Whole grain barley¹ and other products containing whole or milled barley are now allowed to claim that they are able cut the risk of heart disease, according to a decision by the US Food and Drug Administration.

"Consumers can expect to see whole barley and dry milled barley products such as flakes², grits³, flour, meal, and barley meal bearing the health claim," the FDA said.

To qualify for the health claim, the barley-containing foods must provide at least 0.75 grams of soluble⁴ fiber⁵ per serving of the food, the agency said.
