About 1 pint (480 mL) of blood is taken when you donate. It takes about 10 minutes. The whole process-including answering questions and having a short exam-takes up to an hour. Donated blood is tested to make sure that it is safe to use.

Diet Coke made by Coca-Cola does not contain sodium benzoate, a change that was made voluntarily by the company in 2008. Coca-Cola's other drinks, including Fanta and Sprite, continue to use E211 in production. The company states that alternatives to E211 impact preservation and change the taste of the product.
