Sweetened soda is losing its popularity in the U.S. but not soon enough for health officials who believe that high-fructose corn syrup is a serious threat to our health.

One of the problems with the ingredient is that it transforms into fatty acids, some of which stay in the liver while the rest of it filters into the blood stream.

Among 22 students who volunteered for the experiment, half move around half of much as they normally did on a daily basis while the other participants doubled their activity, namely walking about 12,000 steps a day.  Meanwhile, everyone drank two fructose-laden sodas for a total of 500 calories.

The study also conducted metabolic and health tests before and after the two week experiment and found, to some dismay, that the group who didn't walk as much experienced higher concentrations of very low density lipoproteins, a type of bad cholesterol that builds up on the walls of arteries.

The latest study finds that cutting out high-fructose corn syrup is the best option but if people feel the need to drink soda, they recommend plenty of exercise to help offset its effects.
