do you drink let your kids drink coke?? and do u drink it??

i drink coke. and i let my kid drink it. what's the problem with that? some said coke isn't good for your health, but as long as we drink it occasionally, i think it's not a big issue. it's the same as some parents who won't let their kids eats snack because some addictive flavour in it. We can hardly prevent our kid to do so. Our body isn't as weak as we think. We also eat vegetables, fresh fruits, supplemens beside some junk foods, right?
