It’s very strange to include caffeine in that list of unhealthy things. Everything else in that list is proven to be bad for society/health, except for caffeine. Why did you choose to highlight caffeine consumption when there is not really any evidence it causes health issues?
I don't think there's long term evidence for negative problems. However, high dosages of caffeine are dangerous and have killed people. Those dosages are easily achieved through the likes of energy drinks.
less the caffine itself and more the amount. It sounds like they are talking more about energy drinks or some highly concentrated espresso shot.
I don't think that much caffeine is good for you, especially 4-5 times a day. But with everything else we gulp down it probably isn't priority #1.
Tangential, but I suppose this is a good time to highlight how caffeine undisclosed can in fact kill some people:
The comment said “putting 3 cups of coffee in a can we drink 4 or five of in a day” that would be 1,000–1,500 mg of caffeine. The FDA guidelines is 400mg a day and drinking 1200mg quickly can induce seizures
