The American Heart Association has made official what some onion growers have been saying for years by awarding its Heart-Check mark to onions grown in Idaho and eastern Oregon.

The Heart-Check mark signifies that a food has been reviewed by the association and meets criteria for good heart health, such as being low-fat, low-cholesterol and low-sodium, according to the group’s website.

This summer the Idaho-Eastern Oregon Onion Committee, Parma, Idaho, received the OK from the American Heart Association to use the Heart-Check on members’ onions. The mark can be used on Spanish sweet reds, yellows and whites, said Sherise Jones, committee marketing director.
