A London startup believes it can help you make healthier diet choices at the grocery store, using your own DNA.
DnaNudge collects your DNA through a cheek swab and sends data related to nutrition to a wristband.
Have a genetic predisposition to high blood pressure? Maybe the wristband will tell you to stay away from salty snacks.
Some scientists, however, say genetic makeup is just one of many factors in a healthy lifestyle.
DnaNudge's wristband was shown at the CES tech show in Las Vegas this week. The company says it destroys all DNA records after giving you the wristband.
