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.
While hardly an ideal beverage, Diet Coke may seem like a better choice than classic Coca-Cola. Diet Coke has no calories, sugar or carbohydrates, while a 12-ounce can of regular Coke has 140 calories and 39 grams of sugar. But Diet Coke contains ingredients that can cause undesirable side effects, especially when consumed in large quantities.
