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.
Soda is an unhealthy beverage because it's high in calories and sugar but low in vitamins and minerals. Coca-Cola is one example of a type of soda that's sugary and packed with calories, but Coke Zero is one alternative that is sugar-free.
Coke Zero is sweetened with a combination of aspartame and acesulfame potassium (Ace-K). Coke Zero is the same basic formula as classic Coke while Diet Coke is a different formula completely. Diet Coke is sweetened with aspartame only. There are unsubstantiated theories (at least by Coca Cola) that the unsuccessful release of Coke Two or new Coke was actually the formula for Diet Coke, just sweetened with the classic sugar combination.
