Scientific Method

Scientists have long suspected that high-fructose corn
syrup, used to sweeten soda, is one of the causes of
childhood obesity. In a recent study, researchers found
that mice that drank water with added fructose ate less
solid food, gained more weight and put on 90% more
body fat than mice that drank only water. Scientists
concluded that fructose may affect metabolism in a way
that favors fat storage.

The independent variable in this experiment is ___________.
