If I drink 1 red bull everyday (0, 25 l) and I work out in the gym 2 times a week, will it cause any health problems, if I in addition drink 0, 75l soda?

Energy Drinks. Your main concern with energy drinks and soda is the sugar and caffeine. While 1 energy drink a day may not seem like much, you are consumer a large quantity of sugar at one time. This is not good for your metabolism and health. Also, a consequence of energy drink caffeine can be cardiac arrhythmias. You should try to cut back on the energy drinks and continue to exercise.
