There's a solid chance that Glutenfree Singles is the world's healthiest dating site. The site caters solely to those who live life free of gluten, be it for medical reasons or personal choices. In addition to dating the site is also meant to be used to help gluten-free folks network and communicate with one another.
Glutenfree Singles is free to join and hopes to cater to the three million people who suffer from celiac disease (an intolerance to gluten) and those who just want to live a healthier lifestyle. While the website is targeted primarily at those already living without gluten, it also welcomes those who want to make the switch. Recently there has been a boom in sites such as Glutenfree Singles which seek to cater to a niche group of singles. If sea captains can have their own dating site, why can't gluten-free people?
