Drinks which have caffeine: found in a lot of soft drinks and in tea and coffee. Caffeine can cause your kidneys to make more urine, causing there to be less water in your blood. As you remember, less water in your blood makes it more likely that the blood cells in children with sickle cell disease will change into the sickle shape.

Soda: Too much soda can be bad for your teeth. Try to avoid soda!

(A little caffeine or soda is OK -- just be sure you also drink other fluids!)
