Editor’s note 2/6/2013: Pending an FDA decision, 23andMe no longer offers new customers access to health reports referred to in this post. Customers who received their health information prior to November 22, 2013 will still be able to see their health reports, but those who purchased after that time will only have access to ancestry information as well as access to their uninterpreted raw data. These new customers may receive health reports in the future dependent on FDA marketing authorization.
New rules issued by the US Food and Drug Administration earlier this month mean we may finally know what it means when a label on food we buy says “Gluten-Free.”
The new standards are hugely important for the more than 3 million Americans with celiac disease as well as many others who for other reasons may need to avoid gluten.
Gluten, a protein found in wheat, triggers a mistaken immune response in those with Celiac. This in turn can damage the lining of the small intestines and undermine the absorption of nutrients, ultimately causing symptoms that range from stomachaches to diarrhea and iron deficiency.
For those without Celiac who are also trying to avoid gluten — namely people who have allergies to wheat or simply a gluten intolerance — the new standards are also important.
Now anyone buying food with a “gluten-free” label, knows that means that to get that label the food must contain less than 20 parts per million of gluten.
