugar, calories, carbohydrate, and fat consumption intake, as well as your obesity risk. When in the supermarket you can simply scan food barcodes with your wristband to be advised on the food risk via a green, amber or red signal.
A trial test has been carried out in the NHS with promising results and is stirring up a lot of interest. The full report due to be published next year shows the success of one member of the trial who lost 8kg in six months by following the food recommendations given by DnaNudge. The trial subject kept off the total weight six months following.
DnaNudge is a hugely exciting, albeit optimistic, example of what advances in DNA sequencing technology can potentially do for personalised healthcare and curtailing the major disease crises that we are set to face.
