Diet Coke, a brand of Atlanta-based The Coca-Cola Co., partnered with actress Minka Kelly to support the National Heart, Lung and Blood Institute’s The Heart Truth campaign to raise awareness about heart health. New packages of the diet soda featured the hashtag #ShowYourHeart to encourage fans to share heart-inspired photos showing what “Show Your Heart” means to them. Each photo shared via Twitter or Instagram in February triggered a $1 donation from Diet Coke to the Foundation for the National Institutes of Health for as much as $100,000 in support of women’s heart health research programs.
