Mountain dew is one of the popular beverages in india.so many of the people are used to drink these beverages because of its cheap cost.i also used to drink mountain dew when ever I get tired.but now I want to avoid this drink because it contains caffiene.recently I heard that caffiene is so dangerous to health in such a way that it spoils the human digestive system.you can see if you rotate the bottle then these letters appeared contains caffiene. People who don’t know about the effects of caffiene are drinking these beverages.i suggest them to stop using mountaindew.
