At-Home DNA Testing

Helix, 23andMe and other DNA sequencing services promise to tell you what foods you should and shouldn’t eat, how you should exercise, where your ancestors are from and much more, all based on an algorithmic analysis of your genes. And all you have to do to get this information is head to the local pharmacy or even Target to pick up a kit, or order it online. We take a look at the increasingly popular direct-to-consumer genetic testing industry, and what these tests can — and can’t — tell you about your health.
