Have you been thinking about improving your diet, but don't know where to start?
There might be another app to help you with that, this time using your DNA.
DNANudge has opened in London's Covent Garden.
It can analyze your DNA in under an hour - and fit you with a wristband - that will "nudge" you towards healthier shopping choices based on your lifestyle.
Here's how it works: A cheek swab maps your genetic makeup, they say in about an hour, to identify any predisposed conditions or diseases.
The customer can then scan a food in a supermarket and instantly find out if its recommended.
DNANudge's CEO says his investment in the app comes from a personal place.
(SOUNDBITE) (English) PROFESSOR CHRIS TOUMAZOU, CEO DNANUDGE SAYING: "I've got the gene for hypertension so I've got to be very wary of salt.
Salt is one of my issues and what's very interesting actually is that there is less salt in salted peanuts rather than dry roasted peanuts, for me.
Which means that since I love peanuts over a year I could potentially save about 2kg of salt not entering my bloodstream without even realizing it." When you scan a barcode, the DNANudge app or band will either show "green" for good to go, or "red" - in which case the app will suggest healthier alternatives.
The DNABand also monitors your activity, or lack thereof.
So an item that was green one day may be amber the next if you have been sedentary for too long before scanning it.
Be warned full package isn't cheap: The company charges $154 for the DNA test, wristband, and the phone app.
