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.
The controversial New Coke, introduced in 1985, used a version of the Diet Coke recipe that contained high fructose corn syrup and had a slightly different balance of ingredients. In 2004, Coca-Cola introduced Coca-Cola C2, which it claims tastes much closer to Coca-Cola but contains half the carbohydrates. In 2005, the company introduced Coca-Cola Zero, a sugar-free variation of regular Coca-Cola. When Tab was released in 1963, the Coca-Cola Company refused to release a diet soda with the Coca-Cola name, fearing that its flagship brand might suffer.
