Recently I've learned that half of the people are slow caffein metabolizers. The caffein stays longer in their system and it might negatively affect their sleep. Considering how many people drink coffee, I think a lot of people are affected by this.

I've learned to drink coffee only in the morning. If I drink coffee any time after 12PM, I'm not going to get much sleep that night. Therefore I have limited my coffee intake to medicinal purposes (i.e. as needed in order to stay awake).

I never understood the acquired taste thing. If I don’t like the taste the first time I try something then there won’t be a second time. Why acquire a taste for something you didn’t originally like?

I wonder how long my son would have survived on an exclusive McDonalds french fry diet.

I doubt your son did not like the taste of any other foods beside McDonalds french fries. I don’t understand your point.

I love my caffeine. But caffeine is an addictive, highly profitable substance. So advertising it and trying to promote it as somehow having real health benefits is widespread. I would not be surprised if routine consumption of caffeine was at least mildly detrimental to health. I think some drugs have managed to gain a special place in our society . Advertising and lobbying warps our perception of these drugs. I even…

Spinach is also mildly detrimental to health. (Oxylates) Doesn’t mean you should think that it’s bad for you unless you have a problem with kidney stones.

Both black coffee and tea have several well documented health benefits.

Even caffeine in isolation can probably have benefits when used correctly.

> caffeine addicts are standing in line at Starbucks Have you considered that those people queuing outside Starbucks might be drinking coffee because they enjoy the whole experience? Caffeine pills are an absurdity to me because I only drink coffee for the taste. Why suffer the unwanted effects of a drug without the enjoyment that it’s supposed to come with?

Overly competitive people over-optimizing everything. Why waste the time drinking a cup of coffee when you could just swallow a pill? The only enjoyment these people get are from beating others. They're not capable of appreciating a cup of coffee, or they think they're too busy to. One of them is reading this comment right now and thinking about adding "appreciate coffee" to their calendar.

This seems too defensive/aggressive. The pill guy made his case very well I think, he wanted the benefits of caffeine in a consistent dosage and pills fit that purpose. His motivation is inherently different from someone who wants to enjoy a cup of coffee, but having a different goal doesn't mean your goal is better or worse than someone else's. Nobody's "beating" anyone, and "these people" certainly don't only get enjoyment from beating others.

Caffeine does nothing for me at all, I do not get a kick when I drink coffee. It does not affect my sleep, it does not give me a boost at all. So I am a bit of jealous of those who can utilize caffeine for mental boost, I just drink it for the taste.

I used to say the same thing until I tried different types of coffee and different amounts. The average expresso doesn't do much. Also if you are already feeling well, it's unlikely you will feel a big difference unless you consume a high dosage of caffeine, which can also cause you some anxiety. Caffeine is great when we are feeling low energy or sleepy.

Thanks I will try higher dosage.

> highly profitable substance Yes and no. I've been a fan of caffeine pills for years. They are very cheap, readily available (portable), and most importantly to me offer completely consistent dosing. With caffeine pills I'm able to ensure I stay below the FDA recommended maximum daily intake of 400 mg (worst case).

I, like many others, drink a considerable amount of coffee for the taste. I typically drink decaf so it is difficult to ascribe the habit to addiction.

I must be the real sucker. I've stood in line at the cafe just to get steamed milk!

i think you are bitting the dust of getting used to the taste of a drug, just like people who drink wine, beer etc. these are literally toxic & you get a natural avoidance response the 1° time you try, with very rare cases of acceptance without repulse

I never understood the acquired taste thing. If I don’t like the taste the first time I try something then there won’t be a second time. Why acquire a taste for something you didn’t originally like?

Maybe it's cheaper or has health benefits?

I agree with you about the experience, but nobody who really likes coffee goes to Starbuck for the taste:-). They are really addicted

At the airport though it's not hard to believe Starbucks might actually be the best option.

I haven't seen this mentioned in the comments yet, so I'll mention it here. For the last year, I've seen health pundits (Huberman, etc.) recommend delaying caffeine intake for two hours after waking, for the purpose of allowing adenosine to clear from the brain first.

Ever since I've adopted this strategy, I find myself avoiding a mid-morning crash, and generally feeling more alert in the mornings. I wonder if the deleterious impact on grey matter could be mitigated in part by delaying consumption until fully awake.
