Americans with celiac disease are use to scouring their food labels for any mention of gluten, but they need to be equally careful when purchasing cosmetics.
As researcher Pia Prakash told The Huffington Post, body lotions and other beauty products often contain ingredients that stem from grains. However, cosmetics manufacturers aren't always forthcoming with this information, and many consumers don't think to check makeup products for gluten.
Prakash and her colleagues analyzed the websites of 10 cosmetics companies and found none of them disclosed the gluten content of products that contain the substance.
"Lipsticks and powders and foundations are probably the ones we worry about most, and you really never see ingredient lists on those products," Prakash explained.
Celiac is an intestinal disease that affects nearly 2 million Americans, or 1 in 133 people, according to the U.S. National Library of Medicine. Unfortunately, there is no cure for the condition outside of leading a gluten-free life, so it's crucial that any company that makes products containing the ingredient disclose that fact on their labels.
