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.
Diet Coke and most other diet soft drinks do not contain sugar. Sugar is a type of carbohydrate, and carbohydrate is the nutrient that has the most effect on blood glucose. Most diet soft drinks are sweetened with non-nutritive or non-caloric sweeteners such as aspartame, acesulfame-K and sucralose. These sweeteners contain no calories or carbohydrate.
