What does soda do to the human body?

For one thing, soda contains a-a-a-a-lot of sugar. This is extremely bad for your health. Also, studies have been made to show that soda lowers your VO2 max (the amount of oxygen you can hold in your lungs). A lowered VO2 max lowers your physical ability. Diet soda is no better then real soda; it may even be worse for you. The sugar replacement used in diet sodas may cause illness like cancer.
